Can a tornado cause damage without touching the ground?
Yes and no. The funnel of a tornado does not have to reach the ground for damaging winds to occur at ground level. However, if those winds reach the ground then the tornado has touched down even if the funnel hasn't.
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…
By definition a tornado must be in contact with both the ground and the cloud base. So, in that sense, yeas. But this only means that the violent circulation must make this connection, not necessarily the visible funnel. Additionally, sometimes a tornado starts to form, but dissipates before touching down, but in that case it is not considered a tornado.
A sandstorm is a kind of windstorm with straight-line winds that creates a cloud of sand and dust that has been picked up from the ground. A tornado is a violently rotating column of air extending from the base of a thunderstorm to the ground with damaging, circular winds. A tornado usually flows a narrow damage path.
Tornado damage is caused by wind and debris, with the first visible damage usually occurring to the roof, windows, and exterior walls. Earthquake damage is caused by shaking and distortion of the ground. Structures destroyed by earthquakes usually collapses where they stand while those destroyed by tornadoes are often at least partially blown away.
It is classified as a tornado when the circulation, which originates within a thunderstorm, is confirmed to have made contact with the ground. Usually this is confirmed through damage done by the tornado, but video or eyewitness testimony from a trained spotter can be used as well for tornadoes that cause little to no damage. In some cases it can take extensive analysis to determine if any event was a tornado or strong thunderstorm winds…
Not exactly. If a tornado is imminent then Doppler radar will probably detect the rotation wand a warning will be issued that a tornado may soon form. Often, especially with areas of major damage, the tornado has already been on the ground for at least a few minutes and moves into the area. Meteorologists can often detect the signature of a tornado on radar will announce where the tornado is and where it is going.
obviously depending on the size of the tornado it may not do a great deal of damage, just rustle up the trees and bushes but that's about it. But if your talking about a powerfull tornado like an F4 or F5, and its got enough energy to stay on the ground then it can literally wipe out a whole area which will destroy the habitats and most likely the inhabitants of those habitats.
