The turbine research I read about most recently
Wind farms: A danger to ultra-light aircraft? - Research News August 2012 - Topic 4
and there's a poster about it here:

If anything, they seem to suggest that wind gradient is a bigger problem than turbulence.
I agree, having now read the poster, that it's hardly the last word on the matter. I also hadn't realised anyone had gone so far as putting turbines on the airfield.
