What type of cloud is cirrostratus?
Weather prediction: A change is on its way! Cirrostratus clouds are thin, white clouds that cover the whole sky like a veil. These clouds are most commonly seen in the winter, and can cause the appearance of a halo around the sun or the moon. Weather prediction: Rain or snow will arrive within 24 hours!
What causes cirrostratus clouds to form?
Cirrostratus are sheet-like, high-level clouds composed of ice crystals. These high-level clouds typically form when a broad layer of air is lifted by large-scale convergence. Photograph by: Rauber. Sometimes the only indication of their presence is given by an observed halo around the sun or moon.
What are cirrus and cirrostratus clouds made out of?
ice crystals
The three main types of high clouds are cirrus, cirrostratus, and cirrocumulus. Cirrus clouds are wispy, feathery, and composed entirely of ice crystals. They often are the first sign of an approaching warm front or upper-level jet streak.
What does a cirrus cloud made of?
Cirrus is made up completely of ice crystals, which provides their white colour and form in a wide range of shapes and sizes. Cirrus clouds can also form through contrails, the vapour trails left by planes as they fly through a dry upper troposphere.
What level is a cirrostratus cloud?
| Cirrostratus cloud | |
|---|---|
| Altitude | 6,000 – 13,000 m (20,000 – 43,000 ft) |
| Classification | Family A (High-level) |
| Appearance | Thin, transparent, high-altitude layer capable of producing a halo. |
| Precipitation cloud? | No, but usually signal the approach of a warm front. |
Are cirrostratus clouds stable?
Cirrus cloud layers are in general statically stable in an absolute sense, with lapse rates less than the moist-adiabatic rates with respect to either water or ice. Some cirrus clouds are located above stable layers, indicating that they are associated with upper-level fronts.
What kind of weather does a cirrus cloud bring?
Cirrus clouds are the most common of the high clouds. They are composed of ice and are thin, wispy clouds blown in high winds into long streamers. Cirrus clouds are usually white and predict fair to pleasant weather….

Is the cirrostratus cloud made of ice crystals?
Cirrostratus / ˌsɪroʊˈstrɑːtəs / is a high-level, very thin, generally uniform stratiform genus-type of cloud. It is made out of ice -crystals, which are pieces of frozen water. It is difficult to detect and it can make halos.
What kind of cloud is composed of ice crystals?
Cirrostratus /ˌsɪroʊˈstrɑːtəs/ is a high-level, very thin, generally uniform stratiform genus-type of cloud, composed of ice-crystals. It is difficult to detect and is capable of forming halos when the cloud takes the form of thin cirrostratus nebulosus.
When do cirrostratus clouds indicate a warm front?
Cirrostratus cloud. Cirrostratus clouds sometimes signal the approach of a warm front if they form after cirrus and spread from one area across the sky, and thus may be signs that precipitation might follow in the next 12 to 24 hours or as soon as 6–8 hours if the front is fast moving. If the cirrostratus is broken fibratus,…
What is the difference between cirrostratus and genitus?
Supplementary features: Cirrostratus produces no precipitation or virga, and is not accompanied by any accessory clouds. Genitus mother clouds: Cirrostratus fibratus cirrocumulogenitus sometimes appears as the latter cloud flattens and loses some of its stratocumuliform structure.
