What column of violently rotating air in the shape of a funnel that extends from the bottom of a cumulonimbus cloud to the ground?
This is called 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.
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.

This is called a tornado.
Where is the wash arm located on the dishwasher?
There are usually 2 rotating wash arms, top and bottom.
How does one obtain a cool flame with the laboratory burner?
Adjust the rotating air-inlet sleeve at the bottom on the spout.
Direction is the solar system rotating and revolving?
If you looked from the "top" it would be clockwise, but then if you looked from the bottom it would be counter-clockwise (anti-clockwise). Since there is no "top" or "bottom", there is no direction except "around".
How do tornadoes work?
That is not fully understood and is the topic of ongoing research by scientists. What is known is that tornadoes are violently rotating vorticies of air that form during some thunderstorms. Wind air in and near a tornado spiral inward and upward at very high speeds around a center of intense low pressure. Most tornadoes form from the mesocyclone, or rotating updraft, of a powerful type of thunderstorm called a supercell. The bottom portion of the mesocyclone tightens and intensifies to produce the tornado, but it is not known how this happens or why happens in some storms and not others.
Does batman arkham asylum have an auto-save feature?
Yes it does, after zoning through to another area, in the bottom righthand side of your screen you'll see a rotating circle when it is autosaving.
How do you spin a plate on a stick?

How can you unlock portrait orientation in iphone5?
Swipe up from the bottom of the screen to open the Control Centre. The fifth circle is called Orientation Lock. When it is on it keeps the screen from rotating, when it is off the screen rotates.
How is hydroelectric energy converted to electricity?
in an hydrolectric plant there are turbines in the bottom then the water is made to fall from a great height which causes the turbine to rotate and producing electricity in same way as done in rotating dynamo
How do you change which mii you play as on Mario kart 7?
You have to start the game and get to the main menu. Click on "Mario Kart Channel" and when you see the rotating Earth, look in the bottom right corner of the bottom screen where it says "settings". Click it, and it should have an option of changing your Mii. Find the one you want and Viola!!
What contains the various strength magnifying lenses of a light microscope?
The objective lenses are typically mounted in a rotating mount called a "nosepiece" which is located at the bottom of the ocular tube, just above the "stage" that holds the viewed slides.
What valves do you leave open when cleaning pool?
You should have two valves: one for the skimmers and another for the bottom drain. Close the valve to the bottom drain. One of your skimmers should have a rotating disc which will cover the intake at the bottom of the skimmer intake hole. Rotate the disc. In this manner all the suction from the pool pump will be at the one remaining skimmer. Attach your cleaning hose to this remaining skimmer while vacuuming the pool.
