Does the air form a vortex in a tornado?

Answer 1

Fist you need air that is warm and moist. Air like this is often unstable, which allows it to produce thunderstorms. Then you need something to trigger these storms. Usually it is a mass of cooler or direr air colliding with the original air mass, though sometimes the storms may be triggered by a hurricane or other storms system moving in. You also need wind shear. This is ultimately what gives the storms the rotation they need to produce tornadoes.

Answer 2

General conditions for tornado formation occur when wind shear, which can produce horizontal vorticity, interacts with thunderstorms.

The horizontal vorticity is turned vertical by a thunderstorm and sets the storm rotating, turning it into a supercell. The strong rotating updraft of the storm is called a mesocyclone. If the storm intensifies rapidly enough a downdraft may warp around the bottom portion of the mesocyclone, tightening and intensifying the rotation and bringing it in contact with the ground to form a tornado.

Answer 3

Tornadoes usually form in what meteorologists call tornado alley which are states like Texas, Oklahoma, Kansas, etc. Tornadoes can form mostly any time of day and the most dangerous are at night because it's so dark and you could possibly not see them. Usually tornadoes form with the warm air from the gulf coast and the cold air from Canada and when you get those two clashing together, that usually makes thunderstorms and sometimes tornadoes (especially in the Midwest states)

Answer 4

Tornadoes are typically associate with thunderstorms called supercells. Such storms can produce strong winds, heavy rains, and large hail. The conditions that lead to these storms can vary, they usually form when a warm moist air mass collides with a cooler drier one. In order to be come supercells, though, these storms must encounter wind shear, which is a condition in which the speed and direction of wind changes with altitude.

Answer 5

For tornadoes:

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.

For hurricanes:

A disorganized cluster of thunderstorm with low pressure moves or forms over warm ocean water. The air must be warm and moist and there should be little or no wind shear. The moisture from the ocean causes the storms to strengthen and organize. At the same time air flowing into the low pressure area begins to rotate as a result of earth's spin. When the system develops a closed, organized circulation it becomes a tropical depression, the lowest category of tropical cyclone. As the storm strengthens further the pressure drops and wind speed increases. When sustained winds reach 39 mph (63 km/h) the system becomes a tropical storm. When they reach 74 mph (119 km/h) the storm becomes a hurricane.

Answer 6

Tornadoes generally form when strong thunderstorms encounter horizontal vorticity from wind shear. This give them the rotation needed to produce tornadoes.

Answer 7

Tornadoes need strong thunderstorms and wind shear to form.

Answer 8

all around the world except Antarctica

Answer 9

Yes. A tornado is a vortex.
