When the water vapor from the warm ocean condenses to form clouds, it releases its heat to the air. The warmed air rises and is pulled into the column of clouds. ... As the moving column of air encounters more clouds, it becomes a cluster of thunderstorm clouds, called a tropical disturbance.
The main energy source of a tropical cyclone is water vapor which is abundant in the oceans and seas. When the sun heats up the earth surface, water vapor evaporates into the atmosphere and condenses into water droplets, a great amount of heat energy, which is locked up in the water vapor, is released
