Hi,
I want to analyze the water vapor(qv) budget by WRF. I have already found the PBL, cumulus, microphysical tendencies of qv, e.g., RQVBLTEN, RQVCUTEN, but the most difficult problem is the horizontal/vertical advection tendency of qv. Has anyone output it?

Any help will be appreciated.
 
The moisture diffusion term is computed in dyn_em/module_diffusion_em.F (look at the subrountine vertical_diffusion_s and horizontal_diffusion_s);

The moisture advection is computed in dyn_em/module_em.F (see subroutine rk_scalar_tend, in which the term advect_tend is for advection).

Please follow the instruction here (http://www2.mmm.ucar.edu/wrf/users/tutorial/201907/gill_registry.pdf) to output these tendency terms.

Thanks! I will look into these codes.
