Cirrostratus with Halo
The upper right of the picture shows a cirrus cloud with some indication of puffiness (i.e., cirrocumulus); and the lower left of the photo has what looks like some thick low level cloudiness. But the portion of the photo where the sun is shining is a nice uniform cirrostratus, with the bonus of showing the prismatic effect of ice clouds on sunlight. Photo from Dr. Francisco Vazquez Colon School, Manati, Puerto Rico. 3rd place (tie) in January 2003 S'COOL Cloud Photo contest.
Cirrostratus in California
The cloud in this photo is remarkably similar to the previous photo, but without the lower layer. The middle of the photo shows a nice uniform cirrostratus layer. Photo from St. Anne School, Porterville, California. 3rd place (tie) in January 2003 S'COOL Cloud Photo contest.
Cirrostratus with Stratus
Well, what's not to like? This photo has a great top view of a low level stratus cloud (might even be fog), with a nice distinct layer of cirrostratus off in the distance. Photo from Peru Central School, Peru, New York. Multilayer winner in January 2003 S'COOL Cloud Photo contest.
Cirrostratus at Night
Night-time cloud watching has its challenges, but this photo captures the moon just as it illuminates a nice stratus section of the cloud. This is probably cirrostratus (ice cloud) because of the rainbow effect around the moon, but could also be altostratus. Photo from Sant Antoni Abat School, Valencia, Spain. Night-time winner in January 2003 S'COOL Cloud Photo contest.
