Lenticular cloud. This cloud type,also known as altocumulus lenticularis,gets its name from its smooth lens-like shape. These clouds are produced when moist air ascends over a mountain,and air waves form on the lee side of the mountain. As the wind rises and moisture is present in the air lenticular clouds rise up. If alternate layers of moist and dry air are present,the clouds form into a stack. These clouds are often mistaken for Unidentified Flying Objects (UFOs). Photographed off South Georgia Island | |
