A rotating, visible extension of cloud, with the top attached to the cloud but not touching the ground.

Simply,a rotating conelike cloud that extends downward from the base of a thunderstorm. When it reaches the surface it is called a tornado. It is a cloud extending from the base of a towering cumulus or Cb, associated with a rotating column of air that is not in contact with the ground (and hence different from a tornado). A condensation funnel is a tornado, not a funnel cloud, if either a) it is in contact with the ground or b) a debris cloud or dust whirl is visible beneath it.

A funnel shaped cloud that extends from a cumulus or cumulonimbus cloud; this cloud is related to a rotating column of air that is not in contact with the ground. -- Gradient (pressure gradient) Change of value of the atmospheric pressure per unit of distance. The greater the change per unit of distance, the stronger the gradient, and the stronger the winds. -- Heavy Snow High Wind The sustained wind of forty mph or greater and/or gust greater than fifty-eight mph.

an incipient tornado that has not reached the ground

a rotating area of cloudiness which generally extends from the base of a large thunderstorm cloud

a " Tornado " aloft before it touches the ground

a tornado that has not touched the ground or water

A funnel-shaped cloud extending from a towering cumulus or cumulonimbus base. It is associated with a towering air column that is not in contact with the ground. If a ground-based debris or dust whirl is visible below the funnel aloft, the cloud is a tornado.

cone-shaped spinning column of air that hangs well below the base of a thunderstorm cloud

A funnel-shaped cloud extending from a towering cumulus or cumulonimbus base. It is associated with a rotating air column that is not in contact with the ground. The cloud is a tornado if a ground-based debris or dust whirl is visible below the funnel aloft.

A rotating cone like cloud that extends downward from the base of a thunderstorm. It DOES NOT touch the ground. When it reaches the surface it is called a "tornado".

A column of air that rotates violently and extends from the base of a cumulus cloud.

A tornado whose circulation has not reached the ground. Often appears as a rotating cone like cloud that extends downward from the base of a thunderstorm.

A rapidly rotating column of air extending from a cumulonimbus cloud with a circulation that does not reach the ground. once a funnel cloud reaches the ground it is then called a tornado.

A rotating column of air extending from a cloud but not reaching the ground.

A rotating column of air forming a pendant from a thunderstorm with the circulation not reaching the ground.

A rotating, cone-shaped column of air extending downward from the base of a thunderstorm, but not in contact with the ground. When it reaches the ground it is then called a tornado.

A rotating, visible extension of cloud, pendant to a cumulus or cumulonimbus with circulation not reaching the ground.

A funnel-shaped cloud that does not touch the ground

A funnel extending from the base of a towering cumulus or cumulonimbus cloud, associated with a rotating column of air that is NOT in contact with the ground. The terms funnel cloud and tornado are NOT interchangeable.

A violently rotating column of air extending downward from the base of a thunderstorm cloud. If and when it touches the ground, it becomes a tornado.

A rotating column of air, extending from a towering cumulus or cumulonimbus cloud, that is not in contact with the ground.

This situation is the characteristic image of tornados as the densely swirling mass of wind shaped like a funnel. The situation arises because the wind system has generated a strong enough wind velocity.

Cloud formed at the core of a waterspout or tornado vortex, sometimes extended right down to the ground, caused by the reduction of pressure at the center of the vortex.

Violently rotating column of air that is not in contact with the ground. A tornado passes through the funnel cloud stage during its development and dissipation.

A tornado cloud or vortex cloud extending downward from the parent cloud but not reaching the ground.

condensation cloud, typically funnel-shaped and extending outward from a cumuliform cloud, associated with a rotating column of air (a vortex) that may or may not be in contact with the ground. If the rotation is violent and in contact with the ground, the vortex is a tornado. Funnel clouds can occur through a variety of processes in association with convection. For example, small funnel clouds are infrequently seen extending from small, dissipating cumulus clouds in environments with significant vertical wind shear in the cloud-bearing layer. Bluestein, H., 1994: High-based funnel clouds in the Southern Plains. Mon. Wea. Rev., 122, 2631–2638.

A violent, rotating column of air visibly extending from the base of a towering cumulus or cumulonimbus toward the ground, but not in contact with it. It is reported as "FC" in an observation and on the METAR.

For the album of the same title by Hem, see Funnel Cloud (album).

Funnel Cloud is the fourth album by folk rock band Hem. It is slated to be released on Nettwerk on September 5, 2006. Considered the band's most ambitious work to date, they recorded the album accompanied by a 21-piece orchestra, as well as James Iha of the Smashing Pumpkins.
