A large eddy simulation in SOWFA [1] is used for validation of wind direction and wake displacement. Wake displacement at 6 diameters downwind is used to compare 150 simulations in DStoDyn. The SOWFA data remains within 2 standard deviations but still has un-modeled dynamics. • Wind Direction • ARMA model fitted to SOWFA • Yaw Misalignment • Exogenous input fitted to [2] • Crosswind Velocity • Combined ARMAX model • = 1, = 9, = 1 • Wake Displacement • Linear transform of cross-wind velocity
