Options

• topo_wind = 1: Topographic correction for surface winds to represent extra drag from sub-grid topography and enhanced flow at hill tops (Jimenez and Dudhia, JAMC 2012). Works with PBL only.
• topo_wind= 2 a simpler terrain variance-related correction.
• ysu_topdown_pblmix = 1 option for top-down mixing driven by radiative cooling.
