Hurricanes
Hurricanes are nature's largest storms. They can last for several days or weeks. Strong winds, heavy rains, and large waves occur during these storms. Violent windstorms called tornadoes also may form over land
Hurricanes form in areas of intense low pressure and throughout their cycle can build up energy levels equivalent to 10,000 nuclear bombs. Usually occurring in each hemisphere's summer months, hurricanes are also known as cyclones or typhoons. They form over warm ocean waters when sea temperature is 26.6 degrees Celsius or higher at a depth of some 50 meters. Also, when there is enough humidity and when surface winds meet. Moreover, when warm air comes into contact with the ocean's surface it heats up and starts to rise, creating an area of low-pressure underneath. New cooler air swirls in to take its place
As the heated, moist air rises and then cools off the resulting
water vapor forms clouds. Fed by the ocean's heat and surface
evaporation the swirls of air gather pace, whipping up a storm.
Moving at about 30 kilometers an hour, generally from east to west,
the storm's diameter ranges from 300 meters to a thousand
kilometers. In just over a week, it can travel thousands of
kilometers
