Is there a hurricane dead zone?

Dateline article| David Murphy|

Yes. In fact, there are several. While hurricanes usually form within a few degrees of the equator, they do not tend to form in the eastern Pacific Ocean, nor in the Southern Atlantic. The reason? The water in those locations is usually not warm enough to encourage the volume of evaporation and condensation needed to spark a hurricane. Also, hurricanes never form directly over the equator. This is because they need to be influenced by a force related to the rotation of the earth (known as the Coriolis Force)---and that force does not exist at the equator.
