A cloud in the lee of the Patagonian Andes observed during an entire day. The shape of the cloud changed from lenticular to whirl- and funnel-shaped.
Description by Christoph Mayr, after the description on imaggeo.egu.eu.
Konstantinos Kourtidis also added a comment to the image, explaining more about how lenticular clouds like these can form:
“That’s a great photo sequence. The cloud is a lenticular cloud, they are not often easy to see. When stable moist air flows over a large eddy, like those caused by a mountain, a series of standing waves form on the leeward side of the mountain. If the temperature at the crest of the wave drops below the dew point moisture condensation, it may form a lenticular cloud.”
