Explanatory remarks

(Section 2.3.7.8)

The appearance of Stratocumulus is similar to that of Altocumulus. Owing to its generally lower height, the elements of Stratocumulus look larger and, at times, smoother than those of Altocumulus.

Stratocumulus elements are often arranged in lines or groups, showing a single or double system of undulations. Elements may be more or less separate; however, the cloud layer is more often continuous, sometimes with gaps. The undersurface of a continuous cloud layer is often uneven and presents a relief in the form of creases, mamma, etc.
