FORMATION OF CYCLONE Refers: It refers to any spinning storm that rotates around low air pressure called as Cyclone. Low Air Pressure: When the moist air move rise from water surface that particular area called as low air pressure. FORMATION OF CYCLONE: In order for a Cyclone to form it requires two ingredients: 1. Thunderstorm and 2. Ocean water must be above 26 degree centigrade. When the temperature of water above 26 degree centigrade, water evaporates, this moist air rises above the water surface to form clouds. That particular area becomes low air pressure, we know that higher air pressure always moves towards low air pressure. Surrounding to that area, higher air pressure moves towards low air pressure and this cool air become warm and evaporates, this system continuous. When the high pressure air moves along the earth axis, it makes clouds to rotate with high wind. These all combines to form cyclone.
