How does hurricanes form
andrew-mc [135]
Winds flow outward above the storm allowing the air below to rise. Hurricanes typically form between 5 to 15 degrees latitude north and south of the equator. The Coriolis Force is needed to create the spin in the hurricane and it becomes too weak near the equator, so hurricanes can never form there. So basically, when air rises and starts to spin, it creates a hurricane.
