- Mixed cloud type layers. The base of a distant Cumulonimbus cloud provides a dark background for the closer low Cumulus clouds as well as a few Altocumulus patches. Other Ac patches at the same level appear darker than the cirriform, white anvil, or are crumbly (top). A separate, small Ac patch is at a higher level (upper left).
