What is a cyclone . How is it formed?
Answers
Answer:
a system of winds rotating inwards to an area of low barometric pressure, with an anticlockwise (northern hemisphere) or clockwise (southern hemisphere) circulation.
Explanation:
• 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.
Answer:
Cyclone:-
cyclone is large,powerful and destructive storm with very high winds that turn over an area of low pressure.
How cyclones are formed:-
The whole system of clouds and wind spins and grows, fed by the ocean's heat and water evaporating from the surface.
A small low pressure system with very high speed winds revolving around it is called cyclone.
The most air over the sea and ocean gets heated by sun rays and rises up creating a low pressure region.
