Skywatch Friday - Wave Clouds

This picture was taken from Sabino Canyon on Tuesday, January 20, 2009. Kelvin Helmholtz instability clouds form between two layers of air which have different densities and travel at different speeds. They are also called billow clouds or shear-gravity waves. Perhaps swirly clouds such as these inspired Vincent Van Gogh to paint his Starry Night.

What a unique cloud! It looks like a child's drawing of ocean waves. I agree, it really does have a 'Van Gogh inspiration' look!

Those clouds are really cool. I don't think I've ever seen any like that.
I lived in Tucson for many years and I am enjoying your Sabino Canyon photos. Do you ever post any of Madera Canyon too? Or Mt. Lemmon?

Diane said...

Hi Susie of Arabia - Thanks for your comment and question. I rarely leave home, so most of my photos are of the Sabino Canyon area.

Great shot, I bet that cloud was fun to watch in person, especially from up in the canyon. I hiked a many trip up Ventana Canyon in my days out there.

Gaelyn said...

Too cool! Like white-water waves in the sky. I've never seen this cloud formation, other than VanGogh.

Hey Diane, I was just at Sabino this morning. It was raining then. I guess your litle cloud grew up and invited all its kin!

I have heard about these clouds but never seen them. I love this photo and also the skywatch photo below with the grand wisps of radiant clouds. Beautiful.
