funnel cloud?

Answer 1

A condensation funnel extending from the base of a towering cumulus or Cb, associated with a rotating column of air that is not in contact with the ground (and hence different from a tornado). A condensation funnel is a tornado, not a funnel cloud, if either a) it is in contact with the ground or b) a debris cloud or dust whirl is visible beneath it.

Answer 2

A funnel cloud is usually found at the leading edge of a storm, and is called a funnel because it begins taking the shape of an inverted cone. If a funnel cloud reaches the ground, it is called a "tornado", a "whirlwind", or a "twister." It is formed by being near the apex of a low pressure area, much like the spot in the bathtub just over the drain. When you let the water out, the low pressure causes the water to create a little vortex. You'll see the vortex form, and dis-form, until at some stable point its tail goes all the way into the drain. A funnel cloud is like that. A tornado is created when the "funnel" touches the earth--and is signalled normally by flying debris.
Some funnel clouds never touch the ground, but clearly are spinning clouds.
A dust-devil, on the other hand, is the same phenomena, just not created by a cloud, but rather by a low-pressure spot within swirling dust

Answer 3

A funnel cloud is a tornado that is still airborn. The instant is touches the surface, it is called a tornado or water spout.

Answer 4

A funnel cloud is a rotating column of air that doesn't touch the ground. When it does touch ground, it is called a tornado.
