Lenticularis – a rare lens-shaped cloud formation

Lens shaped clouds

Lenticularis is a rare lens-shaped cloud formation that occurs as a result of moist air flow around mountains.  The name is obviously derived from its lens shape, which is not unlike the stylised figure of a flying saucer.

These clouds can occur at all levels (high, medium or low) but the most dramatic occur at the mid level (Altocumulus lenticularis) as in the accompanying photograph.

We encountered this cluster lenticularis in New Zealand in the mountains around Mt Cook, but saw them on a number of other occasions during  recent touring holiday in New Zealand.

Remember to keep your eye on the sky when out and about. Get a copy of the Cloud Collector’s Handbook and add this dimension to your travel (and everyday) experiences.
