What are the factors for the formation of cyclone?

There are six factors responsible for the formation of the cyclone: (1) Sufficient warm temperature at sea surface (2) atmospheric instability (3) impact area of Coriolis force so that low pressure can be developed (4) high humidity in the lower to middle levels of the troposphere (5) a pre-existing low-level focus or …

Why do tropical cyclones form?

Oceans and seas have great influence on the weather of continental masses. … These water evaporated from the sea/ocean is carried up into the atmosphere and condenses, forming clouds from which all forms of precipitation result. Sometimes, intense cyclonic circulations occur which is what we call the tropical cyclones.

What is a tropical cyclone and how is it formed?

Tropical cyclones are formed only over warm ocean waters near the equator. When warm, moist air over the ocean rises upward from near the surface, a cyclone is formed. When the air rises up and away from the ocean surface, it creates an area of lower air pressure below.
