What does cirrostratus cloud indicate?
What weather is associated with cirrostratus clouds? Though cirrostratus itself does not produce precipitation, it can indicate whether or not precipitation is likely. If cirrostratus nebulosus exists in the sky it is likely that an incoming warm front will bring persistent rain within a day.
What are the characteristics of a cirrostratus cloud?
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. Unlike cirrus, cirrostratus clouds form more of a widespread, veil-like layer (similar to what stratus clouds do in low levels).
What causes cirrostratus clouds?
Weather Patterns Causing Cirrostratus Clouds Cirrostratus clouds often form when a warm front, a mass of warmer air, moves up and over colder air. The warmer air holds more water vapor than the colder air.
How long do cirrostratus clouds last?
Due to a definition that allows no shading, cirrocumulus clouds are very thin (less than 200 m thick), and usually very short-lived, often appearing and disappearing in minutes.
What kind of weather do cumulonimbus clouds bring?
Cumulonimbus clouds are associated with extreme weather such as heavy torrential downpours, hail storms, lightning and even tornadoes. Individual cumulonimbus cells will usually dissipate within an hour once showers start falling, making for short-lived, heavy rain.
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 are cirrus fibratus clouds?
Cirrus fibratus clouds are usually thicker, individualized cloud strands that look like individual locks of hair. In this case, the entire sky is blanketed with these clouds.
What is the scientific name for cirrostratus fibratus?
Cirrostratus fibratus. Cirrostratus fibratus is a type of cirrostratus cloud. The name cirrostratus fibratus is derived from Latin, meaning “fibrous”. Cirrostratus fibratus is one of the two most common forms that cirrostratus often takes, with the other being cirrostratus nebulosus.
What are the characteristics of cirrostratus clouds?
Cirrostratus clouds are only associated with two cloud varieties: duplicatus and undulatus. Duplicatus means there are two layers of cirrostratus clouds found at different altitudes. In our case, it appears the cloud is one fibered, uniform layer. The cloud doesn’t appear to be wavy and undulating either.
