Large eddy simulation study of the humidity variation in the shadow of a large wind farm
Wind Energy, 2020 Numerous studies have shown that wind turbine wakes within a large wind farm bring about changes to both the dynamics and thermodynamics of the atmospheric boundary layers (ABL). Previously, we investigated the relative humidity budget within a wind farm
