Unlike cirrus and cirrostratus, cirrocumulus clouds contain droplets of supercooled (below freezing point) water.Ĭirrus clouds form in the atmospheres of Mars, Jupiter, Saturn, Uranus, and Neptune and on Titan, one of Saturn's larger moons. Cirrostratus looks like a sheet of cloud, whereas cirrocumulus looks like a pattern of small cloud tufts. There are two other high-level cirrus-like clouds called cirrostratus and cirrocumulus. Optical phenomena, such as sun dogs and halos, can be produced by light interacting with ice crystals in cirrus clouds. A warming earth will likely produce more cirrus clouds, potentially resulting in a self-reinforcing loop. Cirrus clouds warm the earth, potentially contributing to climate change. These crystals dissipate as they fall through warmer and drier air and never reach ground. Although they are a sign that rain and maybe storms are on the way, cirrus themselves drop no more than falling streaks of ice crystals. Globally, they form anywhere between 4,000 and 20,000 meters (13,000 and 66,000 feet) above sea level, with the higher elevations usually in the tropics and the lower elevations in more polar regions.Ĭirrus clouds can form from the tops of thunderstorms and tropical cyclones and sometimes predict the arrival of rain or storms.

Cirrus are usually formed as warm, dry air rises, causing water vapor deposition onto rocky or metallic dust particles at high altitudes.

Cirrus clouds typically appear delicate and wispy with white strands. Sky containing different types of cirrus cloudsĬirrus ( cloud classification symbol: Ci) is a genus of high cloud made of ice crystals.
