FWIW: Where hurricanes/cyclones/typhoons don't happen

[usmbguest5318]

For the most part hurricanes happen everywhere except the South Atlantic and the greater Western Hemisphere of the South Pacific. The reason why is pretty straight forward: the water in those places is pretty cold.

​

Only one hurricane force storm has ever [for as long as we've been keeping track] occurred in the South Atlantic: Hurricane "Catarina" in 2004.

Hurricane Seasons:
Most Americans know when hurricanes form: summer and fall. That's about when it is for the whole of the Northern Hemisphere.

​

• EASTERN PACIFIC: The Eastern Pacific basin's hurricane season is from May 15th to November 30th, peaking in late August or early September.
• WESTERN PACIFIC: The Western Pacific basin's hurricane season is mostly from July 1 to November 30, peaking in late August or early September, though storms can occur year-round.
• SOUTH PACIFIC: The South Pacific basin's hurricane season is from October 15 to May 15, reaching a peak in late February or early March.
• INDIAN OCEAN: The Indian basin's hurricane season is from April 1 to December 31 for the northern Indian Ocean, and from October 15 to May 31 in the southern region.

Considering the fact that the scientists and weather guessers on the news are telling us that hurricanes are powered by warm water, as well as the fact that the oceans are warmer, do you think that will make hurricane season longer?

Interesting map. What's up with the West Coast of Africa that spawns nearly all the hurricanes that hit the US? It looks like there is a relatively small area that just cranks out hurricanes.

That's where the desert winds come off of the continent and starts up a tropical storm. As the storm goes over the Atlantic, it is fed by warm water and increases in strength to a hurricane.

An this lil thing called...the equator.

No, hurricanes don't start on the equator. You can see that "equator dead zone" on the map. Hurricanes need a good amount of Coriolis force to get them spinning, and that doesn't exist on or near the equator.

How do hurricanes form?


Hurricanes are the most violent storms on Earth. People call these storms by other names, such as typhoons or cyclones, depending on where they occur. The scientific term for all these storms is tropical cyclone. Only tropical cyclones that form over the Atlantic Ocean or eastern Pacific Ocean are called "hurricanes."

Whatever they are called, tropical cyclones all form the same way.




That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is less air left near the surface. ... Storms that form north of the equator spin counterclockwise.
