Other Dynamics Options

There are various other dynamics options that can be set in the &dynamics section of namelist.input. The below list is not fully-inclusive and users should see the Namelist section for all options.

  • non-hydrostatic=.false. : allows WRF to run hydrostatically

  • pert_coriolis=.true. : an option for ideal simulations only that applies the Coriolis term to wind perturbation only.

  • mix_full_fields=.true. : only when setting “diff_opt=2” and only for ideal simulations, allows vertical diffusion to act on full fields (not just on perturbation from the 1D base profile

  • To obtain a more accurate moisture solution, use

    • use_q_diabatic=1 : includes the QV and QC moisture tendencies from microphysics in small steps. For real-data cases, the time step should be reduced to maintain a stable solution. See Bryan, 2014

    • use_theta_m=1: considers the moisture effect on pressure in small steps (theta_m=theta(1+1.61Qv). The current implementation may cost a bit more to run.
