how does thunderstorm become cyclone?
We know that when the water changes its state, heat is evolved.
So,
Before cloud formation, water takes up heat from the atmosphere to change into vapour. When water vapour changes back to liquid, in the form of rain drops, this heat is released in to the air, thus heating the surrounding air. Now this warm 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 results in the formation of a very very low pressure system with high speed winds revolving around it. It is these weather conditions which are called a cyclone.
