Cirrus ice crystal clouds
WebAt the top of the convective clouds are cirrus clouds made of ice crystals. These crystals effect weather and climate in two ways: first, depending on the ice crystal's shape, it affects the amount of Sun's energy reflected … WebCirrocumulus – High clouds with a puffy, patchy appearance and small spaces between clouds. Often form wave-like patterns. Cirrostratus – High clouds, light gray or white, …

Did you know?
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-". The other two genera are cirrocumulus and cirrostratus. High-level clouds … See more Cirrus clouds are usually formed as warm, dry air rises, causing water vapor to undergo deposition onto rocky or metallic dust particles at … See more Random, isolated cirrus do not have any particular significance. A large number of cirrus clouds can be a sign of an approaching frontal system or upper air disturbance. The appearance of cirrus signals a change in weather—usually more stormy—in … See more Scientists have studied the properties of cirrus using several different methods. Lidar (laser-based radar) gives highly accurate information on the cloud's altitude, length, and width. Balloon-carried hygrometers measure the humidity of the cirrus cloud but are … See more WebMar 4, 2013 · The ice crystals of cirrus clouds generally form spontaneously in moist, cold air. But seed particles, if present in the right concentration, could grab all the water vapour to produce a small ...
WebSep 4, 2013 · Cirrus clouds are high, cold clouds composed of ice crystals. In the tropics, cirrus form at altitudes of about 30,000 to 60,000 feet (9-18 km). Among other mechanisms, tropical cirrus are generated at the tops of cumulonimbus clouds. These deep convective clouds pump water vapor and ice crystals to the upper troposphere creating the … WebFeb 28, 2024 · This can happen because of something called cloud iridescence. It usually happens in altocumulus, cirrocumulus, lenticular and cirrus clouds. Iridescent clouds …
