Question

How does a hurricane finally die down?

Answer 1

Hint: The most important ingredient for a hurricane is the heat energy in oceanic surface water. Without its driving force the hurricane cannot survive.

Complete answer: Hurricane is an intense tropical cyclone which originates over tropical and subtropical ocean waters. The cyclones are the most violent storms on Earth. The scientific term is the storm and hurricane are large storms that develop in the Atlantic ocean or Eastern Pacific ocean. These occur as tropical cyclones. Their name varies according to the place they are born, such as typhoons, cyclones, severe tropical cyclones, severe cyclonic storms. But there are the same forces and conditions behind their occurrence. These can cause damage and devastation to life if reached land.
Warm and moist air works as fuel for the hurricane followed by wind that blows to Atalantic from Africa. Ocean water in tropical and subtropical regions is warm (creating low pressure) that causes the air to rise. The air on reaching the height cools down and condensates back to form clouds. These clouds then release heat in the atmosphere. The warm air rises and pulls up. The cycle continues and a pattern is developed. The wind starts blowing in a circle gathering a cluster of clouds. When the winds reach the speed of 74 miles per hour it is officially called a hurricane.
The hurricane dies when it loses its source of energy that means the warm water at the ocean surface. This is possible in two circumstances. First, when it reaches and blows over land. In this circumstance, the supply of driving force is absent i.e, the heat energy in the warm ocean water. The friction rises, breaking the cycle and the hurricane finally dies out. In the second circumstance, the hurricane moves towards cooler water of the ocean losing its driving force.
Thus, the hurricane dies out when there is a cut in supply of its energy source that is the warm water on the ocean surface.

Note: Keep in mind that not all ocean water works as the driving force for a hurricane. It is only the heat energy in warm water at the ocean surface that is the energy source for a hurricane.
