Formation of a Hurricane

In tropical areas, where there is at least waters of eighty degrees fahrenheit, or twenty seven degrees celsius, is where hurricanes form. There has to be moist air and have converging winds. Most of the hurricanes that occur in the Atlantic begin of the west coast of Africa. They start as thunderstorms that move out over warm, tropical ocean waters. There are three stages for a thunderstorm to become a hurricane. The first stage is a tropical depression, which has swirling clouds and rain and has wind speeds of less than 38 miles per hour. Then a tropical storm occurs with wind speeds of 39 to 73 miles per hour. Finally the hurricane begins with winds over 74 miles per hour. The developement of a hurricane can take anywhere from hours to days to form. Other steps in the fomation a of a hurricane are:

Warm, moist air from the ocean rises rapidly.

Water vapor condenses and builds storm clouds and rain droplets.

Condensation releases heat called latent heat of condensation.

Latent heat warms the cool air, causing it to rise.

Then, the rising air is replaced by more warm, humid air from the ocean.

This cycle continues, and circling winds form.
