mammatus
Udder-shaped cloud formations
Mammatus describes a cloud formation with distinctive rounded, pouch-like bulges hanging from the underside of a cloud layer, resembling udders or bubbles.
These formations typically appear on the underside of storm clouds and signal atmospheric instability: The mammatus clouds warned of severe weather approaching.
The term comes from the Latin word for breast.
