Numerical model simulations of idealized and observed flows are used to investigate the dynamics of low-level jet streams that form in stratified flow downstream of the vertex of large elliptical barriers such as the southern tip of Greenland, hereafter referred to as ‘‘tip jets’’. The tip jet dynamics are governed by conservation of Bernouli function as parcels accelerate down the pressure gra...

Low-level jets (LLJs) are the wind maxima in lowest 50 to 1000 m of atmospheric boundary layers. Due their significant influence on power production farms, it is crucial understand interaction between LLJs and farms. In presence a LLJ, there positive negative shear regions velocity profile. The continuously turbulent, while have limited turbulence. We present large eddy simulations farms which ...
