These comprise spiralling winds that are usually centred in areas that have low atmospheric pressures. At the same time, they are surrounded by high pressure.They usually occur in tropical regions due to high temperature and humidity. Cyclones are referred to as typhoons in the Pacific Ocean, cyclones in the Indian Ocean and hurricanes in America. About 65-75 cyclones arise in the world every year.
