Hole Punch Clouds Next Topic: Mammatus Clouds

A hole punch cloud is an unusual occurrence when a disk-shaped hole appears in a cirrostratus, cirrocumulus, or altocumulus cloud.

When part of the cloud forms ice crystals, water droplets in the surrounding area of the cloud evaporate. The effect of this process produces a large elliptical gap in the cloud. The hole punch cloud formation is rare, but it is not specific to any geographic area.

Other names which have been used to describe this phenomena include fallstreak hole, skypunch, and cloud hole.

Nimbostratus Clouds Next Topic: Precipitation

A nimbostratus cloud is similar to a stratus cloud in its formless, smooth appearance. However, a nimbostratus cloud is darker than a stratus cloud, because it is thicker.

Unlike a stratus cloud, a nimbostratus cloud typically brings with it the threat of moderate to heavy precipitation. In some cases, the precipitation may evaporate before reaching the ground, a phenomenon known as virga.
