These are made when the cloud takes the form of thin cirrostratus nebulosus. [1] The cloud has a fibrous texture with no halos if it is thicker cirrostratus fibratus. On the approach of a frontal system, the cirrostratus often begins as nebulous and turns to fibratus. If the cirrostratus begins as fragmented of clouds in the sky it often means ...
Clouds of the genus nimbostratus tend to bring constant precipitation and low visibility. This cloud type normally forms above 2 kilometres (6,600 ft) [10] from altostratus cloud but tends to thicken into the lower levels during the occurrence of precipitation. The top of a nimbostratus deck is usually in the middle level of the troposphere.
Cirrostratus nebulosus is one of the two most common forms that cirrostratus often takes, with the other being cirrostratus fibratus. The nebulosus species is featureless and uniform, while the fibratus species has a fibrous appearance. [3] Cirrostratus nebulosus are formed by gently rising air. The cloud is often hard to see unless the sun ...
Cirrostratus cloud. Cirrostratus clouds can appear as a milky sheen in the sky [72] or as a striated sheet. [67] They are sometimes similar to altostratus and are distinguishable from the latter because the Sun or Moon is always clearly visible through transparent cirrostratus, in contrast to altostratus which tends to be opaque or translucent ...
Cirrostratus fibratus or also called Cirrostratus filosus [2] is a type of cirrostratus cloud. The name cirrostratus fibratus is derived from Latin , meaning "fibrous". [ 3 ] Cirrostratus fibratus is one of the two most common forms that cirrostratus often takes, with the other being cirrostratus nebulosus . [ 4 ]
Cirrus radiatus is a variety of cirrus cloud.The name cirrus radiatus is derived from Latin, meaning "rayed, striped". [1] This variety of cirrus clouds occurs in parallel bands that often cover the entire sky and appear to converge at a single point [2] or two opposite points on the horizon.
A mackerel sky is a term for clouds made up of rows of cirrocumulus or altocumulus clouds displaying an undulating, rippling pattern similar in appearance to fish scales; [1] [2] this is caused by high altitude atmospheric waves. [3]
