Cyclone is formed naturally over the sea by the heavy and circular, flow of storm. When air of a particular area of upper surface gets heated, it goes upward, thereby creating low pressure area. Air from with high pressure moves to fill the air gap of the low pressure area. If this movement is very fast, it takes the shape of a cyclone. Center of the cyclone is called the eye of the cyclone. The radius of the eye is near about 10 to 30 km. The eye of the cyclone is free from clouds. The strength of the cyclone decreases on moving towards the earth surface.
