Since it is only affecting five of the 126 wind farms in the UK, is aerodynamic modulation (which I take to mean ‘beats and resonance’) in this context caused/enhanced by topography (ie are the wind farms that exhibit aerodynamic modulation in, say, relatively flat areas?), and/or is it related to the relative positions of the turbines?
They seemed to have narrowed it down to a few poor designs. The guinea pigs just happen to be human. The business of global warming will move on...
More likely the blade design interacting with the pylon (support pole) shape and position.
