To capture the wake downstream over complex terrain, we installed a scanning LiDAR at a real windfarm turbine in a mountainous site. The LiDAR successfully captured the spatio-temporal structures of multiple wake events. A significant wind reduction was observed up to 1.5D (D=rotor diameter) downstream of the turbine. Around 2D–2.5D leeward, the wind gradually strengthened, indicating a recovery in wind speed.
