Well duh! That's because the big black line you see on all the maps keeps the storms from crossing over

Make the north hemisphere great again!

For anyone else wondering about that single path near the southern part of Brazil: https://en.m.wikipedia.org/wiki/Hurricane_Catarina

[-] marcos@lemmy.world 25 points 2 years ago

They could add 2 more if they updated the map into this year.

[-] Cornpop@lemmy.world 4 points 2 years ago

What 2? According to the wiki this is still the only one on record.

[-] Phen@lemmy.eco.br 7 points 2 years ago

We had two cyclones in the last two/three months.

[-] Cornpop@lemmy.world 2 points 2 years ago

I don't think they were strong enough to be considered hurricane strength like Catarina. It's the only one on record.

[-] Phen@lemmy.eco.br 4 points 2 years ago

They were stronger than usual (we actually had several cyclones this year if we count all of them) so I'm assuming that's what OP referred to. I still slept through one of them without even noticing it so nowhere as strong as Catarina.

This month's winds reached 2/3 the speed of Catarina.

Well that is super interesting. Was wondering if that was a visual artifact.

Note to self: To avoid hurricanes, move to the equator.

[-] Aussiemandeus@aussie.zone 40 points 2 years ago

Thats because when they come south of the equator they become cyclones

Yeah they shouldn't have any color like that in Asia. They only get Typhoons.

Dont k ow wtf just happened, but when i looked at that map, it was wrong. I think it was flipped upside sown and zoomed in, but the coloured bits were the right way up and not zoomed.

I could not figure out the shape of the earth, couldnt see any continents i recognized. When i saw what i assumed was Antarctica at the top, i assumed the map was flipped, but i still couldn't find any countries.

I saw a comment about a single line near brasil, and when i saw it, it was on the land.

I scrolled further and found a map with arrows suowing the circular motion of the winds and when i went back up the map was flipped the correct way, zoomed out and the single line was off the coast of brasil.

But obviously thats not possible so i just had another look and realised. I saw the land as water and the water as land. It switched when i looked away and now i cant switch it back.

This was trippy as hell.

[-] June@lemm.ee 1 points 2 years ago

Oh shit i read your comment and went back up and could switch to see it that way. Fuck that’s weird.

[-] joel_feila@lemmy.world 18 points 2 years ago

A tropical disturbance has crossed the equator. One such disturbance occurred June 27, 2008 in the Atlantic basin (south to north) that retained its clockwise motion for some time:

So not completely impossible

[-] Jaytreeman@kbin.social 18 points 2 years ago

It's like a reverse Grand line

Coriolis effect. Things spin opposite direction across the equator due to how the earth spins.

It’s virtually impossible for a hurricane to cross the equator.

[-] captain_aggravated@sh.itjust.works 19 points 2 years ago

Because of things like Coriolis effect and convective currents, there just aren't winds that blow across the equator, not at the scale that would blow a hurricane from one hemisphere to the other anyway.

Winds tend to blow along and away from the equator, not across it.

[-] mierkxiii@lemmy.world 7 points 2 years ago

For ELI5, think of it this way. The earth is spinning, and at the equator it's moving really fast, like 900 mph. At the north pole, the earth isn't moving at all, so in the northern hemisphere, you can picture all land to the north of you as moving slower than you, and land to the south as moving faster than you. If you run south, it would spin you because it's moving 'sideways' faster than you are. Cross the equator and suddenly it gets slower as you run south, literally putting the brakes on your spin.

[-] ChicoSuave@lemmy.world 4 points 2 years ago

The ancient city of R'yleh is rumored to be somewhere along the equatorial line. In ancient times was known as the torrid zone, an infernal place which claimed all the lives of those that cross it. Hurricanes are a force of nature and, since no two forces of nature can overlap (like a volcano during a storm or an earthquake and a flood) the hurricane can't go where ancient ones dwell.

[-] remotedev@lemmy.ca 11 points 2 years ago

So we wanna live in South America, got it

[-] Decoy321@lemmy.world 6 points 2 years ago* (last edited 2 years ago)

Nah, dude. If you want to avoid hurricanes, you gotta go to Antarctica. Just look at the map, it's just got cool blue arrows.

[-] Phen@lemmy.eco.br 3 points 2 years ago

I recommend Uruguay, specifically. That little country is miles ahead of the rest of the continent in several aspects.

Or, if you are American and wealthy enough to own a house (in the USA), you're likely wealthy enough to buy a good house in Brazil and retire with enough passive income to ignore all of this country's problems.

Way to jinx it.
