Tropical refers to the geographical regions, and the term cyclone refers to such storms of cyclonic nature, with counterclockwise wind in the Northern Hemisphere, and clockwise in Southern Hemisphere - this opposite movement of the wind is because of "Coriolis Force". Depending upon the location and strength, a tropical cyclone is referred to by names such as hurricane, typhoon, tropical storm, tropical depression, cyclonic storm, or simply cyclone. While tropical cyclones can produce extremely powerful winds and torrential rain, they are also able to produce high waves, damaging storm surge, and tornadoes. They develop over large bodies of warm water, and lose their strength if they move over land due to increased surface friction and loss of the warm ocean as an energy source. This is why coastal regions can receive significant damage from a tropical cyclone, while inland regions are relatively safe from receiving strong winds. Heavy rains, however, can produce significant flooding inland, and storm surges can produce extensive coastal flooding up to 40 kms (25 mi) from the coastline. Although their effects on human populations can be devastating, tropical cyclones can relieve drought conditions. (2) A wind of Force 12 on the Beaufort, above 118 km / ph is also called a Hurricane, irrespective of the origin or location. Tornadoes
