Wave clouds being stationary in the wind, while the Glory cloud travels out from the desert to the northern ocean at a good clip (100 km/h?) It's a thousand kms out to sea, radiating out of a cold front. Only one kind of waves out there and they're not made of cloud. http://imgur.com/a/4Lspd shows the sat pic.

Still a fantastic cloud pattern, though. Why? The texture of the clouds says "(near) zero shear" to my eye and there darned sure isn't any proximate terrain. So I'd bet a beer on travelling waves. best, Evan

Changed my mind: took another look at the airliner pic - clouds are rotors rather than lenticulars. yellowplaintain's post mentions a cold front which rather clinched the roll cloud interpretation. -- martin@ | Martin Gregorie gregorie. | Essex, UK org |
