In the atmospheric boundary layer, the Coriolis force associated with the Earth’s rotation induces a spanwise wind shear in addition to the wall-normal one leading to a continuous change in wind direction with height. The spanwise wind shear in directionally sheared inflow has a significant impact on the formation and development of wind-turbine wakes. The present work aims to provide an analytical framework for predicting wind turbine wakes in directionally varying wind shears.
