Question

explain the formation of a cyclone.
with a neat labelled diagram.

Answer 1

Before the formation of clouds, water takes up heat from the atmosphere to change into vapour. When water vapour changes back to water form as raindrops, this heat released to the atmosphere warms the air around. The air tends to rise and causes a drop in pressure. More air rushes to the centre of the storm. This cycle is repeated. The chain of events ends with the formation of a very low pressure system with very high speed winds revolving around it. It is this weather condition that we call a cyclone. The factors like wind speed, wind direction, temperature and humidity contribute to the development of a cyclone.

Answer 2

hi Shaurya,

here is your answer


FORMATION OF A CYCLONE
~~~~~~~~~~~~~~~~~~~~~~~~~~


Violently rotating high speed winds with severe rains are called CYCLONE.



The formation of a CYCLONE depends on the speed and direction of the wind, temperature and humidity.

1.........
When the warm air rises, it cools, condenses and forms clouds. When the water vapour is formed, it takes heat from the surrounding atmosphere.

2........
When the water vapour in the clouds turns into rain drops, the heat possessed by the water vapour is released into the atmosphere.

3........
This causes more air from the surrounding to rush in. This causes further decrease in the air pressure of that area.

4......
The above process repeats and the release of heat from the water vapour continues. This results in the formation of a very low pressure system surrounded by very high speed whirling winds.

THIS IS HOW A CYCLONE IS FORMED...
