Hurricanes and Tropical Storms
... The key energy source is the latent heat that's released when water vapor condenses into cloud droplets and rain. Tropical storms and hurricanes grow best in a deep layer of humid air that supplies plenty of moisture. When a solid substance changes phase, energy must be supplied in order to overcome ...

Atmospheric convection
Atmospheric convection is the result of a parcel-environment instability, or temperature difference, layer in the atmosphere. Different lapse rates within dry and moist air lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes.
