A tornado is a violently rotating column of air in contact with the surface and a cumuliform cloud base. Tornado formation is caused by the stretching and aggregating/merging of environmental and/or storm-induced vorticity that tightens into an intense vortex. There are various ways this may come about and thus various forms and sub-forms of ...
Tornadoes can occur anywhere in the U.S., according to the National Weather Service.Tornadoes are “most common in the central plains east of the Rocky Mountains and west of the Appalachians.”
Tornadoes occurring in these conditions are especially dangerous, since only weather radar observations, or possibly the sound of an approaching tornado, serve as any warning to those in the storm's path. Most significant tornadoes form under the storm's updraft base, which is rain-free, [36] making them visible. [37]
They are most common in the middle latitudes where conditions are often favorable for convective storm development. The United States has the most tornadoes of any country, as well as the strongest and most violent tornadoes. A large portion of these tornadoes form in an area of the central United States popularly known as Tornado Alley. Canada ...
Some of the most notorious twisters in U.S. history were wedge tornadoes, including the EF5 that leveled Joplin, Missouri, on May 22, 2011, and the El Reno tornado, which was a jaw-dropping 2.6 ...
How do tornadoes work? ... However, TOTO's center of gravity was too high to stand upright in storms, rendering it unusable, according to NOAA. The closest use of TOTO to an actual tornado was ...
How do tornadoes form? These vicious columns of air are formed from severe thunderstorms, which swoop close to the ground. The main ingredients to a tornado are warm air and cool air.
A tornado family is a series of tornadoes spawned by the same supercell thunderstorm. [1] These families form a line of successive or parallel tornado paths and can cover a short span or a vast distance. Tornado families are sometimes mistaken as a single continuous tornado, especially prior to the 1970s.
