Clouds that exhibit vertical growth and are caused by convective processes.
A principal cloud type in the form of individual, detached elements which are generally dense and possess sharp non-fibrous outlines.
A type of cloud form with massive or globular appearance.
Clouds with a woolly, heaped appearance that often produce rain.
Puffy clouds which mark unstable air and can be found at any level in the atmosphere
A principal cloud type, appearing as individual fluffy white puffs with gray flat bases. Cumulus are formed by vertical air currents associated with daytime heating.
These clouds have a flat base and a dense, mound shaped top that resembles a large cauliflower. Where the sun hits these clouds they are a brilliant white.
A type of cloud formation. These are billowy clouds, often described as "cottonballs".
A form of cloud consisting of rounded masses heaped on horizontal base.
A cloud in the form of individual, detached domes or towers that are usually dense and well defined.
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. They have flat bases and dome- or cauliflower-shaped upper surfaces. The base of the cloud is often no more than 3,000 feet above the ground, but the top often varies in height. Small, separate cumulus are associated with fair weather (cumulus humilis). With additional heating from the earth's surface, they can grow vertically throughout the day. The top of such a cloud can easily reach 20,000 or more into the troposphere. Under certain atmospheric conditions, these clouds can develop into larger clouds, known as towering cumulus (cumulus congestus), and may produce a rain shower. Further development may create a cumulonimbus.
a puffy white cloud formed by rising air heated by the sun
cloud type in the form of individual, detached elements which are generally dense, have well-defined outlines, show vertical development in the form of domes, mounds, or towers
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.
The sticky white cloud-like clump of cells that develops around the egg just prior to ovulation and which accompanies it during and after ovulation or aspiration.
Fair-weather clouds with broad horizontal bases, producing no precipitation and rarely covering more than one-half of the sky.
Cauliflower-shaped clouds associated with showery-type precipitation. They may appear to be tall and towering or tall and broad, and can be either isolated or grow from lower lines or decks of cloud.
Detached cloud, generally dense and with sharp outlines, developing vertically in the form of rising mounds, domes, or towers, of which the bulging upper part is often like a cauliflower. The sunlit parts are mostly brilliant white and the base is relatively dark and nearly horizontal. Sometimes Cumulus clouds are ragged.
Type of cloud formed in puffs or dome shaped.
A principal, low cloud-type in the form of individual cauliflower-like cells of sharp non-fibrous outline and less vertical development than cumulonimbus.
