Question

how does a thunderstorm become a cyclone

Answer 1

As, we know that heat is required to change the state of water from liquid to vapours. Before forming clouds water absorbs moisture and heat from the atmosphere to change to the vapour state. During rain and thunderstorms, it releases heat and gets cool, due to which it rains. The released heat causes the air to become warm, due to which it rises up. This causes a pressure drop. So, cool air rushes to take its place. This causes formation of low-pressure belt around that area. The air now moves at a great speed to fill the pressure gap. This causes formation of cyclones.
