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 start at the top?
Tornadoes start up in the clouds & make their way down to touch land.
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.
Do tornadoes start at the bottom?
No, Tornadoes start inside the clouds of their parent thunderstorms and descend towards the ground. Somtimes they can appear to form up from the ground because the vortex is just swirling air when it reaches thr ground and therefore cannot be seen until it starts picking up dust from the ground.
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 the bottom of a whirlpool called?
The bottom of a whirlpool is called the vortex. It is the central region where water spirals downward into a rotating mass.
Where is the wash arm located on the dishwasher?
There are usually 2 rotating wash arms, top and bottom.
What is the bottom of tornado called?
There is no particular term for the bottom of a tornado. The base of a tornado may be shrouded in a debris cloud.
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".
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?
Here is how you do it.Put a stick under a plastic plate's rim.Start rotating the stick, holding the bottom still.When the plate is spinning fast, hold the stick still.
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!!
If the axis of rotation is near the top of the container will the denser particles tend to move to the top or bottom of the container?
Denser particles in a rotating container will tend to move towards the bottom, away from the axis of rotation due to centrifugal force. This is because denser particles have more inertia and are less affected by the rotation.
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.
