A spectacular example of Altocumulus lenticularis duplicatus in Iceland. There are multiple stacked lens or almond shaped patches, increasing in size with height. The mountain waves responsible for this cloud are also reflected in the extensive layer of undulating Altostratus above the lenticularis clouds. Photo: Gréta S. Guðjónsdóttir/WMO.
