Answer:

Cyclones are also termed as atmospheric disturbances. They range in shape from circular, elliptical to ‘V’ shape. When the velocity of winds increases to such an extent that they attain gale force, the atmospheric disturbance or cyclone is called a cyclonic storm.

Cyclones are centres of low pressure surrounded by closed isobars having increasing pressure outward and closed air circulation from outside towards the central low pressure in such a way that air blows inward in anticlockwise in the northern hemisphere and clockwise in the southern hemisphere.

A tropical cyclone is a low-pressure system which develops in the tropics and is sufficiently intense to produce sustained gale force winds of at least 63km/h. If the sustained wind reaches hurri­cane force of at least 118km/h the system is defined as a severe tropical cyclone. In other parts of the world they are called hurricanes or typhoons.

Answer:

The word ‘Cyclone’ is derived from the Greek word ‘Cyclos’ a circle which means whirlwind. Generally, cyclone means a kind of moving storm. It always changes its direction and blows at the rate of 60 kilometers or more per kilometer. When very strong winds whirling around the center of the storm moving at a terrific speed with an anti-clockwise motion in the northern hemisphere and with a clockwise motion in the southern hemisphere, a cyclone occurs. This depression prevails on the ocean first. Then it gradually proceeds with much speed towards the land. The region that it touches becomes dark. The sky becomes cloudy. The flow of wind begins suddenly and the temperature rises. Such an environment forecasts that a cyclone is going to take place. Soon the sound of the wind becomes as loud as the roaring of a lion. Rains begin to pour in torrents with flashes of lighting and thunder this is all about cyclone i know
