How do cumulus clouds form tornadoes?
Cumulus clouds can develop into cumulonimbus clouds, which are usually thunderstorms. All thunderstorms contain an updraft, which is a rising air current. Under the right conditions this updraft can start rotating, becoming a mesocyclone. The thunderstorm is now called a supercell. Sometimes the bottom of the mesocyclone can tighten and intensify to produce a tornado.
What is a tornado and how do they form?
A tornado is a violently rotating and destructive column of air extending from the base of a thunderstorm to the ground.The formation of tornadoes these 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.
Do tornadoes form from fast moving air?
In a way, yes. Tornadoes form from a larger, preexisting rotating updraft called a mesocyclone. It is believed that strong winds from a special downdraft wrap around the bottom of the mesocyclone, causing it to tighten and intensify to produce a tornado. Generally, the stronger the mesocyclone, the stronger the tornado.
What is a tornado and how is it created?
A tornado is a violently rotating windstorm that connects tot he base of a thunderstorm to the ground, often made visible by a condensation funnel. To form a tornado, 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.
What has a funnel and is at the bottom of a cumulonimbus cloud?
A tornado has a funnel and is at the bottom of a cumulonimbus cloud. If its winds do not reach the ground, though it is just a funnel cloud.

What happens when the spinning of air moves to the bottom of the cumulonimbus cloud?
It forms a funnel cloud.
The trachea extends from the bottom end of the?
larynx
Why do cumulonimbus clouds dissipated at the bottom first?
because the bottom loses its energy first, acoording to formation to full energy to dissipating stage
What extends from the top of the troposphere to the bottom of the mesophere?
The stratosphere.
The extends from the top of the troposphere to the bottom of the mesosphere?
Stratosphere
The coccygeus extends from the coccyx and sacrum to the?
bottom two bones of spine
What type of cloud would have mostly severe weather?
cumulonimbus clouds. They are puffy that appear to rise up from a flat bottom.
How do you compress the rear caliper on a 2001 infiniti i30?
The rear caliper compresses into the bore by rotating the face clockwise. You can do this with a special tool or with long, needle nose pliers. Unlike the front calipers, the piston extends and retracts on a spiral screw attached to the bottom of the caliper bore.

Under the right conditions this updraft can start rotating, becoming a mesocyclone. The thunderstorm is now called a supercell. Sometimes the bottom of the mesocyclone can tighten and intensify to produce a tornado.
What storm forms when funnel clouds poke through the bottom of a cumulonimbus cloud and makes contact with the ground?
Such a storm is called a tornado.
