There two types of Altocumulus in this photo and probably also altostratus. The altocumulus include small cloud cells and also lens-shaped clouds called altocumulus lenticularis.

These developing clouds are individual cells in a cluster. Shortly after this photo was taken the cells dissipated, never to be seen again.

Behind the tree tops is a dark cylinder shaped cloud. It’s name is altocumulus lenticularis. It has vertical structure so it is a type of cumulus, it is in the mid-levels (altocumulus) and it is lens-shaped. The complete name is altocumulus lenticul…

The setting sun reveals the three dimensional shape of this mid-level cloud layer. As a cumulus cloud type in the mid-levels it is altocumulus.

Here is another look at the altocumulus at sunset.

Here is another look at the altocumulus at sunset.

Altocumulus form as individual cells, in patterns, and in rows. These altocumulus from in rows when waves in the air cause up and down motion. The layer is marginally unstable giving the clouds vertical shape.

And…a final look at Altocumulus at Sunset. Notice the waves in two directions and individual cloud cells.
