The dramatic clouds - altocumulus lenticularis
- are usually found in mountainous regions due to very specific atmospheric conditions.
Divided into sections devoted to low, middle, and high clouds, this field guide to the sky includes such details as that cumulonimbus clouds are ferocious storm producers, that altocumulus lenticularis
clouds look like UFOs, and that cirrostratus clouds have a tendency for form halos.
The cloud types shown on the stamp pane are: Cirrus radiatus, Cirrostratus fibratus, Cirrocumulus undulatus, Cumulonimbus mammatus, Cumulonimbus incus, Altocumulus stratiformis, Altostratus translucidus, Altocumulus undulatus, Altocumulus castellanus, Altocumulus lenticularis
, Stratocumulus undulatus, Stratus opacus, Cumulus humilis, Cumulus congestus and Cumulonimbus with tornado (see information sheet that follows this release).
Divided into sections devoted to low, middle, and high clouds, this field guide to the skies includes such details as the ferocious, storm-producing capabilities of the cumulonimbus, the UFO-like appearance of the altocumulus lenticularis
, and the halo-forming tendencies of the cirrostratus.
