A tornado that does not touch the ground is a funnel cloud.
funnel cloud it is not really a tornado . :)
Yes
Not always. The funnel is only the portion of the tornado that is visible. The winds of a tornado at ground level may still be capable of causing significant damage even if the visible funnel does not reach ground level. When this occurs it is usually evidenced by swirling dust or debris beneath the funnel. That is usually enough to report a tornado. Oftentimes, though, the funnel does touch the ground in which case there is definitely a tornado. Also of note is that sometimes you have a funnel that does not produce damaging winds on the ground. These are not counted in tornado statistics.
Yes. The funnel of a tornado does not have to reach the ground for the circulation to touch down. If there is swirling debris on the ground beneath a funnel cloud then the tornado has touched down and, if it is more than just dirt being lifted, is probably doing damage.
No. A tornado starts in the clouds and extends towards the ground. Until it reaches the ground it is not a tornado but a funnel cloud.
No. Tornadoes descend from the base of thunderstorms, usually associated with very tall thunderstorms. The tornado begins in the lower portions of the storm. Furthermore, if the vortex does not touch the ground, it is not considered a tornado.
It depends what you call a tornado. Most tornado-like clouds do not touch the earth's surface. Some say that until it touches the ground it is not a tornado but a funnel cloud; however the definition of a tornado does not state that it must touch the ground. It all depends on what you're taught.
Yes
Most of them touch down on ground.
tornado
Air near the ground spirals inward and upward in and near the tornado.
By the meteorological definition a tornado extends from cloud base to the ground. If it does not, it cannot produce damage. However, just because the visible funnel doesn't touch the ground doesn't mean the strong winds don't. It is the vortex of wind which defines a tornado, not the funnel.
A tornado has actually touched down on the ground - a funnel cloud is a spinning cloud that has not actually touched the ground.
A tornado that doesn't touch the ground isn't a tornado; it is a funnel cloud. However if the funnel is pulling debris off the ground or making some other type of contact with the ground it is a tornado.
Yes. In order to be considered a tornado the vortex, though not necessarily the visible funnel, mus touch the ground.
Yes. Debris was lifted into the air meaning the circulation reached the ground, though it appears to have been very weak. If it doesn't touch down it isn't counted as a tornado.

There were several tornadoes in Florida in March of 2011, They did indeed touch the ground; they wouldn't have been tornadoes otherwise.
