Claim 0:
1. A method for controlling wind turbines of a wind farm comprising a plurality of wind turbines, the wind farm being positioned at a site which includes one or more turbulence generating structures, the method comprising:
detecting a wind direction at the site of the wind farm;
identifying one or more upstream wind turbines and one or more downstream wind turbines, based on the detected wind direction, where each of the upstream wind turbines is arranged in front of one or more of the downstream wind turbines, as seen in the wind direction;
detecting that turbulent wind conditions are occurring, based on measurements performed by the wind turbines of the wind farm, and wherein detecting that turbulent wind conditions are occurring comprises:
measuring wind speed by one of the one or more upstream wind turbines and by one of the one or more downstream wind turbines; and
determining that turbulent wind conditions are occurring if the wind speed measured by the one of the one or more downstream wind turbines exceeds the wind speed measured by the one of the one or more upstream wind turbines by a predefined wind speed difference; and

controlling at least one of the upstream wind turbines based on measurements performed by at least one wind turbine which is a downstream wind turbine relative to the upstream wind turbine.
