Next Topic: Cirrostratus Clouds

Cirrocumulus clouds form at high altitudes (usually around 5 km) and have distinguishing characteristics displayed in a fine layer of small cloud patches. These small cloud patches are sometimes referred to as "cloudlets" in relation to the whole cloud formation.

Cirrocumulus clouds are formed from ice crystals and water droplets. Often, the water droplets in the cloud freeze into ice crystals and the cloud becomes a cirrostratus cloud. Because of this common occurrence, cirrocumulus cloud formations generally pass rapidly.
