Cirrocumulus lacunosus is a type of cirrocumulus cloud. Cirrocumulus stratiformis is a type of cirrocumulus cloud. Cirrocumulus lenticularis is a type of cirrocumulus cloud. Cirrocumulus floccus is a type of cirrocumulus cloud. They are usually more widely spaced than the bands or elements seen with cirrocumulus clouds. Cirrus radiatus is often partly made up of cirrocumulus or cirrostratus. It is a cloud species attached to the cloud genera cirrus, cirrocumulus, altocumulus and stratocumulus. They are sometimes seen with cirrus, cirrocumulus, altocumulus, and stratocumulus. There are three main genera in the family of high clouds&colon; cirrus, cirrocumulus, and cirrostratus. The other two genera, cirrocumulus and cirrostratus, are also high clouds. Thus cirrocumulus clouds are usually short-lived. This fairly common phenomenon is most often observed in altocumulus, cirrocumulus, lenticular, and cirrus clouds. Like lower altitude cumuliform and stratocumuliform clouds, cirrocumulus signifies convection.
