Interesting hot air diffraction flow photo detail?

Looking through some shots I took of my buddy Steve flying our -8, and spotted an interesting visual display of the hot-air exit flow from the bottom of the cowl (and the exhausts).

Just something you don't usually see, and is down to light refracted differently through the varying temperature bits of air. I think the background helps make it obvious in this shot.

I don't think the exhaust has the density/mass to oppose the slipstream and generate significant turbulence.]

FWIW
 
Very cool picture!

I cannot tell what the exhaust is doing - the background changes at precisely the wrong spot.
 
Very neat. Very similar in nature to being able to "see" things you never imagined in a sound "image".
 
Cool, good eye. Minor correction: the light is being refracted rather than diffracted. Diffraction is something else.
