Hurricanes form by having warm air rising and cool air sinking, then air with a higher air pressure from another area moves into the lower air pressure and makes ¨new¨ air and turns into warm and moist air that rises. AS the warm air rises, surrounding air swirls in to take its place. Once the warm air rises into the atmosphere it condenses and turns into clouds. Then the clouds and winds spin, grow and keep collecting power from the warm moist ocean water evaporation.
Hurricanes can only form over tropical sea waters with the surface as about 80* F.
Hurricanes go in a counter-clockwise rotation around the ¨eye¨. The storm consists of air spiraling upwards and inwards.
They include Cumulonimbus clouds and Cirrus clouds. The wind speeds can be 75-200 miles per hour. When a hurricane touches land it gives heavy rain, big waves, and destruction. One of the worst records of a hurricane was in 1780, in the Caribbean sea. It struck Jamaica on October 3rd. It almost wiped out the town Savannah La-Mar, and some 200 people were lost. Another Hurricane was on August 29th to September 9th in 1775. It affected North Carolina, Virginia, and Newfoundland. It killed about 4000 people and more. For comparing, they both made a lot of destruction, and for contrasting more people died in 1775 than 1780.
People have prevented damages and deaths from hurricanes by, recording data on a weather maps and warning the people in that area to leave, so they do not die.
