Signs of tornadic activity usually start with a wall cloud, which is attached to the base of a cumulonimbus cloud.
The cloud that forms the visible part of a tornado is called a funnel cloud.
Cumulonimbus clouds can spawn a tornado.
A wall cloud, or, if a potential tornado is already developing, a funnel cloud.
Before it reaches the ground, the precursor to a tornado is called a funnel cloud.
A storm does not become a tornado; it produces one. The rest of the storm remains largely unchanged as a cumulonimbus cloud. The tornado itself forms a funnel cloud.
To a degree. A tornado is often made visible by a cloud known as a condensation funnel or funnel cloud. The tornado itself is not a cloud, however, but a violent rotating windstorm. The condensation funnel is sometimes absent in a tornado.
When a tornado forms it often produces a funnel cloud.
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, 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.
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.
Not exactly. A tornado itself is a violently rotating windstorm that usually creates a condensation funnel, but a tornado can develop without a funnel.
