Cumuliform

Cumuliform Anvil - A thunderstorm anvil with visual characteristics resembling cumulus-type clouds (rather than the more typical fibrous appearance associated with cirrus).

Cumuliform Cloud cloud that forms by convection. Typically a heap cloud such as cumulus. Cumulonimbus ...

Cumuliform: having the appearance or character of cumulus clouds. Cumulonimbus: a cloud of a class indicative of thunderstorm conditions characterized by large, dense towers that often reach altitudes of 30,000 ft (9000 m) or more, ...

cumuliform—A term descriptive of all convective clouds exhibiting vertical development in contrast to the horizontally extended stratiform types.

CUMULIFORM Clouds composed of water droplets that exhibit vertical development. The density of the droplets often blocks sunlight, casting shadows on the earth's surface. With increasing vertical height, they are often associated with convection.

Hard, cumuliform anvil overhang, a vertical Cb edge, and flanking line are all visible in this southeastward view of a supercell storm. Mammatus can be seen on the underside of the north Texas supercell.

C3250 Cumuliform cloud Cloud with the bulging appearance of a Cumulus. When such clouds, arranged in lines and joined by a common base, possess protuberances giving them a turreted appearance, they are classed in the species castellanus.

Convection cloud Cumuliform cloud which forms in the atmosphere as a result of convection. Such clouds are also called clouds of vertical development.

It most often falls from stratiform clouds, but can fall as snow showers from cumuliform ones. It usually appears clustered into snowflakes. It is reported as "SN" in an observation and on the METAR.

Shower Precipitation from a cumuliform cloud. Characterized by the suddenness of beginning and ending, by the rapid change in intensity, and usually by a rapid change in the condition of the sky.

CumuliformDescriptive of all clouds with vertical development in the form of rising mounds, domes, or towers ...

convective condensation level (CCL) The level above the surface marking the base of a cumuliform cloud that is forming due to surface heating and rising thermals.

A violently rotating column of air, in contact with the ground, either pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud.

Landspouts form during the growth stage of convective clouds by the ingestion and tightening of boundary layer vorticity by the cumuliform tower's updraft.

Meteorologists however distinguish between precipitation (rain, snow, hail etc.) falling from cumuliform cloud in an unstable environment - a shower, from that falling from layer clouds in a generally stable environment which are just called rain, ...

Convection may be dry, that is, with relative humidities less than 100%, especially in the boundary layer, but is commonly moist, with visible cumuliform clouds.

A term used to signify clouds with bases below 6,000 feet and are of a stratiform or a cumuliform variety. Stratiform clouds include stratus and stratocumulus. Cumuliform clouds include cumulus and cumulonimbus.

Altocumulus- Mid-altitude clouds with a cumuliform shape. Altostratus- Mid-altitude clouds with a flat sheet-like shape. Anabatic- wind flowing up an incline, such as up a hillside; upslope wind.

Eye Wall/Wall Cloud An organized band of cumuliform clouds immediately surrounding the center of a tropical cyclone. Eye wall and wall cloud are used synonymously.

Comma Cloud Band of organized cumuliform clouds that look like a comma from a satellite's perspective. Comma clouds are indicators of heavy storms.

cloud forms stratiform: flat or layered cumuliform: puffy or globular cirroform: wispy, made of ice crystals ...

Stratiform Descriptive of clouds of extensive horizontal development, as contrasted to the more narrow and vertically developed cumuliform type. Stratiform clouds cover large areas but show relatively little vertical development.

Intermittent precipitation from a cumuliform cloud, usually of short duration but often heavy. Sinks(4) ...

Anvil The spreading of the upper portion of a cumulonimbus cloud into an anvil-shaped plume usually of fibrous or smooth appearance. Strong or severe thunderstorms often have thicker anvils with the side and bottom having a cumuliform or slowly ...

Anvil Rollover - [Slang], a circular or semicircular lip of clouds along the underside of the upwind part of a back-sheared anvil, indicating rapid expansion of the anvil. See cumuliform anvil, knuckles, mushroom.

crystals or the mixture of both with its base above the surface of the Earth. It can be classified according to the height of its base (low, middle or high) or to the type of development, which can be horizontal (stratiform) or vertical (cumuliform).

They usually appear on the upwind side of a back-sheared anvil, and indicate rapid expansion of the anvil due to the presence of a very strong updraft. They are not mammatus clouds. See also cumuliform anvil, anvil rollover.
