The earth is pretty awesome. And because it is Earth Day, I am going to celebrate one of my favorite Earth features: internal waves.
I mean look at this awesome sequence of 3 internal waves groups you can see from space. These solitons are coming at you Palawan, breaking in UR seashores.

Solitons are a particular type of internal wave that become humongous through a series of complicated interactions. But all the action is underwater. The surface wave while incredibly wide, is less than a meter high!

Here are some smaller, yet equally impressive internal waves from my neck of the woods: Bellingham Bay, Washington. Seriously lens dust, you are blocking some truly awesome internal wave imagery.

Look at this internal wave refract and wrap its crests and troughs around Dongsha Island in the South China Sea. It’s like ocean physics is giving geology a hug. AWWWWW.

YOU GUYS. This is buy-one-get-one-free of internal waves.

Speaking of the atmosphere, did you know there are internal waves in the sky too? OH HAI baja, make me some waves.

Winds blowing past a cluster of South Sandwich islands makes a cluster of waves. But the real question is will they make a wave sandwich?

Let’s just make cram my love of ocean, waves and ice all into one image. Atmospheric internal waves created by icebergs. I’m just going to go explode now. HAPPY EARTH DAY!

Those are beautiful phenomena. Can you explain more about that “surface wave under a meter high” thing? The “internal” wave action is between density strata of the water, if I understand what we’re talking about. (?) What’s the effect they have on the air/water interface, to displace it vertically like that?
