This is just cool. And it is aviation related because I certainly wouldn’t
want to fly in it.

Sailplane pilots fly in wave lift all the time. You just have to
watch out for the rotor.

Glider pilots purposedly enter the rotor all the time, because this is
the staircase to the wave. Just stay below vB and be sure your straps
are tight.
That said, the wave in the picture was created by an inversion and not
by mountains. Inversion waves come without rotors. And a hint to power
pilots: If you understand wave and know how to use it, you can save a
lot of fuel.

Very different type of wave. The peaks, troughs, and nodes of the
wave you’re referring to are stationary – they are standing waves, and
are created by wind flowing over ridges or mountains. This "Undular
Bore Wave" is, as they state, a traveling wave.

Yup, on x-countries in California, you can slide over a couple miles and get in the slope lift and pick up 10-15
knots…
