Calculating the ustar and heat flux

Postby wrfsouri » Wed Jan 30, 2019 5:43 pm

Hi, guys,

I'd like to change the Cd scheme in wrf to calculate the air-sea momentum flux, the sensible heat flux and the latent flux.
The boundary layer and surface layer schemes are YSU(bl_pbl_physics=1) and MM5 Monin-Obukhov scheme (sf_sfclay_physics=1) respectively.
In the code of module_sf_sfclay.F, I found that the ust (ustar) have value before calling the subroutine SFCLAY1D.
Does someone know where the ustar is calculated firstly/primarily?
Thank you!
