Short summary
Wind turbines interact with the atmosphere and affect the performance of nearby turbines. Using a large dataset from a wind farm in northern Germany, we studied how inflow conditions shape the flow behind a turbine, called a wake. Higher turbulence reduces the wake's length and impact, while stable conditions make it stronger. Wind direction changes with height can shift and skew the wake’s position. These findings help improve turbine wake models by considering varying atmospheric conditions.
