This means that the air aloft is significantly cooler than the warm, rising parcel of air from the ocean. These disturbances act as the "seed" or focal point around which the hurricane can organize.

Without this instability, the rising air would cool, become denser, and sink back down, effectively stifling the development of the cyclonic structure. Additionally, the upper-level winds in the atmosphere must be relatively calm.
Hurricanes require a minimum distance of roughly 5 degrees of latitude from the equator, where the spin of the planet can effectively organize the thunderstorms into a rotating vortex. Near the equator, the Coriolis force is too weak to initiate the rotation necessary to form a cyclonic circulation.

The heat causes moisture to evaporate rapidly from the ocean surface, rising into the atmosphere where it eventually condenses into clouds and rain, releasing latent heat that further lowers the air pressure at the surface. When this condition is met, the rising air continues to rise on its own, allowing the system to grow vertically and organize into thunderstorms.
