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 kind of storms are classified on the Fujita Scale?
Tornadoes.
What towns do tornadoes come from?
tornadoes do not come from towns, the come from a kind of thunderstorm called a supercell. A tornado can strike virtually anywhere that gets severe thunderstorms.
Where do tornadoes not occur and why?
Tornadoes do not occur in polar regions, because the cold air does not provide enough energy. They do not occur in extreme desert regions because there is not enough moisture to fuel the right kind of thunderstorm.
What kind of fronts are involved in tornadoes?
Tornadoes are not a direct product of fronts but rather of thunderstorms. The storms that produce tornadoes most commonly occur along a cold front or dry line, but can be associated with stationary fronts or, less often, warm fronts. Some tornadic storms develop in the absence of any fronts.
Are tornadoes calm?
No. Tornadoes are violent.

What kind of wheater is on Mercury?
Mercury doesn't have any kind of weather except the fact that Mercury is to hot facing the Sun and to cold on the dark side
How do mountaintops weather faster than rocks at sea level?
Mountaintops wheater faster bucause if they are tall ice,rain,and wind can wheater it and if it's a small mountaintop gravity can wheater it.
How old is David Wheater?
David Wheater is 24 years old (birthdate: February 14, 1987).
What kind of storm is normally associated with tornadoes?
Supercells are normally associated with tornadoes.
What kind of weather brings tornadoes?
Tornadoes are produced by very strong thunderstorms.
What kind of thunderstorm produces tornadoes?
super cell thunder storms produce most, not all, tornadoes. mostly the violent kind.
