generally form about 6,500 feet to 20,000 feet (2,000 to 6,100 metres) above ground level, a similar level to altostratus formations.
clouds can be banded or rounded in formation.
Leave the newspaper on the walk, the daily crapshoot-- a patch of sky still vague where Larry and all the others left on the threads of altocumulus

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.
is a puffy cloud at high altitude and cumulonimbus is a cumulus cloud that rains.
