A typhoon is a mature tropical cyclone that develops in the northwestern part of the Pacific Ocean between 180° and 100°E. This region is referred to as the northwest Pacific basin. It is common in the China Sea. Hurricanes are common on the east coast of the North America and the adjoining islands. In meteorology, a cyclone is an area of closed, circular fluid motion rotating in the same direction as the Earth. It is common in the Indian Ocean. A tornado is a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. They are often referred to as twisters or cyclones. Tornadoes have been observed on every continent except Antarctica. However, the vast majority of tornadoes in the world occur in the so-called “Tornado Alley” region of the United States.
