How do cyclones form ?
Very damp, hot air rises rapidly from the surface of the sea ,meeting cold air high in the atmosophere.This air condenses to from clouds and rain , condensation also releases energy producing strong winds. These winds driven by the speed of the earth twist round and round and are sucked upward rotating in a vortex . This is how a cyclone is formed .
