Look at this Danish site: and plot wind speed after an obstacle. You will find that in most practical cases wind speed at ground level is unaffected after two miles (same as if there was no obstacle). I guess the extra turbulence created by the obstacle disappears as well provided that wind speed is unaffected within ten meters above the ground.
