Tornadoes often develop from a class of thunderstorms known as supercells. Supercells contain mesocyclones, an area of organized rotation a few miles up in the atmosphere, usually 1â6 miles (2â10 km) across. Most intense tornadoes (EF3 to EF5 on the Enhanced Fujita Scale) develop from supercells.
This type of tornado is formed above the surface of water. There are two types of waterspout tornadoes-tornadic and non-tornadic or fair-weather. Tornadic waterspouts are mesocyclonic tornadoes that are formed over the surface of water.ype 1 tornadoes form from the mesocyclone of a thunderstorm, usually a supercell. These tornadoes usually â¦ have winds under 110 mph, but in some cases winds can exceed 300 mph. Type 2 tornadoes, which include landspouts and most waterspouts are weaker.
