MPAS dycore support for moving mountains parameterization

[PeterHjortLauritzen]

What is the feature/what would you like to discuss?

The new moving mountains scheme in CAM7 requires the dycore to compute vorticity and pass it to physics.

Basically we need this call in mpas/dp_coupling.F90

 if (use_gw_movmtn_pbl ) then
         call gws_src_vort(elem, tl_f, tl_qdp_np0, vort4gw, nphys)
 end if

where gws_src_vort computes vorticity (subroutine located in gravity_waves_sources.F90).

Could the MPAS team provide this code so MPAS can me fully supported with CAM7? @kuanchihwang @gdicker1 @mgduda

Is there anyone in particular you want to be part of this conversation?

Will this change (regression test) answers?

Yes

Will you be implementing this enhancement yourself?

No
