Cirrus ( cloud classification symbol: Ci) is a genus of high cloud made of ice crystals. Cirrus clouds typically appear delicate and wispy with white strands. Cirrus are usually formed when warm, dry air rises, causing water vapor deposition onto rocky or metallic dust particles at high altitudes.
Cirrus spissatus or also called Cirrus densus and Cirrus nothus clouds are the highest of the main cloud genera, and may sometimes even occur in the lower stratosphere. The characteristic features of cirrus clouds are fine threads or wisps of ice crystals, generally white, but

Jun 10, 2017 · What are Cirrus Clouds? Cirrus clouds are formed at high altitudes of 8,000 – 12,000m. They are detached thin clouds. They have a feathery appearance. They are always white. What are Cumulus Clouds? Cumulus clouds are generally formed at a height of 4,000 m – 7,000 m. They look like cotton wool.
Jul 25, 2023 · Cirrus clouds are thin, delicate types of clouds found at high altitudes, typically above 20,000 feet (6,000 meters). They are composed of tiny ice crystals and form in the upper...
Cirrus clouds are short, detached, hair-like clouds found at high altitudes. These delicate clouds are wispy, with a silky sheen, or look like tufts of hair. In the daytime, they...
Cirrus fibratus or also called Cirrus filosus is a species of cirrus cloud. The name cirrus fibratus is derived from Latin, meaning "fibrous". These clouds are similar to cirrus uncinus, commonly known as "mares' tails"; however, fibratus clouds do not have tufts or hooks at the end. The filaments are usually separate from one another. Like ...
Cirrus clouds are composed almost exclusively of ice crystals. These crystals are generally very small, which, together with their sparseness, accounts for the transparency of most Cirrus clouds.
This photo shows transparent to translucent cirrus streaks, and illustrates why cirrus clouds are often described as mare's tails. The streaks come from falling ice particles that make up the clouds. Photo by Lin Chambers, August, 2002.
Definition of Cirrus. 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.
