Cumulonimbus
The cloud formation before a tornado funnel forms is typically a rotating wall cloud. This type of cloud is often associated with severe thunderstorms and can indicate that a tornado may develop. It is important to take shelter if you see a rotating wall cloud, as it could produce a tornado.
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.
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.
Supercell thunderstorms are the type of clouds associated with tornado formation. These types of storms have a rotating updraft, which can lead to the development of tornadoes under the right atmospheric conditions.
The low hanging cloud base that spawns tornadoes is called a wall cloud. Wall clouds are often associated with severe thunderstorms and can be a precursor to tornado formation.
There often is. Most tornadoes are associated with a wall cloud but not all.
Wall cloud.
To be classified as a tornado, a funnel cloud must make contact with the ground. Once the funnel cloud touches the ground, it becomes a tornado and is classified based on its size, intensity, and associated damage.
A tornado is typically spawned from a supercell thunderstorm cloud, known as a mesocyclone. These types of clouds are characterized by a rotating updraft, which can produce the necessary conditions for tornado formation.

The wall cloud itself doesn't do the damage. The wall cloud is an indicator of rotation in a thunderstorm that can lead to the formation of a tornado.
No, some tornadoes will form without a wall cloud. In most cases there are of a variety called landspouts, which are tornadoes that do not form in association with the mesocyclone of a supercell. These tornadoes are typically weak, though on occasion have been known to cause damage as high as F3.
