Using WRF LES in EMS

All other topics about postprocessing model data (GrADS and other software), about other numerical weather prediction software (including WRF-NMM and WRF-ARW discussion unrelated to UEMS/WRF EMS), and general meteorology talk go in this forum.

Using WRF LES in EMS

Post by marywrf » Thu Feb 20, 2020 4:06 pm

Hello fellow WRF People,

Does anyone have instructions on how to run WRF LES using EMS?

I found these instructions for running it in normal WRF but I'm struggling to convert them to EMS: http://home.chpc.utah.edu/~u0198116/wrf ... LES-1.pptx

I also found this blurb inside a conf file:
If you choose to turn the PBL scheme OFF (LES) then make sure to set the following below:
#
# a. sf_surface_physics (pick a nice non-zero option)
# b. sf_sfclay_physics = 1 (automatically set if bl_pbl_physics = 0 in domain list)
# c. Either:
# sfflx = 1 (Recommended - drag and heat flux from physics - see below)
# or
# sfflx = 2 (Drag and heat flux from tke_drag_coefficient and tke_heat_flux)
# d. diff_opt = 2 (Recommended - in run_dynamics.conf)
# e. km_opt = 2 or 3 (Recommended - in run_dynamics.conf)
# f. mix_isotropic = 1 (Automatically set)
# g. diff_6th_opt = 2 (Recommended - in run_dynamics.conf)
# h. Make sure other physics schemes are appropriate

More instruction is appreciated. Thanks!
