- n. A cloud formation similar to cirro-stratus, but heavier and at a lower level; a stratus cloud at an intermediate altitude of 2 or 3 miles.
from The Century Dictionary and Cyclopedia
- n. A thin horizontal sheet of clouds, usually disappearing slowly: apparently a lower layer of what under favorable circumstances might have been a cumulus cloud. The outer surface, melting away at sunset, gives rise to beautiful sunset cloud-colors by reflection of light from the sun or the sky beyond the western horizon.
- n. A rather high cloud covering the sky as a layer whose lower surface is horizontal. The extreme boundaries of such an alto-stratus cloud thin away into a series of alto-cumuli.

Above 6,500 feet can be found altocumulus ("clumps or rolls") and altostratus (a "drab and featureless" haze), as well as the storm clouds nimbostratus ("dim, miserable") and cumulonimbus ("the shape of a blacksmith's anvil").
On this day, however, the sky, layered with thin altostratus clouds and smog, appeared to reflect human suffering and failed to awaken in Claude visions of paradise.

High-altitude cirrus, cirrostratus and middle-altitude altostratus clouds are found well in advance of the front.
Along the gently sloping warm front, the lifting of moist air produces first nimbostratus clouds followed by altostratus and cirrostratus.
It was a good blue one, with a few puffy cirrocumulus clouds, and some altostratus thrown in for contrast.
With the thicker altostratus and nimbostratus clouds comes the rain, which is then followed by clear and warmer weather.
There was only one cloud to be seen, but it covered the entire soggy Irish sky, dropping rain all day - a "drizzling altostratus", since you ask.
According to meteorologists, there will be a layer of scattered stratocumulus clouds between 2,500 feet and 5,000 feet, scattered altostratus clouds between 10,000 feet and 12,000 feet, and scattered cirrus clouds between 28,000 feet and 34,000 feet.
We would call out, cirrus, cumulus, stratus, altostratus and cumulonimbus from the back seat.
