Weather Topic: What are Fractus Clouds?

Fractus Clouds Next Topic: Freezing Rain

A fractus cloud (scud) is a fragmented, tattered cloud which has likely been sheared off of another cloud. They are accessory clouds, meaning they develop from parent clouds, and are named in a way which describes the original cloud which contained them.

Fractus clouds which have originated from cumulus clouds are referred to as cumulus fractus, while fractus clouds which have originated from stratus clouds are referred to as stratus fractus. Under certain conditions a fractus cloud might merge with another cloud, or develop into a cumulus cloud, but usually a fractus cloud seen by itself will dissipate rapidly.

They are often observed on the leading and trailing edges of storm clouds, and are a display of wind activity.

Weather Topic: What is Graupel?

Home - Education - Precipitation - Graupel

Graupel Next Topic: Hail

Graupel is a form of precipitation that is created by atmospheric conditions which cause supercooled water droplets to contact snow crystals and freeze to their surface.

Sometimes known as soft hail or snow pellets, graupel is delicate and easily destroyed by touch. Whereas hail usually falls during severe weather, graupel doesn't require such conditions to form, and can form in mild precipitation similar to situations which produce snowfall.
