- Different clouds above and below. Tops of mountain ridges interrupt a sea of valley Stratus clouds, seen from above. The low cloud layer is being warmed by sunshine and a few cumuliform tufts are beginning to rise as the sheet transforms slowly into Stratocumulus before breaking up and evaporating. A few strips of Altocumulus (top right) appear dark below a white, higher Ac sheet.
