Cirrostratus fibratus

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] They are formed from strong, continuous winds blowing at high altitudes, and they often cover a large portion of the sky.^[5] Cirrostratus fibratus may often develop from either cirrus fibratus or cirrus spissatus cloud.^[6] Precipitation is often imminent behind these clouds; however, they are not a precipitation-producing cloud.^[7]
