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.
