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

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

[–] [email protected] 3 points 11 months ago (1 children)

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

[–] [email protected] 6 points 11 months ago (2 children)

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

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

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

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

[–] [email protected] 9 points 11 months ago* (last edited 11 months ago)

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.

So if climate change starts off some freak wave of endless hurricanes… move to the equator got it

[–] [email protected] 54 points 11 months ago

Yes, you will be safe from hurricanes while you are baked alive by global warming.

[–] [email protected] 23 points 11 months ago

Well, unfortunately it'll become a blistering hellscape.

[–] [email protected] 8 points 11 months ago (2 children)

Well, it might fuck up the wind currents and allow even bigger storms that could cross the equator

[–] [email protected] 9 points 11 months ago (3 children)

I thought the issue was the coriolis effect would reverse the hurricane's spin direction? Could one survive this and reform?

[–] UrPartnerInCrime 3 points 11 months ago

Give it a couple decades and we may just find out!

At least until the magnetic poles flip and then all hell breaks loose (again).

[–] [email protected] 19 points 11 months ago

It's like a reverse Grand line

[–] [email protected] 18 points 11 months 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

I believe it’s because currents of air rotate in the opposite direction. So to cross the equator the air would have to pass a boundary of global air currents which are going counter to the hurricane’s motion. See this picture for a reference.

[–] [email protected] 21 points 11 months ago (3 children)

I knew it. Hurricanes are magnetic.

[–] [email protected] 15 points 11 months ago

Fuckin hurricanes, how do they work?

[–] [email protected] 8 points 11 months ago* (last edited 11 months ago)

Trump should've bombed Hurrican Dorian with ICP instead.

So the thing about the toilet water spinning in the other direction in the south hemipshere is true?

[–] [email protected] 7 points 11 months ago

No - the direction the toilet water spins depends on the small scale vortices created when you flush. The Coriolis effect is slow - it acts at a much longer time scale.

[–] [email protected] 4 points 11 months ago

In theory, yes. However other factors such as the shape of the drain, the shape of the toilet bowl, and any small initial motion in the water, usually completely overwhelm the coriolis effect. You would only be able to observe it under extremely carefully controlled conditions: extremely still water, and a completely symmetrical toilet bowl perfected to extreme, micron precision.

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 19 points 11 months 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.

[–] [email protected] 6 points 11 months 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.

So we wanna live in South America, got it

[–] [email protected] 6 points 11 months ago* (last edited 11 months 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.

[–] [email protected] 3 points 11 months 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.

[–] [email protected] 9 points 11 months ago (4 children)

Seems like the equator would make a perfect location for a wind farm. Looking at this map that was posted above, just have rows and rows of them that follow the equator.

[–] [email protected] 6 points 11 months ago

The equator doesn't have strong wind though? And what does that map of ocean currents have to do with that?

[–] [email protected] 4 points 11 months ago (3 children)

What's the farthest we can transport electricity? Seems like that may be pushing the boundary a bit. I wonder if it would be possible to have a world-wide electricity grid.

[–] [email protected] 4 points 11 months ago

Yes absolutely, feasible is another thing but possible it absolutely is. There already exist worldwide conductor networks.
