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 ...
The butterfly does not power or directly create the tornado, but the term is intended to imply that the flap of the butterfly's wings can cause the tornado: in the sense that the flap of the wings is a part of the initial conditions of an interconnected complex web; one set of conditions leads to a tornado, while the other set of conditions ...
This can last from a few minutes to more than an hour, and during that time a tornado often causes the most damage, and in rare cases can be more than 1.6 km (1 mile) across. The low pressured atmosphere at the base of the tornado is essential to the endurance of the system. [59]
Tornado watch: An alert signifying that weather conditions favor thunderstorms capable of producing a tornado within a certain location. People caught in a tornado watch area are urged to be prepared.
These new findings could help untangle critical questions about tornado formation and structure, how wind speeds in the air correspond to damage on the ground and the factors that can cause ...
A fire whirl, fire devil or fire tornado is a whirlwind induced by a fire and often (at least partially) composed of flame or ash. These start with a whirl of wind , often made visible by smoke , and may occur when intense rising heat and turbulent wind conditions combine to form whirling eddies of air.
Tornadoes, despite being one of the most destructive weather phenomena, are generally short-lived. A long-lived tornado generally lasts no more than an hour, but some have been known to last for 2 hours or longer (for example, the Tri-State Tornado). Due to their relatively short duration, less information is known about the development and ...
The most memorable tornado of Timmer's career came a couple of days before the historic El Reno, Oklahoma, tornado in 2013. On May 28, 2013, an intense tornado formed near Bennington, Kansas.
