Cumulus (Cb) A principal low-level cloud type (cloud genus) in the form of individual, detached elements which are generally dense and possess sharp non-fibrous outlines.
Cumulus - Detached clouds, generally dense and with sharp outlines, showing vertical development in the form of domes, mounds, or towers. Tops normally are rounded while bases are more horizontal. See Cb, towering cumulus.

Cumulus A cloud in the form of individual, detached domes or towers that are usually dense and well defined. It has a flat base with a bulging upper part that often resembles cauliflower. Cumulus clouds of fair weather are called cumulus humilis.
Cumulus: A principal cloud type of vertical elements having a flat base and dense, bulging upper portion resembling a heap or pile. The base of cumulus clouds is generally found from 500 to 3000 metres.

Cumulus - One of three basic cloud forms; also the name given one of the clouds of vertical development. Cumulus are billowy, individual cloud masses that often have flat bases.

Cumulus congestus An upward-building convective cloud with vertical development between those of a cumulus cloud and a cumulonimbus cloud.
CUMULUS One of the three basic cloud forms (the others are cirrus and stratus). It is also one of the two low cloud types. A cloud that develops in a vertical direction from the base (bottom) up.

Cumulus Congestus- A large cumulus cloud with great vertical development, usually with a cauliflower-like appearance, but lacking the characteristic anvil shaped top of a Cb.
Cumulus Cloud (Cu) These clouds form in convective currents and are characterized by relatively flat bases and dome-shaped tops. Fair weather cumulus do not show extensive "towers" or vertical development and do not produce precipitation.
ALTOCUMULUS Composed of flattened, thick, gray, globular masses, this middle cloud genus is primarily made of water droplets. In the mid-latitudes, cloud bases are usually found between 8,000 and 18,000 feet.
Altocumulus Standing Leticular (ACSL): These clouds are formed on the crests of waves crested by barriers in the wind flow. The clouds show little movement hence the name standing. Wind, however, can be quite strong blowing through the cloud.
Altocumulus
A cloud of a class characterized by globular masses or rolls in layers or patches, the individual elements being larger and darker than those of cirrocumulus and smaller than those of stratocumulus.
stratocumulus - (Abbreviated Sc.) A principal cloud type (cloud genus), predominantly stratiform, in the form of a gray and/or whitish layer or patch, which nearly always has dark parts and is nonfibrous (except for virga).
Stratocumulus
(Sc) Low-level clouds, existing in a relatively flat layer but having individual elements. Elements often are arranged in rows, bands, or waves.

Cumulus of fair weather
A cloud is a visible mass of condensation droplets or ice crystals suspended in the atmosphere above the surface of the Earth or another planetary body.
Cumulus: a cloud of a class characterized by dense individual elements in the form of puffs, mounds or towers, with flat bases and tops that often resemble cauliflower and found at a lower altitude than altocumulus, usually below 8000 ft (2400 m).
Cumulus - Piled and puffy pillow clouds, nice day clouds with flat bottoms and cotton-ball tops. White with perhaps a touch of grey.
Fog - A cloud that touches the ground or water surface.
Cumulus Clouds - Fluffy, mid-level clouds that develop in towering shapes and signal fair weather. Cumulus clouds are a principle cloud type.
CUMULUS CLOUDS - Puffy clouds caused by small areas of lifting air.

CirrocumulusA cirriform cloud characterized by thin, white patches, each of which is composed of very small granules or ripples. These clouds are of high altitude (20,000-40,000 ft or 6000 -12,000 m).
Several air mass thunderstorms will form, or a line of towering cumulus clouds with showers. At the beach, there are blue skies and a light breeze. This often occurs along the coast of the Gulf of Mexico and Flordia's east coast.
This can sometimes be inferred by a change in humidity (it should 'feel' more humid), and there may be a line of precursor cumulus development, with a change in visibility and wind direction perhaps.
Clouds fall into two general categories: sheetlike or layer-looking stratus clouds (stratus means layer) and cumulus clouds (cumulus means piled up). These two cloud types are divided into four more groups that describe the cloud's altitude.
Clouds can be categorized into two general groups: cumulus clouds (tall, cotton ball) and stratus clouds (layered); these can be divided even further to 4 sub-groups describing altitude: 20, ...
When vapor, water and ice are simultaneously present in a cirrocumulus cloud of supercooled water droplets, the droplets evaporate in favor of ice crystals because of the difference in vapor pressure, ...
However, meteorologists (who think differently from normal people) readily associate these letters with the international observation code for altocumulus clouds. These are common summertime clouds which form in the middle layers of the atmosphere.
Describes the vertical air motion that occur when the atmosphere is unstable. Convection often gives rise to the formation of convective cloud (Cumulus, Towering Cumulus and Thunderclouds) and showery precipitation.

ACCAS (usually pronounced ACK-kis) - AltoCumulus CAStellanus; mid-level clouds (bases generally 8 to 15 thousand feet), of which at least a fraction of their upper parts show cumulus-type development.
Shower - Intermittent rainfall of short duration that falls from a cumulus cloud. Heavy precipitation is possible. Implies more of a scattered rainfall.
Remnant Low: Used for systems no longer having convection required of a tropical cyclone (e.g., the swirls of stratocumulus in the eastern North Pacific).
Meteorologists refer to vertical motions as convective. Horizontal motions are advective. Also used to denote the presence of cumulus clouds (also known as convective clouds); most often refers to instability.
