What causes typhoons? What "builds up" to make one?

Question

Is there a certain wind involved?

Answer 1

Tropical cyclones are also known as hurricanes, typhoons, tropical storms, cyclonic storms, and tropical depressions - depending on location and strength.

A tropical cyclone is a warm storm system fueled by thunderstorms near its center. It feeds on the heat released when moist air rises and the water vapor in it condenses, which makes them "warm core" storm system.

The storm's origin is in the tropics and its cyclonic in nature, which means that its circulation is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

Tropical cyclones can produce extremely strong winds, tornadoes, torrential rain, high waves, and storm surge. They are born and sustained over large bodies of warm water, and lose their strength over land.

They carry heat away from the tropics, which is an important mechanism of the global atmospheric circulation that helps maintain equilibrium in the Earth's troposphere.

Answer 2

Starting from tropical waves (this gives a disturbance in the mean wind field) typhoons build up when they have warm waters, warm moist air to digest, and must be at least 5 degrees from the equator in order to have enough spin (provided by the Coriolis force...an apparant force resulting from the Earth's rotation).

Answer 3

When a cold air mass forms and moves across the warm waters of the ocean

Answer 4

Air pressures.
