"Part of the beauty of Kelvin-Helmholtz clouds is... how, like waves in the ocean, the atmosphere moves and responds to the environment around it. The air is effectively rising up and tumbling over on itself."

Said the BBC weather man, quoted at "Kelvin-Helmholtz: Rare wave clouds amaze sky-watchers in Wyoming" (BBC).

Fantastic pic, thanks. It’s both fascinating and awe-inspiring to consider the physical forces and masses at work —at play?— in that little patch of sky. All over the planet, constantly, whether visible or not, acknowledged or not, admired or not, our atmosphere is being warmed by that big yellow ball blazing in interstellar space, even as it is being cooled toward the absolute zero that prevails in that interstellar space; and somehow, sometimes, in the endless turbulent flow of energized matter there is a quasi-stable state; an eddy in the current; an eddy that we call life; life that can pause from its preoccupations to look up and wonder.

This would actually indicate that many cartoons were in fact realistic and our notions of realism were wrong. The story also claims Van Gogh may have been inspired by these clouds...but that doesn't explain his swirly skies or trees or flowers so that's implausible IMO.

But, very cool clouds.

It's not environmental harmony but just the fastest-growing instability wavelength dominating across a wind shear.

Saw those last weekend while duck hunting in SW Idaho

Having seen a photo of the clouds, I wonder if Hokusai also saw them.

Are we playing "Jeopardy"?

Sheer poetry.

I saw this cloud formation once over Lake Michigan and could never find the explanation. Great to know. It was amazing to watch - fast-moving.

Nice. Not aware of such before. Thank you

Cap clouds are another fascinating beauty to behold, illustrating thermo- and fluid-dynamics.

Such waves aren't really that rare. I see pictures of them multiple times per year.
