Answers
Answer:
A cyclone is a general term for a weather system in which winds rotate inwardly to an area of low atmospheric pressure.
For large weather systems, the circulation pattern is in a counterclockwise direction in the Northern Hemisphere and a clockwise direction in the Southern Hemisphere.
Types of cyclones include tropical cyclones, extratropical cyclones and tornadoes.
A tropical cyclone is a rotating low-pressure weather system that has organized thunderstorms but no fronts. They form over warm ocean waters.
Tropical cyclones with maximum sustained surface winds of less than 39 mph are called tropical depressions. Those with maximum sustained winds of 39 mph or higher are called tropical storms. When a storm’s maximum sustained winds reach 74 mph they are called hurricanes or typhoons. Hurricanes form over the Atlantic Ocean or Caribbean Sea; typhoons form over the western Pacific Ocean.
The cyclones are irregular wind movements involving closed air circulation around a low pressure centre. This closed air circulation is caused by atmospheric disturbances over and above the earth’s surface, coupled with the earth’s ‘rotation which imparts to these disturbances a whirling motion.

The cyclones level down inequalities of pressure and wind movement over the globe. They play an important role in the complex process of heat exchange between various latitudinal zones. Cyclones have a bearing over the phenomenon of precipitation, especially in mid-latitude regions, by lifting up the moist air from oceans and taking it into the surrounding landmasses.
