Lenticular clouds, Altocumulus lenticularis, are stationary lens-shaped clouds that form at high altitudes, normally aligned perpendicular to the wind direction. Lenticular clouds can be separated into altocumulus standing lenticularis (ACSL), stratocumulus standing lenticular (SCSL), and cirrocumulus standing lenticular (CCSL). Due to their shape, they have been offered as an explanation for some Unidentified Flying Object (UFO) sightings. (source: Wikipedia)
Okay, thanks to my friend Norman Ávila from ClimaYa.com I’ve learned the proper name for this kind of cloud formation. A lenticular cloud was first shown here on the entry The War of the Worlds, a contribution of my friend Pascu Robredo. Check out it, I’m sure you’ll enjoy the parody of Orson Welles radio show.
