WebLife of a cyclone. Life cycle of a North Atlantic hurricane. A circulation system goes through a sequence of stages as it intensifies into a mature tropical cyclone. The storm begins as a tropical disturbance, which typically occurs when loosely organized cumulonimbus clouds in an easterly wave begin to show signs of a weak circulation. WebThe Saffir-Simpson Scale classifies hurricane-strength tropical cyclones into five categories (1-5) based on maximum sustained wind speed. Major hurricanes (also called intense hurricanes) fall into categories 3, 4, and 5 on the Saffir-Simpson Scale. A super-typhoon reaches category 4 or 5 on the Saffir-Simpson Scale.

Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth.
