The rotation in a thunderstorm that produces a tornado comes from wind shear, a difference in wind speed and direction with altitude. In the systems that produce tornadoes in the northern hemisphere, you will typically find lower level winds coming out of the west with winds higher up coming out of the south. A counterclockwise change in direction. This creates a counterclockwise circulation in the thunderstorm that can produce a tornado. In the Southern Hemisphere the upper level winds are out of the north and clockwise rotation results.

What causes cloud formation?
When water evaporates into vapor it makes clouds...
Because of their shape when seen from the ground tornadoes are sometimes called?
Funnel clouds
What kind of weathering is a sign of tornadoes?
Signs of a potential tornado include rotation in the clouds, a persistent lowering of the cloud base, and a hole opening up in the clouds near the back of a storm (these are all potential precursors). Other signs include a funnel or con shaped extension of the cloud base, and swirling debris on the ground, indicating that a tornado or funnel cloud has formed.
what is a good sentence for funnel cloud?
The funnel cloud turned into a tornado.
A funnel cloud touching the ground is what?
a funnel cloud touching the ground is then called a tornado
What is a funnel cloud that touches the cloud?
All funnel clouds touch the clouds. A funnel cloud that touched the ground is called a tornado.
Which type of storm has a funnel cloud?
Tornadoes typically have funnel clouds.
Is a cirrus cloud a funnel cloud?
No. A cirrus cloud is a high, wavy, thin cloud formed of ice crystals. Funnel clouds are usually formed from cumulonimbus clouds (thunderclouds) at lower altitudes.
What severe weather in associated with a funnel cloud?
Funnel clouds are associated with tornadoes.
Are tornadoes formed by storm clouds or funnel clouds?
A tornado is formed from storm clouds. The funnel cloud is the tornado before it touches down.
A vast tropical funnel cloud in the pacific ocean?
A large, rotating tropical storm in the Pacific Ocean would be a typhoon, but typhoons to not have funnel clouds. A funnel cloud anywhere is simply a funnel cloud.
What causes a funnel cloud?
Afunnel cloud is a funnel-shaped cloud of condensed water droplets, associated with a rotating column of wind and extending from the base of a cloud (usually a cumulonimbus or towering cumulus cloud) but not reaching the ground or a water surface. A funnel cloud is usually visible as a cone-shaped or needle like protuberance from the main cloud base. Funnel clouds form most frequently in association with supercell thunderstorms.If a funnel cloud touches the ground it becomes a tornado. Most tornadoes begin as funnel clouds, but many funnel clouds do not make ground contact and so do not become tornadoes. Also, a tornado does not necessarily need to have an associated condensation funnel---if strong cyclonic winds are occurring at the surface (and connected to a cloud base, regardless of condensation), then the feature is a tornado. Some tornadoes may appear only as a debris swirl, with no obvious funnel cloud extending below the rotating cloud base.A funnel cloud that touches down on, or moves over water is a waterspout.
How do you identify a funnel cloud?
A funnel cloud is a funnel, cone, or trunk shaped cloud that extends downward from the cloud base and rotates. If dust or debris can be seen swirling beneath it, that means a tornado is con the ground. Below are pictures of some funnel clouds.
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.
What is synonym for funnel cloud?
A synonym for funnel cloud is condensation funnel. Tornado may also be considered a synonym, though this is a bit loose as not all funnel clouds become tornadoes, and some tornadoes do not have a visible funnel.
Funnel shape storm cloud formations are called?
tornado clouds
Is a stratus cloud a funnel cloud?
No. Stratus clouds are low level, usually flat clouds that can bring rain or snow but usually do not indicate hazardous weather. A funnel cloud is a rotating downward projection of a cumulonimbus that is often cone shaped.
