During this season, copious amounts of water evaporate, rise upwards, and forms clouds. This sharply reduces the pressure directly above the sea,allowing more moisture air to flow in from the surrounding areas. Due to the rotation of the Earth 🌎, bundles of cloud start rotating and an air vortex is created. This vortex moves fast over the sea and wrecks widespread havoc on reaching the land..
