No. In fact most of the time one won't form.
If you're concerned about tornadoes what you should be on the lookout for is rotation.
No, it can not happen. You will always need a cloud to form a tornado. The kind of cloud that a tornado uses is a cumulonimbus cloud.
The condensation funnel of a tornado is basically a cloud formed when moisture inside a tornado condenses and in that sense it is similar to an ordinary cloud. The debris cloud of a tornado is a cloud of debris picked up by a tornado usually from buildings and trees the tornado has damaged or destroyed.
A tornado that does not touch the ground is a funnel cloud.
The wall cloud is a large section of cloud extending down from the base of a thunderstorm. The wall cloud marke the strongest part of the mesocyclone, which is the rotating updraft that can produce a tornado. A funnel cloud or tornado usually extends from the base of a wall cloud.
Yes. A tornado is often visible as a funnel cloud as it develops.
No, it can not happen. You will always need a cloud to form a tornado. The kind of cloud that a tornado uses is a cumulonimbus cloud.
No. A tornado is a violently rotating column of air extending from the base of a thunderstorm to the ground. A tornado is often, but not always made visible by a funnel cloud. But the tornado is not the cloud itself.
A wall cloud will form and the cloud might build up a funnel!
Sometimes, but not always. In a typical situation you will see a low-hanging cloud beneath a thunderstorm called a wall cloud. As the circulation of the tornado develops, a smaller rotating cloud called a funnel cloud will develop in the wall cloud and extend toward the ground. If the funnel cloud reaches the ground or if there is a whirl of dust beneath the funnel cloud, then the tornado has touched down. This is the classic depiction, however, it does not always happen this way. In many cases, the area where the tornado is forming is obscured by rain. If the air beneath a thunderstorm is dry, the the tornado may develop without a visible funnel. Finally, many tornadoes occur at night, when it is too dark to see them.
Either the funnel cloud or the violent, rotating winds associated with it must reach the ground in order to be classified as a tornado.
Nothing special. All tornadoes stretch from cloud base to the ground. If the vortex doesn't reach cloud base or the ground it isn't a tornado.
According to the glossary of meteorology a tornado is defined as "a violently rotating column of air, pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud." In meteorological terms the vortex described above must connect to both the ground and the cloud base to be considered a tornado.
The condensation funnel of a tornado is basically a cloud formed when moisture inside a tornado condenses and in that sense it is similar to an ordinary cloud. The debris cloud of a tornado is a cloud of debris picked up by a tornado usually from buildings and trees the tornado has damaged or destroyed.
The cloud that forms the visible part of a tornado is called a funnel cloud.
No, the wall cloud is a lowered section of the cloud base from which a tornado or funnel cloud descends. The dark cloud at the base of a tornado is called the debris cloud.
A tornado that does not touch the ground is a funnel cloud.
A tornado usually emerges from a wall cloud, which is at the base of a cumulonimbus cloud.
