Best Answer

It varies, but it will always occur during a thunderstorm. If that area of the storm is not obscured by rain or the dark of night you will usually see a rotating block of clouds lowered from the main cloud base called a wall cloud. Near this a downdraft will blast a hole in the clouds. Not long afterwards there will likely be strong winds. Then the funnel begins to lower from the wall cloud and a swirl of dust or debris may appear on the ground below it as the tornado connects to the ground.

No. Tornadoes form from thunderstorms. By definition a tornado must make contact with both the ground and the cloud base. However, small whirlwinds, such as dust devils, can form on cloudless days. These look somewhat like tornadoes, but are nowhere near as strong.


Is there any kind of tornado made from water?

No. A tornado is defined as a violently rotating column of air. A tornado can form on a body of water, in which case it is called a waterspout. Some water can get pulled up into it, but it is still primarily a vortex of air. Whirlpools, vortices that form in water, can look like tornadoes, but are not the same thing.
