M2FLATHER and M2CLM_NUDGIN

#1 Unread post by staalstrom »

Hei

I'm working on an application on the western coast of Norway and I have problems with the open boundary conditions. ubar and vbar have too high values close to the border.
So I want to try nudging close to the boundary. I have made a nudging coefisient in ana_nudgcoef.h.

I use these option on the boundary (dont mind the misprint in the comments)

#define WEST_FSCHAPMAN /* Southern edge, free-surface, Chapman condition */
#define WEST_M2FLATHER /* Southern edge, 2D momentum, Flather condition */
#define WEST_TRADIATION /* Southern edge, tracers, radiation condition */
#define WEST_TNUDGING /* Southern edge, tracers, passive/active term */
#define WEST_M3RADIATION /* Southern edge, 3D momentum, radiation condition */
#define WEST_M3NUDGING /* Southern edge, 3D momentum, passive/active term */

I also have these

#define TCLIMATOLOGY /* Processing of tracer climatology */
#define TCLM_NUDGING /* Nudging of tracer climatology */
#define M3CLIMATOLOGY /* Processing of 3D momentum climatology */
#define M3CLM_NUDGING /* Nudging of 3D momentum climatology */

I think that this results in nudging for only the baroclinic vaiables.
So my question is. Is it possible to use WEST_FSCHAPMAN and ZCLM_NUDGING at the same time?
And WEST_M2FLATHER and M2CLM_NUDGING at the same time?

best regards
