It drifts along with the rest of the fog, and stays like that for a few hundred meters before the fog peters out. It ain't turbulence.

The rotors EXTRACT energy from the air, so the airflow behind the rotor should be slower than the rest of the free airflow.
Heres the background to those fog pictures: http://www.mdpi.com/1996-1073/10/3/317/pdf-vor

The wind were blowing 25 Knots above that fog.
