Formation of cyclones write at least 3 points.

Answer:-
Even though they form over different areas, cyclones tend to come about in the same way and revolve around that low-pressure eye. Warm air likes to rise, and as it rises, it cools. Cool air can't hold as much moisture as warm air, so that water gets squeezed out of the condensing air and a cloud begins to form. If the warm air rises very quickly, this creates an updraft.
Likewise, if the water in the cloud builds up enough, it may fall back to the ground as rain and draw cool air down with it as a downdraft. When they work together, that warm updraft and cool downdraft create a storm cell. As this process continues, the cloud grows and we eventually get a large thunderstorm cloud.
This thunderstorm cloud is now ready to diversify into other storms like tropical cyclones and tornadoes. But this can't happen unless the air in the cloud starts spinning horizontally. If this occurs over the tropical ocean, this is called a tropical depression. This is like a baby tropical cyclone, with wind speeds less than 39 mph.
If it starts spinning even faster and has wind speeds between 40-73 mph, we have a tropical storm. If the storm grows even larger over the tropical ocean and has wind speeds above 74 mph, we have our full-grown hurricane, typhoon or cyclone, depending on where that storm is found.
✧Formation of Cyclones
The important contributors of cyclone formation are wind speed, wind direction, temperature and humidity. Let us understand how a cyclone is formed.
- water from Seas and oceans evaporates due to Sun's heat
- On reaching a cool and higher altitude, water vapour release the heat and condenses to form cloud. The heat that is released hits of the surrounding air.
- This warm air moves for the up, creating a low - pressure region. To compensate for the difference in pressure, more air rushes towards this region.
- Due to the spinning of the Earth, the air rushing of word move in circles. Therefore, a cyclone, Central low - pressure region surrounded by high - speed - swirling wind, is formed .
