For a morning, the sky looked like a surfer's dream: A series of huge breaking waves lined the horizon in Birmingham, Ala., on Friday (Dec. 16), their crests surging forward in slow motion. Amazed Alabamans took photos of the clouds and sent them to their local weather station, wondering, "What are these tsunamis in the sky?"

Experts say the clouds were pristine examples of "Kelvin-Helmholtz waves." Whether seen in the sky or in the ocean, this type of turbulence always forms when a fast-moving layer of fluid slides on top of a slower, thicker layer, dragging its surface.

Water waves, for example, form when the layer of fluid above them (i.e., the air) is moving faster than the layer of fluid below (i.e., the water). When the difference between the wind and water speed increases to a certain point, the waves "break" — their crests lurch forward — and they take on the telltale Kelvin-Helmholtz shape.

Nifty. Is there an associated storm?

That's what a ship is, you know - it's not just a keel and a hull and a deck and sails, that's what a ship needs.

Crap, the pics aren't showing up now, but the link still works. No, don't think there was any crazy storm, just curious weather. Stuff like this happens, but it's rare.
