cirro-
(meteorology) related to clouds of high étage
Examples
Stratocumuliform and stratiform clouds in the high étage carry the prefix cirro-, yielding the respective genus names cirrocumulus (Cc) and cirrostratus (Cs).
Stratocumuliform and stratiform genera have the prefix cirro- when they occur in the high étage, and alto- when based in the middle altitude range.
They are given the prefix "cirro-", but this refers more to their altitude range than their physical structure.
