Explain the formation of cyclone

Dear Student

Cyclone is formed above a warm area, usually warm sea.
When the area becomes warm the hot air in contact with the area rises and pressure in that area falls.
This fall in the pressure lets surrounding cold air having high pressure to rush in the region of low pressure. 
At the warm region, the warm, lighter air rises gently over the heavier cold air, which being heavy stays close to the ground.
As the warm air rises, it cools, and the moisture present in it condenses to form clouds.
This rain falls steadily for a few hours to a few days.
This sometimes forms a vortex which means the air flow inside with a circular manner.
It is the Earth’s rotation and spinning on its axis that causes the cyclone’s clouds to rotate. This generates cyclones.
