What occurs between 5-30º latitude?
Tropical storms.
What three conditions are needed for a tropical storm to occur?
Ocean surface temperatures need to be at least 27ºC, low wind shear, and the Coriolis effect allow a tropical storm to form.
What time in the year will a tropical storm usually form?
Tropical storms usually form in the Summer and Autumn.

The winds travel to the left.
In what hemisphere do winds travel to the right?
The Northern Hemishpere.
In what hemisphere do winds travel to the left?
The Southern Hemisphere.
Why do winds curve near the equator?
As the equator spins faster than the rest of the world.
