Altocumulus volutus is a four-leaf clover in the sky

[Štěpán Šubík]

As we wrote about Altocumulus and its species, the rarest is Altocumulus volutus. It is very lucky to see this species above our heads.

Altocumulus volutus is quite like Stratocumulus volutus. That means a long, horizontal, detached, tube-shaped cloud mass which often appears to roll slowly about a horizontal axis. Unlike Stratocumulus, Altocumulus volutus is usually a single line and, like it is with the mid-level clouds, it appears smaller.

Photos of Altocumulus volutus are very rare even though it is a beautiful cloud that is not connected with precipitation. If you have seen one, send us your photos!
