What is a Hurricane ?

A hurricane is a severe, rotating tropical storm with heavy rains and cyclonic winds exceeding 74 miles (119 km) per hour, especially a storm which occurs in the Northern Hemisphere.
Hurricanes originate in the tropical parts of the Atlantic Ocean or the Caribbean Sea and move generally northward. They lose force when they move over land or colder ocean waters.


How hurricanes are named ?

Hurricane-like storms are called by different names in the different regions of the world.
Prior to 1979 some names were just dropped and replaced. Presently, names are picked by a committee of the World Meteorological Organization.
For example:
The name "hurricane" is given to systems that develop over the Atlantic or the eastern Pacific Oceans.
In the western North Pacific and Philippines, these systems are called "typhoons" while in the Indian and South Pacific Ocean, they are called "cyclones".


How hurricanes form?

Hurricanes only form over really warm ocean water of 80°F or warmer.
The atmosphere (the air) must cool off very quickly the higher you go.
Also, the wind must be blowing in the same direction and at the same speed to force air upward from the ocean surface.
Winds flow outward above the storm allowing the air below to rise. Hurricanes typically form between 5 to 15 degrees latitude north and south of the equator.
