Wall Clouds Next Topic: Altocumulus Clouds

A wall cloud forms underneath the base of a cumulonimbus cloud, and can be a hotbed for deadly tornadoes.

Wall clouds are formed by air flowing into the cumulonimbus clouds, which can result in the wall cloud descending from the base of the cumulonimbus cloud, or rising fractus clouds which join to the base of the storm cloud as the wall cloud takes shape.

Wall clouds can be very large, and in the Northern Hemisphere they generally form at the southern edge of cumulonimbus clouds.

Next Topic: Cirrocumulus Clouds

Altostratus clouds form at mid to high-level altitudes (between 2 and 7 km) and are created by a warm, stable air mass which causes water vapor to condense as it rise through the atmosphere. Usually altostratus clouds are featureless sheets characterized by a uniform color.

In some cases, wind punching through the cloud formation may give it a waved appearance, called altostratus undulatus. Altostratus clouds are commonly seen with other cloud formations accompanying them.
