Hurricanes

What are Hurricanes?

Hurricanes are enormous storms which come with rotating wind speed of 74 miles per hour. The rotating wind swirls across the warm water of the tropics and comes with terrifying force. This force blast ashore which causes destruction and even death. Hurricanes are known to be one of the nature’s most destructive storms as they bring heavy rains, deadly waves and fierce winds. Hurricanes leave its mark by hitting the land, rip up trees, cause floods and destroy homes. Thousands of people get killed with this terrifying storm and cause million dollars of damage. People get homeless, everything gets swept away by these floods. Another violent windstorm is known as Tornadoes. Tornadoes winds are more violent and stronger than hurricane winds. Hurricanes last longer and cover up to 500000 square miles of land.

How do Hurricanes form?

Hurricanes are known to be the most violent storms on earth. Usually, they are formed near the equator over the warm ocean water. Waves are produced when oceans are at their warmest temperature and the air above water becomes heavy with a lot of moisture. Hurricanes typically form between 5 to 15 degrees latitude north and south of the equator.

The period during each year when hurricanes are most likely to occur in a given place is called as hurricane season. Hurricane season lasts from June to October over the Western Pacific and in Atlantic, it runs from June to November.

Tropical Cyclone A generic term for any organized low pressure that develops over tropical and sometimes subtropical waters. Tropical depressions, tropical storms, and hurricanes are all example of tropical cyclones.
Tropical Depression An organized area of low pressure in which sustained winds are 38 mph or less.

Hurricane
