It’s astonished me, from time to time, how gases act like fluids, and rock acts like a fluid, and everything, basically, acts like a fluid if you look at it the right way.
Here is a post that shows some really stunning cloud formations that I don’t think I’ve ever seen in real life. They are called Kelvin-Helmholtz clouds, and if I heard about this kind of cloud formation when I took Earth Science, I don’t remember it. I would remember, so I don’t think this was included in the chapter on the atmosphere and clouds and stuff.
They looks like waves breaking because – they’re waves, breaking. Much the same fluid dynamics equations are at work as in our seas, giving a slightly unsettling reminder than we all live at the bottom of an ‘ocean’, except it’s made of air, not water. …
If I ever see this now, I’ll certainly notice — and I’ll understand the clouds look just like breaking waves because the air is acting like a fluid. Or mayby the air actually is a fluid, I guess, if you define terms the right way.
