Title: Elliptical cirrocumulus
Post by: colareis on May 18, 2017, 12:09:45 PM

Hello!
I live in Sevilla, Spain, and I was photographing the sunset at 9th May when these curved cirrus trees appeared in the sky. What type of cloud are they? Vertebratus, undulatus...
Could this cirrus be gravity waves?
Regards,
Nico.

Nico,
I was just reviewing my time lapse from last night's sunset and saw some Mare's Tails floating by at the end.... 

Thought I'd share....

Thanks a lot.
Nice time lapse Gregj.

That are the cirrus at the moment of the picture. The jet strean is located above that cirrus, to the north. Do you think that transverse band cirrus can be gravity-shear waves?
