Cirrus radiatus

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. Cirrus radiatus is often partly made up of cirrocumulus or cirrostratus.^[3]
