Cirrostratus Clouds sheet-like and nearly transparent
Cirrostratus are sheet-like, high-level clouds composed of ice crystals.
Cirrostratus (Cs) A principal high-level cloud type (cloud genus), appearing as a transparent, whitish cloud veil of fibrous (hair-like) or smooth appearance, totally or partially covering the sky, and often producing halo phenomena, ...
cirrostratus"(Abbreviated Cs.) A principal cloud type (cloud genus), appearing as a whitish veil, usually fibrous but sometimes smooth, that may totally cover the sky, and that often produces halo phenomena, either partial or complete.
Cirrostratus
High level, transparent sheet or white veil, not rippled like cirrocumulus. Causes a halo (ring) to form around the sun.
Cirrostratus (Cs): Layered high clouds that are whitish in color and usually fibrous, but sometimes smooth, in appearance. Cirrostratus often produce optical effects such as halos.
CIRROSTRATUS: Cirrus clouds with a flat sheetlike appearance.
CIRRUS: High clouds, usually above 18,000 feet, composed of ice crystals.
CLEAR: Sky condition of less than 1/10 cloud coverage.
Cirrostratus - a high-level cloud which is composed mostly of ice crystals and has the appearance of a whitish veil which may totally cover the sky ...
Cirrostratus
(Cs) High, thin, sheet like clouds that often cover the entire sky. Composed of ice crystals, they are often the cause of halos around the sun or moon.
Cirrostratus ...
Cirrostratus A high cloud appearing as a whitish veil that may totally cover the sky. Often produces halo phenomena.
CIRROSTRATUS A cirriform cloud that develops from cirrus spreading out into a thin layer, creating a flat sheetlike appearance. It can give the sky a slightly milky or veiled look.
Cirrostratus
Transparent, whitish cloud veil of fibrous (hair-like) or smooth appearance totally or partially covering the sky, and generally producing halo phenomena.
Cirrostratus cloud (Cs) A high, thin, layered cloud composed of ice crystals that forms a thin white veil over the sky.
Cirrus cloud (Ci) A high thin cloud occurring as silky strands and composed of ice crystals.
Cirrostratus (Cs) They are thin, whitish cloud layers appearing like a sheet or veil. They are diffuse sometimes partially striated or fibrous.
Cirrostratus High, thin, sheetlike clouds, composed of ice crystals. They frequently cover the entire sky and often produce a halo.
Cirrostratus
A cloud of a class characterized by a composition of ice crystals and often by the production of halo phenomena and appearing as a whitish and usually somewhat fibrous veil, ...
CIRROSTRATUS: A principal cloud type featuring cirrus clouds with a flat or sheet-like appearance.
CLEAR: Sky condition with less than 1/10 cloud coverage.
CLIMATE: The statistical collective of weather records during a specified period of time.
Cirrostratus - Thin high sheet clouds.
Cirrus - Wispy white feathers high up in the air.
Cumulonimbus - Cumulus + Nimbus (giving precipitation). Very high piles of cloud, dark and mysterious and lead to thunderstorms.
They include all varieties of cirrus, cirrocumulus, and cirrostratus clouds. CIRROCUMULUS A cirriform cloud with vertical development, appearing as a thin sheet of small white puffs which give it a rippled effect.
High cloudCirrus, cirrostratus and cirrocumulus. High risk (of severe thunderstorm)Severe weather is expected to affect more than 10 percent of the area.
Solar Halo: A ring around the Sun produced by cirrostratus clouds which consist of ice crystals Solar Wind: Is produced by charged ion particles escaping from the Sun. Solar Wind: The solar wind moves on average about 400 kilometers per sec/ 250 mps.
Some clouds at this level are cirrus, cirrocumulus, and cirrostratusHigh Energy EventIn solar-terrestrial terms, flares (class two or more) with outstanding Centimetric Bursts and SID.
cirrostratusA cloud belonging to a class characterized by a composition of ice crystals and often by the production of halo phenomena.
A sundog is a relatively common atmospheric optical phenomenon associated with the reflection/refraction of sunlight by the numerous small ice crystals that make up cirrus or cirrostratus clouds.
There are many cirrus type clouds such as CIRROSTRATUS and CIRROCUMULUS. The word "cirrus" comes from the Greek word meaning wispy.
cirrostratus (high altitude flat, layerd cloud)
a large halo closely circles the sun or moon shining through cirrostratus
cirrocumulus (high altitude puffy clouds) ...
It often merges gradually into cirrostratus. As with cirrostratus, it often is part of a cloud shield associated with a front. This type of cloud is composed of mainly water vapor and result from lifting a layer.
into two general groups: cumulus clouds (tall, cotton ball) and stratus clouds (layered); these can be divided even further to 4 sub-groups describing altitude: 20,000 ft and above are the cirrus or cirro clouds (cirrocumulus, cirrostratus), ...
A cloud of a class characterized by a generally uniform gray sheet or layer, lighter in color than nimbostratus and darker than cirrostratus. These clouds are of medium altitude, about 8000 to 20,000 ft (2400-6100 m).

Abbreviation for Altostratus, a cloud of a class characterized by a generally uniform gray sheet or layer, lighter in color than nimbostratus and darker than cirrostratus. These clouds are of medium altitude, about 8000 to 20,000 ft (2400-6100 m).
We now know that they are the optical result of the refraction of light from the sun or moon by ice crystals in the very high cloud (9,000 meters) called cirrus or cirrostratus.
stratiform - Descriptive of clouds of extensive horizontal development, as contrasted to the vertically developed cumuliform types. See stratus, altostratus, cirrostratus, nimbostratus, stratocumulus.
high clouds: clouds found between 3-8 kilometers (10000-25000 feet) in polar regions and 6-18 kilometers (20000-60000 feet) in tropical regions. Contains cirriform clouds (cirrus, cirrocumulus, and cirrostratus).
In the 'Medium' cloud class come: Altostratus (As); Altocumulus (Ac) and Nimbostratus (Ns). Nimbostratus often has a base within the 'low' cloud category.
In the 'High' cloud group are: Cirrus (Ci); Cirrocumulus (Cc) and Cirrostratus (Cs).
The clouds tend to be wispy, are often transparent, and include cirrus, cirrocumulus, and cirrostratus. Middle clouds form between 6,500 and 20,000 feet and are denoted by the prefix ALTO.
