A middle cloud, usually white or gray. Often occurs in layers or patches with wavy, rounded masses or rolls.

White or gray layers or patches of cloud, often with a waved appearance; cloud elements appear as rounded masses or rolls; composed liquid water droplets which may be supercooled; may contain ice crystals at subfreezing temperatures.

(n) a cumulus cloud at an intermediate altitude of 2 or 3 miles

a middle cloud type that is white and/or gray in color and occurs as a layer or patch with a waved aspect. Generally have shadowed parts.

These clouds are composed of mainly water. They appear as white or gray colored roll like elements or bands. The individual elements are large and darker than in cirrocumulus clouds. These clouds from between 6,500 and 23,000 feet.

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. These clouds are of medium altitude, about 8000-20,000 ft (2400-6100 m).

Grey to white clouds that form in groups or globular masses and look like rolls in layers or patches. When holding your extended hand to the sky, they are about the size of your thumb. Alto means high while cumulus means heap and signifies convection. These clouds often resemble "sheepback", usually forming after a cold front. But on a wa [..]

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. A defining characteristic is that it often appears as a wavy billowy layer of cloud, giving it the nickname of "sheep" or "woolpack" [..]

(Ac) Mid-level cloud (bases generally 2000 - 8000m), made up of grey, puffy masses, sometimes appearing in parallel waves or bands. An indicator of mid-level instability. Altocumulus can take on various forms such as Ac Lenticularis, Ac Undulatus, Ac Castellanus, Altocumulus 'mackerel sky'.

A middle cloud, usually white or gray. Often occurs in layers of patches with wavy, rounded masses or rolls.

A layer of cumulus cloud at medium levels, 7000ft and above (formed largely of water droplets with some ice crystals)

Mid-altitude

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.

Composed of flattened, thick, gray, globular masses, this middle cloud

A type of middle cloud, ranging from about 2500 to 6000m high in the atmosphere, that has a little bit of vertical extent. Will usually look a little puffy, blobby or patchy.
