Cirrus intortus is a variety of cirrus cloud. The name cirrus intortus is derived from Latin, meaning "twisted, wound".[2] The variety of intortus clouds is specific to cirrus clouds, and they appear as interwound strands of cirrus clouds with a purely random pattern.[3] The filaments are often curved in a very irregular pattern.[4]

Like other cirrus clouds, cirrus intortus occur at high altitudes.[5]
