What causes tornadoes?

Answer 1

A fire tornado is caused by a dry land area. when a fire is sparked, and there is the right wind currents a spiral is formed and causes a tornado of fire. conditions for fire tornadoes can be caused by wind whipping through trees and thus creating a circular air flow motion making a spiral.

Answer 3

Sort of. There are whirlwinds called firewhirls. They look somehwat like tornadoes and are sometimes called "fire tornadoes," but they technically are not tornadoes. In their dynamis they are mor like dust devils.

Answer 4

Tornadoes are caused by the interaction of weather systems, which create large thunderstorms (the most powerful and long-lived type is called a supercell). The winds created by the growth and motion of these storms may create vortices (funnel clouds) that can descend to reach the ground, and move along the ground as tornadoes.

The formation of tornadoes is complicated.

First, you need thunderstorms, then you need a condition called wind shear, in which the speed or direction of the wind changes with altitude. If the shear is strong enough it can essentially tilt a thunderstorm. This separates the updraft and downdraft of the thunderstorm, preventing them from interfering with one another. This allows the storm to become stronger and last longer.

Additionally, if the wind shear is strong enough it can start the air rolling in what is called horizontal vorticity. This horizontal vorticity can then be turned vertical by a thunderstorm's updraft. When this happens, the thunderstorm may start rotating. The rotation is especially strong in an updraft called a mesocyclone. If the storm intensifies rapidly enough, a relatively warm downdraft called a rear-flank downdraft or RFD can wrap around the bottom part of the mesocyclone. This can then tighten and intensify its rotation and bring it down to the ground to produce a tornado.

Answer 5

Most likely "fire tornadoes" form by a mechanism similar to dust devils. The hot air produced by a fire creates and updraft and more air must move in to replace it. Interaction with vegetation, buildings, local topography, and the wind can sometimes give this in-rushing air a spin. The updraft then takes on this spin ant pulls it into a tight and intense vortex.

Answer 6

"Fire tornadoes" more properly called firewhirls form when wind currents start rotating due to interaction with the terrain. The updraft created by the fire then takes on this spin to form a firewhirl.

Answer 7

See the related question for what causes tornado in general.

Tornado outbreaks typically occur when a mid-latitude low pulls in warm, moist air from the south, and cooler and/or drier air from the north, the creates either a cold front, a dry line, or both. In either case the result is strong thunderstorms. If enough wind shear is present these a number of these storms can become supercells and produce tornadoes. Additionally, one supercell can produce several tornadoes one after the other.

Answer 8

In the case of tornado outbreaks, if conditions are favorable for tornadoes, chances are that more than one storm will produce them.

Multiple tornadoes close together most often occur in a tornado family. A tornado family occurs when a thunderstorm goes through cycles produces multiple tornadoes in succession. In some cases one member of a tornado family forms before the previous one dissipates. Winds flowing into a large, intense tornado may sometimes spawn a smaller satellite tornado that revolves around it.

Finally, it is possible for a single tornado to have more than one funnel. Such multiple-vortex tornadoes occur when a downdraft descends through the center of a tornado. When it reaches the ground and spreads out it collides with air flowing into the tornado, producing complex interactions that spawn smaller vortices inside the main circulation.
