Lenticular Clouds

by curiousmiscellany

Is it a bird? Is it a plane? Is it a UFO? No! It’s a lenticular cloud (or if you want to be nerdy about it: altocumulus lenticularis). These slow-moving, often stationary, lens-shaped clouds are most typically formed at high altitudes, near mountain ranges and hilly areas, where moist air creates a series of standing waves as it flows over the peaks to the downwind side. Lenticular clouds become even more dramatic when irisation (the formation of irridescent colors from the diffraction of sunlight by water droplets in clouds) occurs near their edges.

Beam me up.
