Dark blue cloudy sky

What is Altocumulus?

A middle cloud type within the B family in the international cloud classification. These are shaded clouds that can be white or gray, forming a layer or patches. They have thin and translucent edges and can be observed at several different levels simultaneously. Altostratus clouds can change into altocumulus shapes during the day and persist throughout the day. They typically appear wispy and diffuse. In mid-latitudes, the cloud base is between 8,000 and 18,000 feet. This cloud type has subtypes such as altostratus castellanus or altostratus lenticularis, cumulogenitus, floccus, opacus, translucidus, undulatus, and Virga.
