Impacts of the low-level jet's negative wind shear on the wind turbine [PDF]
Wind Energy Science, 2017 Nocturnal low-level jets (LLJs) are defined as relative maxima in the vertical profile of the horizontal wind speed at the top of the stable boundary layer. Such peaks constitute major power resources for wind turbines.
