cirrus

Thin, separated or detached clouds appearing in all seasons. They are often feathery, fibrous, or tufted in appearance. They are high clouds, which occur at above 20,000 ft (6 km) height. Cirrus clouds are composed of thin crystals or needles of ice, not droplets of water. These clouds are represented on the weather map by symbols like and . The former means that the amount of cirrus is not increasing, whereas the latter means that it is a dense cirrus cloud but it does not form an anvil of a cumulonimbus cloud.
