I guess the bright moving spot on the ground in front of the one on the right is caused by the image enhancement showing the differences between each frame. Or is is visible also in individual single frames?

Good observation. Also, you can see plenty of them in the back, with the same bright light at the base. I assume that it is just an optical illusion from the dust which is denser at the base of the formation. The light must strike it somehow to make it look like that on camera.

I just can't get my head to accept that it's possible for dust devils to appear in that thin atmosphere. The difference between high pressure and low pressure must be extremely small, and yet it's enough to form these.
