Stratocumulus Clouds (Low Cloud Group)
Picture by Carlye Calvin/UCAR
These clouds are low, lumpy, and gray. They sometimes they line up in rows and other times they spread out.
Only light precipitation, generally in the form of drizzle, occurs with stratocumulus clouds.
To distinguish between a stratocumulus and an altocumulus cloud, point your hand toward the cloud. If the cloud is about the size of your fist, then it is stratocumulus.
