Definition: wind velocity experienced at a fixed point of the rotating wind turbine rotor

NOTE – The turbulence spectrum of a rotationally sampled wind velocity is distinctly different from the normal turbulence spectrum. While rotating, the blade cuts through a wind flow, that varies in space. Therefore the resulting turbulence spectrum will contain sizeable amounts of variance at the frequency of rotation and harmonics of the same.
