How is tropical cyclone formed?

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.

What happens to tropical cyclones when they make landfall?

When a tropical cyclone makes landfall, the eye “closes”, surf gets less, and winds get less as the cyclone spreads out, losing energy. Damage inland may include flooding rains, gusty winds, and severe weather associated with the cyclone’s remnant thunderstorms. … high winds. possibly severe weather.
