Whenever whirlpools are formed in the atmosphere due to specific wind masses, it is called a cyclone. Cyclones are the deadliest of atmospheric disasters! These are areas of low pressure, around which lines of rising air pressure are found! In this, the air pressure gradually increases as we move from inside to outside.
Therefore, the speed of wind is transmitted from the periphery to the centre, whose direction is anticlockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere! Their shape is circular, elliptical or similar to "V". Cyclones are considered important from the point of view of weather and climate because at the place where they reach there is a sudden change in the amount of rainfall and temperature.
Facts About Cyclone
Cyclones are the most dangerous natural hazard to people.
The early or weak phases of a cyclone are called tropical depressions.
Cyclones that occur in the Atlantic and Northeast Pacific are called hurricanes.
A cyclone in the North West Pacific is called a typhoon.
The low-pressure centre of a tropical cyclone typically marks an area of "surprisingly calm" from 32 to 64 km wide.
When Meteorologists see that a new tropical cyclone has formed, they give it a name so that the people affected by the storm issue forecasts and warnings.
Cyclones can occur throughout the year in the Southern Hemisphere. The most common time for them is the end of February and the beginning of March.

Cyclones are one of the most dangerous natural hazards that can cause many destructions in the environment. It can be circular, elliptical as well as in V shape structure. Generally, it can create bad effects on us. In this article, we have studied many important facts about Cyclones. Now we know the meaning, facts and much more about cyclones.
