Unlike cirrus, cirrostratus clouds form more of a widespread, … WebMay 27, 2024 · The DR values associated with different shapes of ice crystals exist within the cirrus cloud around 12 km . High altitude cirrus clouds with larger DR values of > 0.3, moderate values of DR in the order of 0.3, and lower DR values of < 0.3 indicate the presence of different compositions of ice crystals present in cirrus clouds .
WebIn this fourth of a series of papers that describe long-term cloud research at the Facility for Atmospheric Remote Sensing at Salt Lake City, Utah, an ∼10-year record of polarization lidar and photographic observations is analyzed to characterize the occurrence of optical displays in our local varieties of midlatitude cirrus clouds. The frequencies of … WebLiquid clouds form at low altitudes, but clouds can also form high in the atmosphere. High, or cirrus, clouds form at cold temperatures (colder than -30 °C or -22 °F) and are composed of ice crystals instead of liquid droplets.

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. Globally, they form … See more Cirrus are wispy clouds made of long strands of ice crystals that are described as feathery, hair-like, or layered in appearance. First defined scientifically by Luke Howard in an 1803 paper, their name is derived from the See more Cirrus clouds cover up to 25% of the Earth (up to 70% in the tropics at night ) and have a net heating effect. When they are thin and translucent, the clouds efficiently absorb outgoing infrared radiation while only marginally reflecting the incoming sunlight. When … See more Cirrus clouds can produce several optical effects like halos around the Sun and Moon. Halos are caused by interaction of the light with hexagonal ice crystals present in the … See more Cirrus clouds are one of three different genera of high-level clouds, all of which are given the prefix "cirro-".
