Answer:- In meteorology, a cyclone refers to any low pressure area with winds spiralling inwards. Cyclones rotate clockwise in the Southern Hemisphere and anti-clockwise in the Northern Hemisphere. ... Cyclones are also referred to as hurricanes and typhoons. They consist of the eye, eyewall and rainbands.
Causes:-
• Tropical cyclones form only over warm ocean waters near the equator.
• To form a cyclone, warm, moist air over the ocean rises upward from near the surface. As this air moves up and away from the ocean surface, it leaves is less air near the surface. So basically as the warm air rises, it causes an area of lower air pressure below.
• Air from surrounding areas with higher air pressure pushes in to the low pressure area. Then this new “cool” air becomes warm and moist and rises, too. And the cycle continues…
• As the warmed, moist air rises and cools the water in the air forms clouds. The whole system of clouds and wind spins and grows, fed by the ocean’s heat and water evaporating from the ocean surface.
• As the storm system rotates faster and faster, an eye forms in the centre. It is very calm and clear in the eye, with very low air pressure. Higher pressure air from above flows down into the eye.
cyclone are violent storms with an intense apiral and accompained by strong wind and heavy rain .They are caused due to strong wind blowi g around the central areas having lower atmospheric pressure
causes
factors affecting cyclone
factors like wind speed wind direction
temprature and humidity contribute the development of a cyclone the center of the cyclone is cloudless arm area thats called eye.In this area wind are not very strong and there is no rainfall.
