The process of tornado formation usually starts about three miles above the ground, within a thunderstorm. A larger, less intense circulation, called a mesocyclone, tightens and stretches, extending toward the ground. The funnel itself is a result of moist air being drawn into the vortex. The low pressure inside the vortex causes temperature to drop, which in turn causes condensation.

Where does a tornado descend from?

A tornado descends from the base of a thunderstorm.


Is the dark base of a tornado called the wall 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.


What does a tornado come out of?

A tornado usually emerges from a wall cloud, which is at the base of a cumulonimbus cloud.


What is the wall cloud in a tornado?

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.


Is a tornado a 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.


What types of clouds are associated with tornadoes?

Tornadoes are produced by thunderstorms, which take the form of cumulonimbus clouds. Most tornadoes descend from a wall cloud at the base of the parent thunderstorm. The developing vortex of a tornado is often visible as a funnel cloud.


What could happen in a tornado if it touches the cumulonimbus cloud?

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.


Name of lower cloud base often associated with tornado formations?

Wall cloud.


Does a tornado come from a cumulonibus cloud?

Yes. Tornadoes are produced by thunderstorms, which from from cumulonimbus cloud. Usually a wall cloud and then a funnel cloud develop at the base of a cumulonimbus cloud before a tornado touches down.


What is the bottom of tornado called?

There is no particular term for the bottom of a tornado. The base of a tornado may be shrouded in a debris cloud.


What are tornado cloud shapes called?

I think The cloud that forms in the tornado itself is a funnel cloud. The funnel cloud often descends from a wall cloud, which in turn is connected to the base of a cumulonimbus clouds and the best sleep money CAN buy cutt.ly/hkZXIOo


What happens to the sky when a tornado hits?

Tornadoes occur during severe thunderstorms, typically supercells. So you will typically see thick, often very dark storm clouds. The clouds may take on unusual colors, such as green, yellow, or turquoise. The cloud base itself may appear ragged, and there will usually be a rotating lowering of the cloud base called a wall cloud. The tornado will descend from the wall cloud. See the links for examples of wall clouds.


How does the anatomy of a cumulonimbus cloud help allow the formation of a tornado?

It's not so much the anatomy of the cloud itself, but that of the wind currents in and around it. First, the updraft of the storm must rotate, this rotation often producess a lowering of the cloud base called a wall cloud. Second, a downdraft must descend from the back of the storm, often producing a hole in the clouds. This downdraft allows the rotating updraft to produce a tornado.


How tall can the funnel of a tornado get?

The funnel of a tornado always connects to cloud base and typically all the way to the ground (the circulation of a tornado can reach the ground even if the funnel does not). Cloud base height is variable but in a tornado supercell is usually about 3000 feet to a mile above the ground. The circulation of the tornado usually goes a great distance above cloud base and can reach heights of more than 4 miles.


Is a funnel shaped tornado a mesocyclone?

No, the mesocyclone is the larger circulation that the tornado forms from. It can sometimes be seen as a lowering of the cloud base called a wall cloud.


How do you understand the direction in which the tornado will move depending on the angle it forms with the base cloud?

It is not uncommon for the base of a tornado to lag a bit behind where it connects to the cloud base so that it appears to lean forward. See the link below for a video. This effect is very pronounced in this tornado in Mississippi.


What does tornado mean?

A tornado is a violent, rotating column of air which is in contact with both the surface of the earth and a cumulonimbus cloud, in rare cases, the base of a cumulus cloud.


What cloud type does a tornado start with?

Signs of tornadic activity usually start with a wall cloud, which is attached to the base of a cumulonimbus cloud.


What is the rotation of a tornado?

The rotation of a tornado is it spinning or turning. A tornado is defined as a violently rotating column of air in contact with the cloud base and the ground.


What clouds are there in a tornado?

The funnel of a tornado itself is a called a funnel cloud, though this term is usually reserved for when it does not touch the ground. The funnel cloud often emerges from a low-hanging cloud called a wall cloud, which is attatched to the base of a cumulonimbus cloud.


Can you tell if there's a tornado?

Usually. If you see rotation in the clouds it means a tornado may form. If you see a cone, cyclinder, or "elephant trunk" shaped cloud extending from cloud base a tornado may already be on the ground.


What is a tornado definicion?

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.


Can A Tornado Happen With No Clouds?

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.


What is a wall cloud on a tornado?

A wall cloud is a lowering of a cloud base that is often seen before a tornado forms. It marks the most intense portion of the mesocyclone, the rotating updraft from which a tornado forms. The links below shows picture of what wall clouds often look like.


What are condensation funnel cloud and debris 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.
