The three types of cyclones are tropical cyclones, polar cyclones and mesocyclones. In general, a cyclone is a weather system of low pressure that is surrounded by a rotating storm. The location of the developing storm is a primary factor for determining the type of cyclone.
Most commonly known as hurricanes or typhoons, tropical cyclones form over warm oceans. A hurricane manifests in the Atlantic or Northeast Pacific Ocean, while a typhoon develops in the northwest areas of the Pacific Ocean. Polar cyclones develop over frigid areas located close to the Earth's North and South Poles. Finally, mesocyclones materialize when areas of low pressure and high pressure converge over the ground and create a vortex. This type of cyclone is known as a tornado.
