Cell - Convection in the form of a single updraft, downdraft, or updraft/downdraft couplet, typically seen as a vertical dome or tower as in a cumulus or towering cumulus cloud.
Fair Weather Cumulus Clouds puffy cotton balls floating in the sky
Fair weather cumulus have the appearance of floating cotton and have a lifetime of 5-40 minutes.
Cumulus Cloud - A column of rising air that has condensed into a dense, nonfibrous cloud with distinct outlines, appearing much like a rising mound or dome.
CUMULUS CLOUD (Cu): A cloud in the shape of individual detached domes, with a flat base and a bulging upper portion resembling cauliflower.
CUT OFF LOW: An area of low pressure cut off from its associated jet stream.
Cumulus clouds (Cu) Clouds that develop as a consequence of the updraft in convection currents; resemble huge puffs of cotton floating in the sky.
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.
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.

Cumulus clouds - 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 clouds with little or no vertical development characterized by a generally flat appearance. Their growth is usually limited by a temperature inversion, which is marked by the unusually uniform height of the clouds.
Altocumulus cloud as seen from the space shuttle. Altocumulus is formed through convective activity.
A large cumulus cloud with great vertical development, usually with a cauliflower-like appearance, but lacking the characteristic anvil of a Cb. (Often shortened to "towering cu," and abbreviated TCU.)

Fractocumulus: a cumulus cloud presenting a ragged, shredded appearance, as if torn.Fractostratus: a stratus cloud presenting a ragged, shredded appearance, as if torn.
CUMULONIMBUS - A cumulus cloud that has precipitation associated with it. The term CUMULO is Latin derived meaning "heaped up" and NIMBUS is Greek derived word for "rain". Cumulonimbus clouds can occur at any altitude and often vertically developed.
chimney cloud"A cumulus cloud that has much greater vertical than horizontal extent.
Congestus (or 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 (Cumulonimbus cloud).
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.
Flanking LineA line of cumulus or towering cumulus clouds connected to and extending outward from the most active part of a supercell, normally on the southwest side.
If the air is sufficiently moist, then the moisture condenses to become a cumulus cloud or an individual tower of a towering cumulus or Cb.
Cbs, towering cumulus clouds, and ACCAS clouds all are visible forms of convection. However, convection is not always made visible by clouds.
Under certain conditions cumulus clouds may be arranged in files, cloud streets, oriented approximately parallel to the wind direction. Changes in direction of illumination and in background cause modification of color and of apparent surface relief.

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, ...
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.
A line of cumulus or towering cumulus clouds connected to and extending outward from the most active part of a thunderstorm, normally on the northwest side.
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, ...
It can form from cumulus clouds becoming more stratiformed and often appears as regularly arranged elements that may be tessellated, rounded, or roll-shaped with relatively flat tops and bases.
ROTOR CLOUD An altocumulus cloud formation that can be found in the lee of a mountain or similar barrier. The air rotates around a horizontal axis, creating turbulence. Altocumulus lenticularis is an example.
Towering cumulus - A cumulonimbus in the making. High piled cumulus cloud.
Continental climate - a drier climate with great temperature extremes throughout the year.
Convection - Air moving up and down in a quasi-circular flow, called a cell.
Altocumulus lenticularis A lens-shaped altocumulus cloud; a mountain-wave cloud generated by the disturbance of horizontal airflow caused by a prominent mountain range.
Waterspout: A type of whirlwind that forms underneath cumulus clouds over a large body of water.
Watt: A unit of power or energy per unit time.
Wavelength: The distance between one crest of a wave and another.
The base of cumulus clouds is generally found from 500 to 3000 metres. Large cumulonimbus clouds may extend to over 18,000 metres and be topped with anvil-shaped ice clouds. Cumulus is derived from the Latin for "heap." ...
Shower - Intermittent rainfall of short duration that falls from a cumulus cloud. Heavy precipitation is possible. Implies more of a scattered rainfall.
Unlike tornadoes, whose parent clouds are cumulonimbus (thunderheads) and of great vertical depth, cold air funnels may drop from ordinary cumulus clouds as a result of small scale local instability aloft.
This cloud often forms from stratus as the stratus is breaking up or from spreading out of cumulus clouds. They usually consist of mainly water vapor and are located between the ground and 6,500 feet.
Cumulus stage The initial stage in the development of an air mass thunderstorm in which rising, warm, humid air develops into a cumulus cloud.
Cyclogenesis The development or strengthening of middle latitude (extratropical) cyclones.
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.
Clouds with a woolly appearance are called cumulus. Sometimes they are small low-level clouds. They can also be present during thunderstorms, reaching heights of 15 kilometres. Cumulus clouds often produce shower.
