Modeling dynamic wind direction changes in large eddy simulations of wind farms

The wind direction in atmospheric boundary layers changes continuously due to meso-scale weather phenomena. Developing accurate simulations of these is essential for understanding their effect on the performance large farms. Our study introduces a new technique model dynamic obtained from or field measurements micro-scale eddy simulations. We propose method which simulation domain treated as non-inertial rotating reference frame. primary benefit our approach that it straightforward implement and reproduces desired excellently. verified neutral show observed boundary-layer characteristics directions agree very well with those constant mean when changed slowly such flow quasi-stationary. Further, we can be reproduced by method. To underline importance method, conclude representative scenario, shows affect
