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 ...

How do tornadoes work? Tornadogenesis is a word used to describe the formation process of a funnel. Bruce Thoren, a forecaster at the National Weather Service, said that this process is still not ...
For a tornado to form in this manner, a rear-flank downdraft enters the center of the mesocyclone from the back. Cold air, being denser than warm air, is able to penetrate the updraft. The combination of the updraft and downdraft completes the development of a tornado. Tornadoes that form in this method are often violent and can last over an ...
Severe tornado damage occurs with an EF3 tornado, which has wind speeds of 136 to 165 mph. Some walls of well-constructed houses can be torn off. Most trees in the path of the twister will be ...
