Interesting Look at Wind Farm Influence of Localized WeatherNovember 28th, 2012 at 10:56 pm by Chad Evans under Chad's WLFI Weather Blog
Wind farm turbines can mix the air underneath & around them, dissipating fog quicker than the surrounding countryside or keeping from getting as dense as surrounding areas. This can be seen in recent dense fog satellite images here in late November. On November 21, this was especially seen. Check out the visible satellite images. The holes in the fog occurred where wind farms are located in central Illinois & western Indiana.
