Lone Pine Lenticular
April 24, 2007
The photo above shows a portion of a "Sierra wave" or lenticular cloud darkening the winter landscape of the Alabama Hills, near Lone Pine, California. This cloud, technically an orographic stratiform cloud, formed when moist but stable air was uplifted over the Sierra Nevada range. Though ominous in appearance, the weather beneath this impressive lenticular cloud was rather benign-- wave clouds typically aren't associated with damaging winds or precipitation events. Photo taken around 8:30 a.m. (local time) on Christmas Day.
