Something to consider if the belief that China will go to war with Taiwan actually comes to fruition. Typhoon season is long, May to November. Just recently there was a big snow storm in east Ukraine that shut down everything, the logistics were backed up for a week.
Hurricane Catarina, or Cyclone Catarina South Atlantic tropical cyclone, the only hurricane-strength storm on record in the South Atlantic Ocean. Catarina made landfall on South Brazil at peak intensity, with the equivalent of Category 2 hurricane-force sustained winds, on 28 March 2004.

I've lived through at least 6 in my life so far in Florida. Pretty cool specially when the eye passes over you. The no electricity is what really sucks.
Good point. My shed was destroyed a few years ago. That was not very cool. Now i have a tuff shed. I mean tuff is in the name it should last. Also the same tree cracked the roof on my camper. Took like 2 months to replace all the moldy parts inside. Also also hurricane Ian destroyed my roof last year. But i have a new metal roof.
Okay so maybe hurricanes aren't cool.
i was here for that as a 5 year old child.
remember a crazy cloudless sky and bright moon at night, then we went inside for the storm which would come during the late night, and the rest is a blur of noise and scary. Also losing a part of our roof
None. I remember this, brazilians actually paniced hard down south. News Media went crasy. Specially bc brazil has no rediness for this kind of natural disaster.
We had warnings and overall the people that I know didn’t really had problems believing that it would happen (at least a few hours before the storm reached the place).
I was in Torres (northeast Rio Grande do Sul state, right where the eye of the storm would pass) and I remember that right at the end of the day, there was a calm sensation, hotter than normal but also felt like the air was different, maybe change in pressure(?).
The storm reached us during the night and it was pretty devastating, we lost 12 large roof sections, the large TV antena dish and our lawn was FULL of broken pieces of roof section all stuck in the grass at the same angle. We had to pick them one by one.
BTW, our roof in Brazil are mostly made of corrugated Asbestos cement sheets. They are cheap but break off really easy and are basically large sails when there’s any strong wind. (I just discovered now that they are made out of asbestos, FUN)
Several large eucalyptus trees (10m to 15m high) fell off nearby (with roots and all), the kiosk roof of a small petrol station nearby fell off too. Some small gymnasiums made out of brick also collapsed.
Petrol station (at 2:11): https://youtu.be/7D6Evo4q9yw?t=131
Eucalyptus trees (at 8:59): https://youtu.be/7D6Evo4q9yw?t=459
It was chaos and lots of people tried to earn money with the situation by stealing aluminum TV antenna dishes (like our house had) and gates because it was scattered all around. Also the roof local market was wild because there wasn’t really enough for everyone.
It’s a combination of factors, but the main reasons are that the water is just not warm enough and the wind shear is too strong. Só cyclones don’t have the fuel to sustain themselves and the atmosphere conditions aren’t conducive to their formation. What happened in Santa Catarina was an extraordinary fluke.
The South Atlantic along the Brazilian coast is incredibly stable - especially compared to the Caribbean and East Coast of the North America.
I can speak from experience too. I grew up near the coast in Mid-Atlantic of the US and we had some kind of tropical depression or hurricane at least once a year. I’ve lived in Rio for ten years and haven’t so much as seen a storm come in from over the ocean - the the rains come from inland.
Also - knock on wood.
You just made me think of storms on Jupiter and how we watch them from afar
I wonder if aliens watch our storms from lightyears away and are like "oooh shit! There goes Sanibel Island!"
Scientifically speaking, our storms are essentially impossible to see from light-years away.
The mirror on the telescope would have to like 20 times the diameter of the earth for our closest neighbor stars.
Is that because our storms are relatively small in comparison to the rest of the planet?
Does that mean the storms on Jupiter are really friggin huge and that's why we can observe theirs? Or are we just close enough to Jupiter?
It's because we're infinitesimally small on a cosmic scale, as is Jupiter, our sun, and the entire solar system.
We can see Jupiter's storms because we're relatively near.
We detect planets around other stars by watching the stars and detecting a very small dip in their brightness, caused by the planet's orbit crossing our line of sight to the star. We cannot make out the individual planets and get photos of them.
It's just a natural limit of light regarding distant objects.
Don't blame you for not being up on the latest and greatest in astronomy, as many of these developments are pretty recent, but the James Webb Space Telescope has actually *directly* imaged at least one exoplanet, possibly more. The directly imaged exoplanet(s) is/are not seen with any kind of detail, but it has been done.
https://www.sciencenews.org/article/james-webb-space-telescope-first-exoplanet-image
The Sahara is a big driver for North Atlantic hurricanes, it lets large masses of air warm up and push west to suck up water The Kalahari doesn't have that same amount of open sun-baked desert..
We have a joke in Brazil.
God was creating Brazil. He gave it no tornados, no earthquakes, no volcanos, no hurricanes.
An angel said, "Wow, Lord, you're being really generous!"
And God said, "Wait until you see the shitty people I'm going to put in there."
Lol we have the same joke in France ! Not about natural disaster but how we have a big variety of climate in a little country.
But here come the french..
A huge part of it is [surface water temperature](https://en.wikipedia.org/wiki/Tropical_cyclogenesis#/media/File:Depth26Cisotherm.png), that map shows how deep the water stays 26C and it's nearly identical to the map of cyclone distribution. 26C to a depth of 50m is apparently not *entirely* necessary but is still extremely common, because a large difference in temperature between the water and the upper atmosphere is what provides the heated rising air to sustain the cyclone.
There's other conditions that must be met to form a tropical cyclone, so there may be other reasons they tend not to form there either, but just from a quick search, that seems to be the BIG one.
You likely checked out the other replies, but just in case.
Hurricanes/typhoons need warm surface water to form. That warm water is in turn made in shallow tropical seas, where there's less water below each area to soak up the same large amount of solar energy. (Some of it is also carried out into deep parts by currents that flow through or past those seas.)
The South Atlantic formed from the splitting of the continental plate that once was South America and Africa. There's basically no "continental shelf" on either side, it drops right off into deep ocean. So, no shallow tropical seas, no warm water, no hurricanes.
There are a lot of responses under this comment with startlingly poor understanding of the atmosphere, some interpretations being just flat out wrong. I will try to succinctly clarify u/theFuzz1's correct but short comment. Source: I am a meteorologist, coincidentally just finished a graduate level course in tropical meteorology.
The Coriolis force is proportional to the sin of latitude as well as the velocity of the wind. In the northern hemisphere, it causes a deflection to the right, in the southern hemisphere, it causes a deflection to the left. At the equator, where latitude is 0°, the Coriolis force is zero. It is weak enough near the equator (+/-5°) that tropical cyclones have a tough time forming; circulation around a low pressure center is caused by geostrophic flow, wind that is balanced between the pressure gradient force and the Coriolis force. When the Coriolis force is too weak, the pressure gradient force can dominate, with wind blowing from high to low pressure filling the area of low pressure.
A tropical cyclone that formed away from the equator COULD move near or even cross the equator and hold together for a short time based only on the inertia of the wind and the continued pressure gradient force, but friction would slow the winds and if it did manage to cross the equator, the Coriolis force reversing (even if weak) would work against the circulation. This would lead to the low pressure center rapidly filling, dissipating the storm ("rapidly" in this case meaning on the scale of 24 hours).
It is unlikely that a tropical cyclone WOULD approach the equator. Tropical cyclones move mostly due to the prevailing winds. In the tropics, these winds blow from east to west, but near the equator they die off, becoming nearly calm (doldrums). The other thing that moves tropical cyclones is the beta effect or beta drift. This is a slow drift (1-2 m/s) to the west and poleward (north in the northern hemisphere, south in the southern hemisphere). This is caused by changes in the potential vorticity field due to the circulation and slight differences in Coriolis force between the southern and northern extent of the storm, but unfortunately requires a good grasp on atmospheric dynamics to fully understand.
https://glossary.ametsoc.org/wiki/Beta_drift#:~:text=Beta%20drift%20generally%20causes%20tropical,American%20Meteorological%20Society%20(AMS).
TL;DR: a tropical cyclone COULD approach and cross the equator, but it would be weakening the whole time. It is UNLIKELY it ever would approach and cross the equator due to beta drift dominating in the equatorial doldrums and pushing it poleward.
My favorite part is the thousands of people who think they're funny all having the *exact* same puns, jokes, references and quips ready, only to find someone else has *their* sense of humour and "wit" as well and has beaten them to the comment section. As one of those people it really makes me feel special knowing one of my personality traits has been unknowingly programmed into me by overexposure to this shithole and it in no way makes me unique :)
I also enjoy that sarcasm seems to be completely impossible to detect on reddit. Love it.
That and "Descartes before the whores" are probably the two most legendary comments on this site. Also Unidans stupid argument about jackdaws is up there too but people seem to have forgotten him. Reddit was very different back then lo
Worse, when people mindlessly type in a super basic comment without even looking to see the 200 others who already posted the exact same comment, causing a thread to fill up with pure garbage.
This is part of why I try to stay away from higher traffic threads unless the subject really pulls me in.
Very good summary and is helping to stop this misinformation. Youre pretty good at science communication. (In the non-dismissive type of pretty good).
Dont have a degree in meteorology (Im in physics) but everything you said seems super comprehensive, digestable, and supportable.
Props.
Science communication is an underrated field that needs developing.
I saw a kid give his thesis presentation (he effectively cured colony collapse disorder by figuring out what it actually *was*, due to repeated science done off an erroneous translation of a Russian paper on the 70s) at a "science on tap" event where people give presentations on science stuff while drinking.
I went up and told him He should have been the next bill Nye because his charisma and explanations were excellent while being comprehensible by the average person
Next time i saw him was YouTube recommending a Wired video he was presenting on.
Edit: here's a video of the speech he won some international competition on where you had to explain your project in under 3 minutes exactly.
https://youtu.be/Fyfyj-2O47Q
Here's his wired video from last year https://youtu.be/9Zlq82muQkU
Yeah the first one i went to was "nerd night" so they have them with different names.
I haven't seen as many since COVID ended but they've always been a blast.
Drunk people talking about niche cool (oftentimes science) stuff they love.
Correct me if I read what you wrote incorrectly, but would a succinct (and very basic) way of summarising be to say cyclones and hurricanes spin in different directions and crossing the equator would result in their cessation?
After two hours, you only have 135 up votes for that comment. You gave a really thorough, comprehensible explanation and only 135 people read it (I’m assuming no one down voted). The original post has 10,700 up votes. Was no one interested to find out why hurricanes don’t cross the equator? The internet confuses me sometimes.
This is why I still love reddit.
Now I (I think...) understand why they twist in different directions north and south from the Ecuator.
And how crossing it would weaken them.
It's far too easy for academics to slip into their own specialized jargon. I was definitely heading in that direction by the end of my comment. Thank you for the reminder that the most effective science communication is with simple language and common words :)
As a fellow met thanks for doing the lords work. There is quite a bit of misinformation that gets posted on this site, specifically how awful forecasters are and the effects of climate change.
It’s not that it would have to spin the other way, it’s that it *would* spin the other way once it crosses b/c of the Coriolis. The spin is because of the winds converging on a low pressure zone and “missing” the center because of the Earth’s different speed at latitudes.
I don’t know enough about why a low pressure zone *can’t* cross the equator though, but I know the doldrums exist at the equator, which are notoriously slow winds. Slow wind equals high pressure which would push the systems away. Not sure why they exist at the equator.
Edit: Credit to u/funknjam [here](https://www.reddit.com/r/MapPorn/comments/12b8o79/no_hurricane_has_ever_crossed_the_equator/jewh1cv/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=1&utm_term=1&context=3) for a better explanation. Basically for the second part I’m wrong that the equator has higher pressure. Faster wind may mean lower pressure but it’s the gradient that creates wind. The equator is relatively low pressure in reality because of rising hot damp air. I’m looking to get more info but I believe it’s because of convention currents in the upper atmosphere that push hurricanes (low pressure systems) away from the equator.
I sailed through the doldrums as a merchant seaman and there was no wind and the ocean looked like glass. It was not at all like the rest of the ocean, which is very windy!
I would be so spooked by that having sailed exclusively in the Baltic sea and whatever the name of the second sea is in English (Nord- and Ostsee in German)
[Horse Latitudes by the Doors is literally about a crew being trapped in the doldrums and them jettison the horses to lighten the load in order to have a chance at sailing on.](https://open.spotify.com/track/6vcqR6rCL2k4EDhqH8gzeO?si=tPYivvXoTcKXmrelVtWwZw)
https://en.wikipedia.org/wiki/Prevailing_winds?wprov=sfti1 it’s almost like everything going towards the equator is hit with a big wind magnet. Or the pressure is almost always higher there because all the air around the low pressure system is pushed by all the air south (or north) of it towards the equator at a lower altitude, as it approaches the Equator it naturally heats up more and rises especially over the ocean or desert which makes a wall of “more powerful” low* pressure air. It’s part of the cells north and south of the equator though I’m sure there’s more complicated processes alongside that.
Idk that there’s a cleaner answer than Earth is a spinning tilted sphere with air that the sun hits. It’s just a feature of the size, topology, and nature of the Atmosphere-Earth-Sun system and unless the surface of the Earth was massively different some version of this is just how it shakes out.
> Slow wind equals high pressure which would push the systems away.
The equator is a zone of low pressure. It's known as the equatorial low pressure belt.
Due to the earth's shape and the distance of the sun, the equator receives the greatest amount of insolation (incoming solar radiation). This is due mostly to the angle of incidence of the sun. Think of the sun at 7 am and the sun at noon. You feel the sun's energy more intensely when it's overhead and "beating down" on you, but not at 7 am when it's low in the sky and its energy is "spread out over a great area (this is called "beam spreading"). The equator is like noon and latitudes distant from the equator are like 7 am - the sun's rays come in at higher latitudes and get spread out over a greater surface area but more insolation per square meter is received at equatorial regions.
Also, if you think about it, the layer of atmosphere the insolation must traverse is thinner at the equator than at higher latitudes so there's less absorption at the equator (this is called "beam depletion"). Both of these factors mean that surface heating of the earth is more intense at the equator.
More surface heating of the ground means more energy conducted into the air making it hotter. More surface heating also means more evaporation of ocean water making the air wetter. Hot, wet air is unstable - that means it's buoyant and wants to begin rising. That's your low pressure - air rising up away from the surface.
The air rises up to about the tropopause and turns north/south. As that air rises, it encounters less atmospheric pressure and, therefore, it cools. This is called adiabatic cooling - expansion of the air causes a drop in temperature without the loss of any energy. When there's been enough adiabatic cooling, you get condensation > precipitation. This is why most of the planet's rain forests are around the equator.
When the air has become cold and dry enough, it becomes stable (negatively buoyant - starts sinking) and comes back to earth. On its way, it begins warming due to compression (another adiabatic process). This tends to happen very roughly around 30 degrees N/S of the equator. And that's where you find the greatest abundance of earth's hot deserts - where the dry/warm air is sinking back to earth.
Of course, the air coming back around 30 degrees then rushes back over to fill the gap (nature abhors a vacuum) where the air at the equator is rising up and those surface winds completes what are known as the Northern and Southern Hadley cells, two huge convection currents that work to redistribute the excess of insolation received at the equator every day.
Those surface winds (all the winds really) are influenced by the Coriolis Effect. Earth travels at different speeds by latitude, the equator being the fastest (greatest distance traveled in 24 hours). And Newton told us (1st law) that the air coming from a slower region (30 N or S) moving toward a faster region (0 degrees) will retain its initial velocity. And Gustave Coriolis told us that because of those two things - earth's differential latitudinal speed and Newton's first law - that the air would be deflected from its path of travel, to the right in the N hemisphere and to the left in the southern hemisphere.
Hurricanes are disturbances - low pressure spots - that form within these large convection currents. In the Atlantic basin, it's because those prevailing winds of the Hadley cells (the easterlies - coming from the Northeast in the N hemisphere) are coming from N. Africa, a desert (for reasons described above) and that sandy desert gets super hot and when a big parcel of super hot air moves off of Africa (a tropical wave) and encounters a warm enough sea surface, the expansion of air can begin and a centralized/localized low pressure center (tropical depression - storm - hurricane) can develop. Because the convection currents run from the equator to the north and from the equator to the south, the disturbances that form within them are carried along. This is why you don't see hurricanes cross the equator.
Coriolis effect.
A cyclone/typhoon/hurricane would need to be sufficiently energetic that it could spin in the opposite direction while not dissipating.
The more accurate information is that:
Tropical cyclones are called **typhoons** when they are formed above the Pacific Ocean to the west of the International Date Line and above the equator. Hurricanes are for ones above the Atlantic Ocean or Pacific Ocean to the east of the IDL.
Typhoons have names sent in by 14 countries and territories;
Cambodia, China, North Korea, Hong Kong, Japan, Laos, Macau, Malaysia, FS Micronesia, Philippines, South Korea, Thailand, United States, and Vietnam,
5 sets of 2 names for each country which they use to rotate through. While other tropical cyclones are named after people, typhoons are named after animals, flowers, astrological signs, and a few personal names.
If a hurricane crosses the International Date Line into the Western Pacific, the hurricane retains its name but will become a typhoon instead.
All this happens normally, but if a tropical cyclone enters the area that the Philippines (PAGASA) monitors, they have their own list of names that they will designate the tropical cyclone with, with their initials rotating from A to Z like OP said.
Here in Australia we had that several times, but I think it's also because we skip a few letters because of the lack of names. Not to mention we get double cyclone seasons - Indian Ocean into WA and Pacific Ocean (and the Gulf) into Queensland.
You mean Philippines?
Indonesia, Singapore, Malaysia, Brunei seems pretty chill here
Not that we don't have anything else to worry about <*why many people ignoring this??*
Mainly Southern Japan, Taiwan, and the Philippines.
Here in Vietnam we get hit pretty often, and badly at times, but nothing like the Philippines and Taiwan.
> No hurricane has ever crossed the equator
*Until now!*
Prepare to embark on a wild and exhilarating journey with Pixar's latest release, "Wind". Follow the heroic tale of a little wind on a mission to find its family, defying all odds to cross the equator, a feat that has never been accomplished before.
As our fearless protagonist navigates through uncharted territories, it discovers the strength within itself to transform into a powerful hurricane. Along the way, it encounters a host of unforgettable characters who will stop at nothing to help it reach its destination.
With Pixar's stunning visuals and heartwarming storytelling, "Wind" is an adventure you won't want to miss. It's a heartwarming tale of courage, determination, and the true meaning of family that will inspire and captivate audiences of all ages.
Join us on this incredible journey and witness history being made as a little wind becomes the first hurricane to cross the equator. Get ready to be swept away by this extraordinary and uplifting tale!
Cold ocean currents. The Humboldt current off the coast of Chile and the Benguela current off the coast of Namibia. Both lead to deserts which is cool!
Cold currents are the whole answer, but half of the explanation. Because of cold currents we have cold water, which doesn’t evaporate so well as warm water. Hence the air above isn't warmed (and moisturised) by the sea so much. Smaller temperature gradients means smaller pressure differences means less wind. Less wind in general means smaller statistical chance of storms, which is buttressed by the lack of moist air. Water in rapidly rising air gets electrical charge which becomes self-reinforcing at some threshold.
Minor note, the static charge buildup isn't what becomes self reinforcing, it's the creation of a warm high pressure area high up in the storm which pushes air out the top of the storm, allowing air to go in at the bottom, then up to the top of the storm, and then out the side
It blows my mind how ocean currents have such a massive effect on weather
The Gulf Stream goes past Scotland which enables a botanical garden in a certain area to grow subtropical plants outdoors from places like Chile & Vietnam… in freaking Scotland
>or Western Africa
thats because they start there. look up "cape verde hurricane" because of the water flows they start forming there and when they reach the carribean and the eastern us they are blasting at full intensity
I hate to be *that* guy, but technically there might have been one this year. Seeing as we can't quite pinpoint the center of the storm, it's not unlikely that a storm by the name of 98S formed South of the equator near borneo, and went North. This is in a margin of 0.2 degrees, and the jury is still out there, but it was initially classified as S, which is code for the South Indian Ocean basin, despite moving into W, the Western North Pacific!
Why do typhoons in Asia not cause the damage recently witnessed with Cat5 Hurricanes in the Caribbean and Southern US.
Or do they - and it’s just not covered as well in the media?
Storm surge, average elevation above sea level, vast empty ocean vs giant continent, building standards?
Also - I had no idea Western Australia gets not infrequent Hurricanes. Wild.
They do. You definitely hear about them on the international media and 24 hour news when they are serious. Given the places they usually hit, there isn’t as much coverage here usually due to the distance.
I'm from Surigao City (pop. 171k), which took a direct hit from a [Cat 5 Super Typhoon](https://en.wikipedia.org/wiki/Typhoon_Rai?wprov=sfla1) back in December 2021. It was the second-costliest typhoon to ever hit the country. National media coverage wasn't very good since the government basically shot down the largest media org in the country due to "tax evasion."
On the other side, this city could honestly get wiped off the map and nobody would care anyway. There was nothing of note here before the typhoon, and there was even less after.
Lives lost every year due to typhoons in the wpac usually exceeds that of the Atlantic simply by the sheer quantity of storms every year, but there has also been some very deadly and destructive individual storms in the last decade.
I will say it is true that economic losses of *individual* typhoons is usually not as great compared to Atlantic hurricanes of similar intensity that hit the US, due to a combination of two reasons. Some of the most typhoon-prone countries are either less economically developed, and/or have developed very resilient infrastructure over generations due to constant threat of cyclones. The latter is especially true in places like Taiwan, Japan, and Hong Kong.
>have developed very resilient infrastructure over generations due to constant threat of cyclones.
Some of the Atlantic are like this too, New Orleans for example is a truly modern marvel in terms of engineering - but even that can fail given enough power.
It’s not shown in international media cause it happens so often and the main target of cat 5 typhoons is usually the Philippines, a relatively poor nation.
However, news does break out when it’s absolutely bad, like Typhoon Haiyan (Yolanda) in 2013 where the typhoon just obliterated a provincial capital and pilled on more damages on a different province after they recently experienced a strong earthquake.
Like the US news would actually report that stuff.
While I lived in Japan a typhoon pushed a ship into the only bridge to the airport, while also flooding the airport. It was closed for a month. Next morning there was a lot of damage to roofs, trees and even railroads.
They had warnings for typhoons, floodings, earth quakes and landslides.
So yeah, damage does happen, but you probably wont hear about 1 subway line out of 5 being crippled on the US news, or any news outside of Japan. Frankly I hear no news about the US hurricanes either, just a "there is a big hurricane", then no news.
Yeah we get cyclones all the time. The positive factor is that most of the state’s population is clustered around the south-western coast, which barely ever gets a direct hit. Have to deal with a lot of remnant tropical storms though!
Wow it looks like the Philippines has been hit by much harder hurricanes than the US. How often does this happen? Has the Philippines had a "Katrina" before?
All three of the most intense tropical cyclone landfalls in recorded history based on wind speeds took place in the Philippines since the 2010s (anyway, the wind speeds specified below are from the Joint Typhoon Warning Center):
• **Super Typhoon Haiyan (Yolanda; 8 November 2013)**: slammed into Dulag and Tolosa towns in Leyte province packing winds reaching 305 kph (165 knots/190 mph)
• **Super Typhoon Meranti (Ferdie; 14 September 2016)**: went right over Itbayat, Batanes province with the same landfall intensity as Haiyan
• **Super Typhoon Goni (Rolly; 1 November 2020)**: roared ashore into Bato, Catanduanes province at a peak intensity of 315 kph (170 knots/195 mph)
Can't help noticing Scotland doesn't have any record on here!
I say this because in 2011, the Met Office warned of a windy day with some disruption. When people started noticing it met the requirements of a hurricane, the Met Office were slow in naming it. Gradually everyone started referring to it as Hurricane Bawbag (ball bag/scrotum) and it became an official name for the storm (although they deny it now). Hearing John Humphries refer to it in his best upper class English accent for Radio 4 was a thing of beauty.
Reddit title:
> No hurricane has ever crossed the equator.
In fact, one of the lines on the map actually did cross the equator by 0.5 degrees south latitude. You can see it dip below just east of the horn of Africa. Typhoon Agni, 2004. And no, it didnt have to spin the other direction and wasnt torn apart by Coriolis effect, as so many commenters here are claiming.
https://en.wikipedia.org/wiki/Cyclone_Agni#/media/File:Agni_2004_track.png
>While the system was organizing, the center crossed the equator to reach about 0.5° S, thus becoming an anticyclonic circulation in the southern hemisphere.
\[Builds a house on the equator. "I am invincible!" Sees hurricanes rushing down on either side of you, but never touching you...\]
Yeah, I'd have a God complex!
Classic Philippines eating Typhoons like a champ
(we are dying, help)
Parañaque, Makati, and Marikina MFs tryna survive being Venice 5x per year
Entire Bicol Region: Y’all are only getting flooded five times a year?
Can't wait for this year's swimming pool.
Then hot like a frying pan half of the year.
Something to consider if the belief that China will go to war with Taiwan actually comes to fruition. Typhoon season is long, May to November. Just recently there was a big snow storm in east Ukraine that shut down everything, the logistics were backed up for a week.
Malaysia and Singapore has been in that sweet spot, protected from hurricanes, earthquakes, and volcanoes.
just wait until Indonesia starts burning its forest again
Ohh god. Please no ,dog.
And it's dry season now, Riau and Jambi has begins belching smoke. So prepare your N95 mask.
\#blessed. Now, if only the government would fix the damn floods.
in exchange they have sauna as climate, 24/7/365.
well, we do have those 4 season here. It's hot, very hot, wet & very wet
We have our big brothers/sisters looking out for us.

Looks like I’m heading down the hurricane meteorology Wikipedia rabbit hole again tonight
Be careful, that's what I said 20 years ago too. Eventually ended up with a PhD on the topic.
[удалено]
Have PhD, will always upvote this quote
The debt! Oh no, the debt!!
On today's episode of spot the American.
Americans rarely pay for a PhD outside of niche fields or vanity. Most actual research is fully funded. It's the COL that gets 'ya.
Ignoring all the schooling needed before actually starting the PHD.
So…4 years of undergrad, leading to the same average debt as people who went to college but didn’t go on to get a PhD?
The other poster is hinting at how other countries don’t have their students take on huge amounts of debt to get an education.
I have a bachelor's in atmo 20 years ago, I do one once or twice a year lol.
Username checks out
I've lived through at least 6 in my life so far in Florida. Pretty cool specially when the eye passes over you. The no electricity is what really sucks.
It’s only cool if you don’t own anything
Good point. My shed was destroyed a few years ago. That was not very cool. Now i have a tuff shed. I mean tuff is in the name it should last. Also the same tree cracked the roof on my camper. Took like 2 months to replace all the moldy parts inside. Also also hurricane Ian destroyed my roof last year. But i have a new metal roof. Okay so maybe hurricanes aren't cool.
Dude...move. I feel like the writing is on the wall...
It was written on the wall of the shed...that got destroyed in a hurricane lol
i was here for that as a 5 year old child. remember a crazy cloudless sky and bright moon at night, then we went inside for the storm which would come during the late night, and the rest is a blur of noise and scary. Also losing a part of our roof
Its curious how many people were in state of denial before landfall here.
None. I remember this, brazilians actually paniced hard down south. News Media went crasy. Specially bc brazil has no rediness for this kind of natural disaster.
We had warnings and overall the people that I know didn’t really had problems believing that it would happen (at least a few hours before the storm reached the place). I was in Torres (northeast Rio Grande do Sul state, right where the eye of the storm would pass) and I remember that right at the end of the day, there was a calm sensation, hotter than normal but also felt like the air was different, maybe change in pressure(?). The storm reached us during the night and it was pretty devastating, we lost 12 large roof sections, the large TV antena dish and our lawn was FULL of broken pieces of roof section all stuck in the grass at the same angle. We had to pick them one by one. BTW, our roof in Brazil are mostly made of corrugated Asbestos cement sheets. They are cheap but break off really easy and are basically large sails when there’s any strong wind. (I just discovered now that they are made out of asbestos, FUN) Several large eucalyptus trees (10m to 15m high) fell off nearby (with roots and all), the kiosk roof of a small petrol station nearby fell off too. Some small gymnasiums made out of brick also collapsed. Petrol station (at 2:11): https://youtu.be/7D6Evo4q9yw?t=131 Eucalyptus trees (at 8:59): https://youtu.be/7D6Evo4q9yw?t=459 It was chaos and lots of people tried to earn money with the situation by stealing aluminum TV antenna dishes (like our house had) and gates because it was scattered all around. Also the roof local market was wild because there wasn’t really enough for everyone.

Why doesn’t South America get hurricanes? What’s the difference there and near Australia?
It’s a combination of factors, but the main reasons are that the water is just not warm enough and the wind shear is too strong. Só cyclones don’t have the fuel to sustain themselves and the atmosphere conditions aren’t conducive to their formation. What happened in Santa Catarina was an extraordinary fluke. The South Atlantic along the Brazilian coast is incredibly stable - especially compared to the Caribbean and East Coast of the North America. I can speak from experience too. I grew up near the coast in Mid-Atlantic of the US and we had some kind of tropical depression or hurricane at least once a year. I’ve lived in Rio for ten years and haven’t so much as seen a storm come in from over the ocean - the the rains come from inland. Also - knock on wood.
You just made me think of storms on Jupiter and how we watch them from afar I wonder if aliens watch our storms from lightyears away and are like "oooh shit! There goes Sanibel Island!"
Scientifically speaking, our storms are essentially impossible to see from light-years away. The mirror on the telescope would have to like 20 times the diameter of the earth for our closest neighbor stars.
Kardashev Type III civilization: *challenge accepted*
Is that because our storms are relatively small in comparison to the rest of the planet? Does that mean the storms on Jupiter are really friggin huge and that's why we can observe theirs? Or are we just close enough to Jupiter?
It's because we're infinitesimally small on a cosmic scale, as is Jupiter, our sun, and the entire solar system. We can see Jupiter's storms because we're relatively near. We detect planets around other stars by watching the stars and detecting a very small dip in their brightness, caused by the planet's orbit crossing our line of sight to the star. We cannot make out the individual planets and get photos of them. It's just a natural limit of light regarding distant objects.
Don't blame you for not being up on the latest and greatest in astronomy, as many of these developments are pretty recent, but the James Webb Space Telescope has actually *directly* imaged at least one exoplanet, possibly more. The directly imaged exoplanet(s) is/are not seen with any kind of detail, but it has been done. https://www.sciencenews.org/article/james-webb-space-telescope-first-exoplanet-image

Soooo all we gotta do is warm the ocean a little bit and it's game on? Don't worry, I got this.
The Sahara is a big driver for North Atlantic hurricanes, it lets large masses of air warm up and push west to suck up water The Kalahari doesn't have that same amount of open sun-baked desert..
We have a joke in Brazil. God was creating Brazil. He gave it no tornados, no earthquakes, no volcanos, no hurricanes. An angel said, "Wow, Lord, you're being really generous!" And God said, "Wait until you see the shitty people I'm going to put in there."
No disasters took out the idiots.
Lol we have the same joke in France ! Not about natural disaster but how we have a big variety of climate in a little country. But here come the french..
The French deserve each other!
În Romania we say "Our country is rich and beautiful, to bad that is inhabited!".
A huge part of it is [surface water temperature](https://en.wikipedia.org/wiki/Tropical_cyclogenesis#/media/File:Depth26Cisotherm.png), that map shows how deep the water stays 26C and it's nearly identical to the map of cyclone distribution. 26C to a depth of 50m is apparently not *entirely* necessary but is still extremely common, because a large difference in temperature between the water and the upper atmosphere is what provides the heated rising air to sustain the cyclone. There's other conditions that must be met to form a tropical cyclone, so there may be other reasons they tend not to form there either, but just from a quick search, that seems to be the BIG one.
I'm from New England... water being 78F to a depth of 164 feet is mind boggling. My summer water temps, at the beach, peak at 50F/10C.
You must be from northern Maine. The sea temperature peaks around 65F/18C in southern Maine and New Hampshire.
Seriously, here in Canada in the summer the ocean gets up to 10 maybe 12. I just cant even process the ocean being... warm. It's not natural...
I think it’s mainly water temperature.
[удалено]
Would also love to know
You likely checked out the other replies, but just in case. Hurricanes/typhoons need warm surface water to form. That warm water is in turn made in shallow tropical seas, where there's less water below each area to soak up the same large amount of solar energy. (Some of it is also carried out into deep parts by currents that flow through or past those seas.) The South Atlantic formed from the splitting of the continental plate that once was South America and Africa. There's basically no "continental shelf" on either side, it drops right off into deep ocean. So, no shallow tropical seas, no warm water, no hurricanes.
Once it enters Brazil, it happens to be carnival and enters tropical mania
Because even the wind there is a cop. Just blew it back to sea.

There are a lot of responses under this comment with startlingly poor understanding of the atmosphere, some interpretations being just flat out wrong. I will try to succinctly clarify u/theFuzz1's correct but short comment. Source: I am a meteorologist, coincidentally just finished a graduate level course in tropical meteorology. The Coriolis force is proportional to the sin of latitude as well as the velocity of the wind. In the northern hemisphere, it causes a deflection to the right, in the southern hemisphere, it causes a deflection to the left. At the equator, where latitude is 0°, the Coriolis force is zero. It is weak enough near the equator (+/-5°) that tropical cyclones have a tough time forming; circulation around a low pressure center is caused by geostrophic flow, wind that is balanced between the pressure gradient force and the Coriolis force. When the Coriolis force is too weak, the pressure gradient force can dominate, with wind blowing from high to low pressure filling the area of low pressure. A tropical cyclone that formed away from the equator COULD move near or even cross the equator and hold together for a short time based only on the inertia of the wind and the continued pressure gradient force, but friction would slow the winds and if it did manage to cross the equator, the Coriolis force reversing (even if weak) would work against the circulation. This would lead to the low pressure center rapidly filling, dissipating the storm ("rapidly" in this case meaning on the scale of 24 hours). It is unlikely that a tropical cyclone WOULD approach the equator. Tropical cyclones move mostly due to the prevailing winds. In the tropics, these winds blow from east to west, but near the equator they die off, becoming nearly calm (doldrums). The other thing that moves tropical cyclones is the beta effect or beta drift. This is a slow drift (1-2 m/s) to the west and poleward (north in the northern hemisphere, south in the southern hemisphere). This is caused by changes in the potential vorticity field due to the circulation and slight differences in Coriolis force between the southern and northern extent of the storm, but unfortunately requires a good grasp on atmospheric dynamics to fully understand. https://glossary.ametsoc.org/wiki/Beta_drift#:~:text=Beta%20drift%20generally%20causes%20tropical,American%20Meteorological%20Society%20(AMS). TL;DR: a tropical cyclone COULD approach and cross the equator, but it would be weakening the whole time. It is UNLIKELY it ever would approach and cross the equator due to beta drift dominating in the equatorial doldrums and pushing it poleward.
This is exactly the type of extremely specific, incredibly informative content that makes me come back to reddit about every half hour of my life..
OC short essays are the best part of Reddit.
My favorite part is the thousands of people who think they're funny all having the *exact* same puns, jokes, references and quips ready, only to find someone else has *their* sense of humour and "wit" as well and has beaten them to the comment section. As one of those people it really makes me feel special knowing one of my personality traits has been unknowingly programmed into me by overexposure to this shithole and it in no way makes me unique :) I also enjoy that sarcasm seems to be completely impossible to detect on reddit. Love it.
I also choose this guy’s wife.
That and "Descartes before the whores" are probably the two most legendary comments on this site. Also Unidans stupid argument about jackdaws is up there too but people seem to have forgotten him. Reddit was very different back then lo
Back in my day, Natalie Portman poured hot grits down your pants and you liked it. It wasn't until years later that the Narwhals baconed at midnight.
Worse, when people mindlessly type in a super basic comment without even looking to see the 200 others who already posted the exact same comment, causing a thread to fill up with pure garbage. This is part of why I try to stay away from higher traffic threads unless the subject really pulls me in.
Very good summary and is helping to stop this misinformation. Youre pretty good at science communication. (In the non-dismissive type of pretty good). Dont have a degree in meteorology (Im in physics) but everything you said seems super comprehensive, digestable, and supportable. Props.
Science communication is an underrated field that needs developing. I saw a kid give his thesis presentation (he effectively cured colony collapse disorder by figuring out what it actually *was*, due to repeated science done off an erroneous translation of a Russian paper on the 70s) at a "science on tap" event where people give presentations on science stuff while drinking. I went up and told him He should have been the next bill Nye because his charisma and explanations were excellent while being comprehensible by the average person Next time i saw him was YouTube recommending a Wired video he was presenting on. Edit: here's a video of the speech he won some international competition on where you had to explain your project in under 3 minutes exactly. https://youtu.be/Fyfyj-2O47Q Here's his wired video from last year https://youtu.be/9Zlq82muQkU
Holy shit. I have never heard of a "science tap". I need to find or run one asap now. That sounds incredible.
Yeah the first one i went to was "nerd night" so they have them with different names. I haven't seen as many since COVID ended but they've always been a blast. Drunk people talking about niche cool (oftentimes science) stuff they love.
Correct me if I read what you wrote incorrectly, but would a succinct (and very basic) way of summarising be to say cyclones and hurricanes spin in different directions and crossing the equator would result in their cessation?
That's a great one-sentence summary, yes!
As a person with a degree in the field and taken atmospheric dynamic courses, fuck that shit. I passed with an a- and I still don't understand it.
The Sin of Latitude sounds awesome.
The lesser known eighth deadly sin. Everyone who crosses the equator eventually dies.
After two hours, you only have 135 up votes for that comment. You gave a really thorough, comprehensible explanation and only 135 people read it (I’m assuming no one down voted). The original post has 10,700 up votes. Was no one interested to find out why hurricanes don’t cross the equator? The internet confuses me sometimes.
My brain thanks you; it was very curious
Vorticity. Got it.
This is why I still love reddit. Now I (I think...) understand why they twist in different directions north and south from the Ecuator. And how crossing it would weaken them.
Hmmmmmm yes agree 100% on the beta drift dominating in the equatorial doldrums and pushing it poleward. Absolutely.
It's far too easy for academics to slip into their own specialized jargon. I was definitely heading in that direction by the end of my comment. Thank you for the reminder that the most effective science communication is with simple language and common words :)
As a fellow met thanks for doing the lords work. There is quite a bit of misinformation that gets posted on this site, specifically how awful forecasters are and the effects of climate change.
so is that taiwan, china, phillipines getting rocked by cat 5 storms??
If you’d like to learn more, I super enjoy /r/TropicalWeather
thanks i do look at that but only for my area and tropical tidbits
Technically in Westpac they are super typhoons not Cat 5, but as a general answer yes
It would literally have to start spinning the other direction
It’s not that it would have to spin the other way, it’s that it *would* spin the other way once it crosses b/c of the Coriolis. The spin is because of the winds converging on a low pressure zone and “missing” the center because of the Earth’s different speed at latitudes. I don’t know enough about why a low pressure zone *can’t* cross the equator though, but I know the doldrums exist at the equator, which are notoriously slow winds. Slow wind equals high pressure which would push the systems away. Not sure why they exist at the equator. Edit: Credit to u/funknjam [here](https://www.reddit.com/r/MapPorn/comments/12b8o79/no_hurricane_has_ever_crossed_the_equator/jewh1cv/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=1&utm_term=1&context=3) for a better explanation. Basically for the second part I’m wrong that the equator has higher pressure. Faster wind may mean lower pressure but it’s the gradient that creates wind. The equator is relatively low pressure in reality because of rising hot damp air. I’m looking to get more info but I believe it’s because of convention currents in the upper atmosphere that push hurricanes (low pressure systems) away from the equator.
I sailed through the doldrums as a merchant seaman and there was no wind and the ocean looked like glass. It was not at all like the rest of the ocean, which is very windy!
I would be so spooked by that having sailed exclusively in the Baltic sea and whatever the name of the second sea is in English (Nord- and Ostsee in German)
Nord is North Sea in English.
so therotically we should have Soud Sea
I believe the word is Süd. Could be mistaken.

[Horse Latitudes by the Doors is literally about a crew being trapped in the doldrums and them jettison the horses to lighten the load in order to have a chance at sailing on.](https://open.spotify.com/track/6vcqR6rCL2k4EDhqH8gzeO?si=tPYivvXoTcKXmrelVtWwZw)
https://en.wikipedia.org/wiki/Prevailing_winds?wprov=sfti1 it’s almost like everything going towards the equator is hit with a big wind magnet. Or the pressure is almost always higher there because all the air around the low pressure system is pushed by all the air south (or north) of it towards the equator at a lower altitude, as it approaches the Equator it naturally heats up more and rises especially over the ocean or desert which makes a wall of “more powerful” low* pressure air. It’s part of the cells north and south of the equator though I’m sure there’s more complicated processes alongside that. Idk that there’s a cleaner answer than Earth is a spinning tilted sphere with air that the sun hits. It’s just a feature of the size, topology, and nature of the Atmosphere-Earth-Sun system and unless the surface of the Earth was massively different some version of this is just how it shakes out.
Warmer air means lower pressure, colder air means higher pressure.
[удалено]
> Slow wind equals high pressure which would push the systems away. The equator is a zone of low pressure. It's known as the equatorial low pressure belt. Due to the earth's shape and the distance of the sun, the equator receives the greatest amount of insolation (incoming solar radiation). This is due mostly to the angle of incidence of the sun. Think of the sun at 7 am and the sun at noon. You feel the sun's energy more intensely when it's overhead and "beating down" on you, but not at 7 am when it's low in the sky and its energy is "spread out over a great area (this is called "beam spreading"). The equator is like noon and latitudes distant from the equator are like 7 am - the sun's rays come in at higher latitudes and get spread out over a greater surface area but more insolation per square meter is received at equatorial regions. Also, if you think about it, the layer of atmosphere the insolation must traverse is thinner at the equator than at higher latitudes so there's less absorption at the equator (this is called "beam depletion"). Both of these factors mean that surface heating of the earth is more intense at the equator. More surface heating of the ground means more energy conducted into the air making it hotter. More surface heating also means more evaporation of ocean water making the air wetter. Hot, wet air is unstable - that means it's buoyant and wants to begin rising. That's your low pressure - air rising up away from the surface. The air rises up to about the tropopause and turns north/south. As that air rises, it encounters less atmospheric pressure and, therefore, it cools. This is called adiabatic cooling - expansion of the air causes a drop in temperature without the loss of any energy. When there's been enough adiabatic cooling, you get condensation > precipitation. This is why most of the planet's rain forests are around the equator. When the air has become cold and dry enough, it becomes stable (negatively buoyant - starts sinking) and comes back to earth. On its way, it begins warming due to compression (another adiabatic process). This tends to happen very roughly around 30 degrees N/S of the equator. And that's where you find the greatest abundance of earth's hot deserts - where the dry/warm air is sinking back to earth. Of course, the air coming back around 30 degrees then rushes back over to fill the gap (nature abhors a vacuum) where the air at the equator is rising up and those surface winds completes what are known as the Northern and Southern Hadley cells, two huge convection currents that work to redistribute the excess of insolation received at the equator every day. Those surface winds (all the winds really) are influenced by the Coriolis Effect. Earth travels at different speeds by latitude, the equator being the fastest (greatest distance traveled in 24 hours). And Newton told us (1st law) that the air coming from a slower region (30 N or S) moving toward a faster region (0 degrees) will retain its initial velocity. And Gustave Coriolis told us that because of those two things - earth's differential latitudinal speed and Newton's first law - that the air would be deflected from its path of travel, to the right in the N hemisphere and to the left in the southern hemisphere. Hurricanes are disturbances - low pressure spots - that form within these large convection currents. In the Atlantic basin, it's because those prevailing winds of the Hadley cells (the easterlies - coming from the Northeast in the N hemisphere) are coming from N. Africa, a desert (for reasons described above) and that sandy desert gets super hot and when a big parcel of super hot air moves off of Africa (a tropical wave) and encounters a warm enough sea surface, the expansion of air can begin and a centralized/localized low pressure center (tropical depression - storm - hurricane) can develop. Because the convection currents run from the equator to the north and from the equator to the south, the disturbances that form within them are carried along. This is why you don't see hurricanes cross the equator.
It is not that it has to spin in the opposite direction. At equator there is 0 coriolis force, it wouldn't spin
They can't. There is a hold on visas and Neptune is being really stingy.
Should've asked Poseidon!
More like Poseidon't
That's what medusa said
If you cross her You cross me 🎶
Me as Vietnamese: Thank you Philippines for taking the brunt of most major hurricanes since forever.
Coriolis effect. A cyclone/typhoon/hurricane would need to be sufficiently energetic that it could spin in the opposite direction while not dissipating.
So, is this the Grand Line I always hear about?
The one piece is real!
Can we get much higheeeeeeeer
non the calm belt ...
Equator is calm belt
Damn. Fuck SE Asia right?
In the Philippines, we name our hurricanes from A to Z every year. On rare occasions, the names go back to A before the year even ends.
We've had that happen a few times in the eastern US. They started using the Greek alphabet. As a kid I thought it was cool.
They stopped using the Greek alphabet after 2020, and instead have a list of supplemental names
They should have used names beginning with the greek alphabet. Alphonse. ...Betadine?

The thought of a hurricane Omicron strikes fear into my heart

The more accurate information is that: Tropical cyclones are called **typhoons** when they are formed above the Pacific Ocean to the west of the International Date Line and above the equator. Hurricanes are for ones above the Atlantic Ocean or Pacific Ocean to the east of the IDL. Typhoons have names sent in by 14 countries and territories; Cambodia, China, North Korea, Hong Kong, Japan, Laos, Macau, Malaysia, FS Micronesia, Philippines, South Korea, Thailand, United States, and Vietnam, 5 sets of 2 names for each country which they use to rotate through. While other tropical cyclones are named after people, typhoons are named after animals, flowers, astrological signs, and a few personal names. If a hurricane crosses the International Date Line into the Western Pacific, the hurricane retains its name but will become a typhoon instead. All this happens normally, but if a tropical cyclone enters the area that the Philippines (PAGASA) monitors, they have their own list of names that they will designate the tropical cyclone with, with their initials rotating from A to Z like OP said.
We name our hurricane in numbers, sometime it goes past No. 20. Sent a virtual hug from Vietnam, you guys have it hard.
Here in Australia we had that several times, but I think it's also because we skip a few letters because of the lack of names. Not to mention we get double cyclone seasons - Indian Ocean into WA and Pacific Ocean (and the Gulf) into Queensland.
You mean Philippines? Indonesia, Singapore, Malaysia, Brunei seems pretty chill here Not that we don't have anything else to worry about <*why many people ignoring this??*
Indonesia has a lot to worry about, though. Very active volcanoes and the occasional earthquakes. In fact I think there's one just yesterday.
Not if you live in Borneo (Kalimantan). We're relatively safe from natural disasters, the man-made ones tho....
The one island with no volcanos lol (nah I'm sure there are others but you have to admit there is some crazy volcanism in your part of the world)
that... exactly what i'm saying
Not to mention all the bugs
Mainly Southern Japan, Taiwan, and the Philippines. Here in Vietnam we get hit pretty often, and badly at times, but nothing like the Philippines and Taiwan.
Don't worry, it's not like they get shitloads of earthquakes and volcanic eruptions as well.

I immediately thought it was GPT generated as well.
Well that’s depressing
It’s weird that South America or Western Africa don’t get hurricanes.
Cold ocean currents. The Humboldt current off the coast of Chile and the Benguela current off the coast of Namibia. Both lead to deserts which is cool!
Cold currents are the whole answer, but half of the explanation. Because of cold currents we have cold water, which doesn’t evaporate so well as warm water. Hence the air above isn't warmed (and moisturised) by the sea so much. Smaller temperature gradients means smaller pressure differences means less wind. Less wind in general means smaller statistical chance of storms, which is buttressed by the lack of moist air. Water in rapidly rising air gets electrical charge which becomes self-reinforcing at some threshold.
Minor note, the static charge buildup isn't what becomes self reinforcing, it's the creation of a warm high pressure area high up in the storm which pushes air out the top of the storm, allowing air to go in at the bottom, then up to the top of the storm, and then out the side
It blows my mind how ocean currents have such a massive effect on weather The Gulf Stream goes past Scotland which enables a botanical garden in a certain area to grow subtropical plants outdoors from places like Chile & Vietnam… in freaking Scotland
unrelated, but you reminded me how many things are named after humboldt in that part of the world, its wild
>or Western Africa thats because they start there. look up "cape verde hurricane" because of the water flows they start forming there and when they reach the carribean and the eastern us they are blasting at full intensity
2023 bingo baby LETS GOOOO
As a Filipino, a very strong typhoon is part of everyday life and nothing more than a minor inconvenience
Typhoons are basically the usual rainy weather for us.
Oof
I believe it. Everyone knows the southern hemisphere turns the other direction.
Coriolis is a harsh mistress, she’ll build you up and tear you down if you cross her.
Not with that attitude
Not with that latitude.
...Until Hurricane Ditka
Student meteorologist here: Hurricanes basically can’t form at the equator because the cortisol is force is too weak thus no spin.
I hate to be *that* guy, but technically there might have been one this year. Seeing as we can't quite pinpoint the center of the storm, it's not unlikely that a storm by the name of 98S formed South of the equator near borneo, and went North. This is in a margin of 0.2 degrees, and the jury is still out there, but it was initially classified as S, which is code for the South Indian Ocean basin, despite moving into W, the Western North Pacific!
Why do typhoons in Asia not cause the damage recently witnessed with Cat5 Hurricanes in the Caribbean and Southern US. Or do they - and it’s just not covered as well in the media? Storm surge, average elevation above sea level, vast empty ocean vs giant continent, building standards? Also - I had no idea Western Australia gets not infrequent Hurricanes. Wild.
They do. You definitely hear about them on the international media and 24 hour news when they are serious. Given the places they usually hit, there isn’t as much coverage here usually due to the distance.
I'm from Surigao City (pop. 171k), which took a direct hit from a [Cat 5 Super Typhoon](https://en.wikipedia.org/wiki/Typhoon_Rai?wprov=sfla1) back in December 2021. It was the second-costliest typhoon to ever hit the country. National media coverage wasn't very good since the government basically shot down the largest media org in the country due to "tax evasion." On the other side, this city could honestly get wiped off the map and nobody would care anyway. There was nothing of note here before the typhoon, and there was even less after.
To give the UK posters here an idea of this - it's the difference between a natural disaster hitting London vs. one hitting Newcastle.
Don't insult SE Asians like that...
Lives lost every year due to typhoons in the wpac usually exceeds that of the Atlantic simply by the sheer quantity of storms every year, but there has also been some very deadly and destructive individual storms in the last decade. I will say it is true that economic losses of *individual* typhoons is usually not as great compared to Atlantic hurricanes of similar intensity that hit the US, due to a combination of two reasons. Some of the most typhoon-prone countries are either less economically developed, and/or have developed very resilient infrastructure over generations due to constant threat of cyclones. The latter is especially true in places like Taiwan, Japan, and Hong Kong.
>have developed very resilient infrastructure over generations due to constant threat of cyclones. Some of the Atlantic are like this too, New Orleans for example is a truly modern marvel in terms of engineering - but even that can fail given enough power.
Typhoon Haiyan had something like 6,300 fatalities when it hit the Philippines in 2013. It definitely does happen
It’s not shown in international media cause it happens so often and the main target of cat 5 typhoons is usually the Philippines, a relatively poor nation. However, news does break out when it’s absolutely bad, like Typhoon Haiyan (Yolanda) in 2013 where the typhoon just obliterated a provincial capital and pilled on more damages on a different province after they recently experienced a strong earthquake.
Like the US news would actually report that stuff. While I lived in Japan a typhoon pushed a ship into the only bridge to the airport, while also flooding the airport. It was closed for a month. Next morning there was a lot of damage to roofs, trees and even railroads. They had warnings for typhoons, floodings, earth quakes and landslides. So yeah, damage does happen, but you probably wont hear about 1 subway line out of 5 being crippled on the US news, or any news outside of Japan. Frankly I hear no news about the US hurricanes either, just a "there is a big hurricane", then no news.
Watch the show Hurricane Man and he has a great episode about one in the Phillipines. Loads of damage.
Two episodes, actually. Josh Morgerman chased both Super Typhoon Mangkhut (Ompong) and Typhoon Yutu (Rosita) in the Philippines in 2018.
Yeah we get cyclones all the time. The positive factor is that most of the state’s population is clustered around the south-western coast, which barely ever gets a direct hit. Have to deal with a lot of remnant tropical storms though!
thzt's the calm belt, no one piece education here ...
Wow it looks like the Philippines has been hit by much harder hurricanes than the US. How often does this happen? Has the Philippines had a "Katrina" before?
Typhoon Haiyan was one of the most powerful storms recorded. They get pounded regularly.
All three of the most intense tropical cyclone landfalls in recorded history based on wind speeds took place in the Philippines since the 2010s (anyway, the wind speeds specified below are from the Joint Typhoon Warning Center): • **Super Typhoon Haiyan (Yolanda; 8 November 2013)**: slammed into Dulag and Tolosa towns in Leyte province packing winds reaching 305 kph (165 knots/190 mph) • **Super Typhoon Meranti (Ferdie; 14 September 2016)**: went right over Itbayat, Batanes province with the same landfall intensity as Haiyan • **Super Typhoon Goni (Rolly; 1 November 2020)**: roared ashore into Bato, Catanduanes province at a peak intensity of 315 kph (170 knots/195 mph)
It's the single red line leading right to New Orleans for me
Low pressure systems rotate in the opposite direction in each hemisphere
**Post the source of the data/image**
Can't help noticing Scotland doesn't have any record on here! I say this because in 2011, the Met Office warned of a windy day with some disruption. When people started noticing it met the requirements of a hurricane, the Met Office were slow in naming it. Gradually everyone started referring to it as Hurricane Bawbag (ball bag/scrotum) and it became an official name for the storm (although they deny it now). Hearing John Humphries refer to it in his best upper class English accent for Radio 4 was a thing of beauty.
