Summary Author: John Kupersmith
These saucer-like lenticular clouds over Mono Lake, California, were part of a Sierra Wave formation, caused by strong westerly winds coming over the Sierra Nevada range (off camera to right). They were triggered by the passage of a northwest-southeast moving cold front that rapidly increased the flow of air above the crests of the southern Sierra's. This type of flow often results in eye-catching altocumulus lenticularis clouds to the lee of the crests. Photo taken on November 7, 2013.
