It is usually just called a debris cloud or dust whirl.
This is called a tornado.
A tornado that does not touch the ground is a funnel cloud.
Not technically. It is the beginning of a tornado, but they are categorized differently. It is not considered a tornado until it reaches the ground with damaging winds.
The cloud of condensation the a tornado produces is funnel-shaped, wider at the top than at the bottom.
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.
This is referred to as the debris cloud.
A wall cloud, or, if a potential tornado is already developing, a funnel cloud.
A tornado has a funnel and is at the bottom of a cumulonimbus cloud. If its winds do not reach the ground, though it is just a funnel cloud.
There is no particular term for the bottom of a tornado. The base of a tornado may be shrouded in a debris cloud.
This is the birth of a tornado.
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.
This is called a tornado.
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.
The funnel of a tornado is caused by air decompressing and cooling as it enters the tornado, causing moisture to condense and form a cloud. As the air moves up it cools further, resulting in more condensation. This results in a cloud that is wider at the top than at the bottom.
Not technically. It is the beginning of a tornado, but they are categorized differently. It is not considered a tornado until it reaches the ground with damaging winds.
