Cirrus duplicatus is a variety of
cirrus cloud. The name cirrus duplicatus is derived from
Latin, meaning "double".[2] The duplicatus variety of cirrus clouds occurs when there are at least two layers of cirrus clouds. Most of the time, occurrences of
cirrus fibratus and
cirrus uncinus are in the duplicatus form.[3] Like
stratus clouds, cirrus clouds are often seen in the duplicatus form.[4]
