The formation of tornadoes is complicated.
First, 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.
What else can I help you with?
Are tornadoes man made?
No. Tornadoes occur naturally.
Why are tornadoes made of air?
Tornadoes are made of air necause they are a weather phenomenon and occur within Earth's atmosphere, which is made of air.
Are there such things like double tornadoes?
There are multivortex tornadoes that at times can look like they are made up of two or more tornadoes
What are tornadoes made of fire called?
Tornado-like whirlwinds made of fire are called firewhirls. Meteorologists do not consider them to be true tornadoes.
Are tornadoes made from electricity?
No. Tornadoes are made from interactions of wind currents and pressure differences within a thunderstorm. Electricity plays no role.
How is earth affected by tornadoes?
Tornadoes can cause catastrophic damage to vegetation and man-made structures.
What kind of gases do tornadoes produce?
Tornadoes do not produce gasses. They are made of air and do not change its composition.
Has there ever been a water tornado?
There are no tornadoes that are made of water, but tornadoes do touch down on water fairly often. Tornadoes on water are called waterspouts.
Are tornadoes natural or man made?
Tornadoes are storms, and thus naturally occurring.
What are the impaets of tornadoes?
Tornadoes can damage or destroy vegetation an man made structures and can kill or injure people and animals.
Are tornadoes visible?
Yes. Tornadoes are often made visble by condensation in their funnels and by dust and debris. However, some tornadoes may be obsured from view by rain or the dark of night.
What are the tornadoes made of?
Tornadoes are just rapidly moving columns of air. The reason that they are black is because that is the color of the dirt that they pick up.
