High altitude cloud (6,000 to 12,000m) composed of ice crystals with a delicate and whispy appearance.

A high cloud made of ice crystals. Often thin, white, and in narrow bands.

a wispy white cloud (usually of fine ice crystals) at a high altitude (4 to 8 miles)

Thin, wispy clouds which form at the upper layer of the atmosphere and are composed mostly of ice crystals

A principal cloud type, appearing as thin white feathery elements, composed entirely of ice crystals, and found at the top of the troposphere between 30,000 and 50,000 feet.

These clouds contain ice crystals and generally look like white wispy feathers.

A type of cloud formation. These are high, thin clouds that look like wisps of cotton candy.

A giant thunder cloud that towers to gray heights usually there are thunder storms, heavy rain, hail, and lightning.

Clouds made up of ice crystals, occurring at a height of between 15,000 and 45,000 feet.

A high cloud composed of ice crystals in the form of thin, white, featherlike clouds in patches, filaments, or narrow bands.

A form of high cloud, composed of ice crystals, which seldom obscures the sun.

One of the three basic cloud forms (the others are cumulus and stratus). It is also one of the three high cloud types. Cirrus are thin, wispy clouds composed of ice crystals and often appear as veil patches or strands. In the mid-latitudes, cloud bases are usually found between 20,000 to 30,000 feet, and it is the highest cloud that forms in the sky, except for the tops, or anvils, of cumulonimbus, which occasionally build to excessive heights.

a cloud that forms in wispy strands high in the sky

a high-level cloud (16,000 feet or more) which is composed mostly of ice crystals and has the appearance of white, delicate filaments in patches or narrow bands

High-level clouds (16,000 feet or more), composed of ice crystals and appearing in the form of white, delicate filaments or white or mostly white patches or narrow bands. Cirrus clouds typically have a fibrous or hairlike appearance, and often are semi-transparent. Thunderstorm anvils are a form of cirrus cloud, but most cirrus clouds are not associated with thunderstorms.

High clouds, usually above 18,000 feet, composed of ice crystals.

High, thin clouds composed of mainly ice particles.

High, white patches of cloud composed of ice crystals, found at altitudes of 6,000 meters or higher.Fine and delicate in appearance, their shape and texture are often described as looking like mares' tails. In forecasts they are referred to as high cloud.

Detached clouds in the form of white, delicate filaments or white or mostly white patches or narrow bands. These clouds have a fibrous (hair-like) appearance, or a silky sheen, or both.
