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 ...
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 tornado generating storms were often welcomed by colonial settlers in the region since they dissipated extreme heat and humidity during the last days of the dry season. Tornadoes are often embedded in the African squall lines, [30] [31] but they damage crops, and diminish any beneficial effect of its rains.

Strong mesocyclones show up as adjacent areas of yellow and blue (on other radars, bright red and bright green), and usually indicate an imminent or occurring tornado. The history of tornado research spans back centuries, with the earliest documented tornado occurring in 200 and academic studies on them starting in the 18th century. This is a ...
These tornadoes may form at different times or exist simultaneously but are separate from one another. A phenomenon similar to multiple vortices is the satellite tornado. Unlike the multiple-vortex tornado, where smaller vortices form inside the main tornado, a satellite tornado develops outside the main tornado's circulation.
