Cirrostratus fibratus, also called cirrostratus filosus, [1] is a type of cirrostratus cloud. The name cirrostratus fibratus is derived from Latin, meaning "fibrous". [2] Cirrostratus fibratus is one of the two most common forms that cirrostratus often takes, with the other being cirrostratus nebulosus. [3] They are formed from strong, continuous winds blowing at high altitudes, and they often cover a large portion of the sky. [4] Cirrostratus fibratus may often develop from either cirrus fibratus or cirrus spissatus cloud. [5] Precipitation is often imminent behind these clouds; however, they are not a precipitation-producing cloud. [6]
