Question

how cyclone is formed?

Answer 1

Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is less air left near the surface.

Answer 2

$\textbf{Cyclone}$:

A small low pressure system with very high speed winds revolving around it is called cyclone.

$\textbf{How Cyclones Forms ? }$

The most air over the sea and ocean gets heated by sun rays and rises up creating a low pressure region. This warm air get cool and starts condensing.

During condensation heat is released and air around it gets warm. This warm air rises upwards creating a low pressure region.

This space is filled by cooler air. This cycle of events continue till a very low pressure system with very high speed winds revolving around it is formed. This forms cyclone.
