One question about Tidal Forcing

#1 Unread post by wangzhy »

To whom it may concern:
I run a northwest pacific model with tidal forcing, but I find some errors in the tidal constitents(e.g. K1, M2). The phases of M2 have many rags in the deep-ocean area, as showed in the Figure:
M2  _n.jpg

The phases of K1 have the same problem to M2 tidal constitent, as showed in the Figure:
K1  _n.jpg
K1 _n.jpg (78.78 KiB) Viewed 2554 times
I use the following cpp to add tidal forcing:
#define SSH_TIDES
#define RAMP_TIDES
#define UV_TIDES
#define ANA_FSOBC
#define ANA M2OBC

The south boundary condiation as:
#define SOUTH_FSCHAPMEN
#define SOUTH_M2FLATHER
#define SOUTH_M3RADIATION
#define SOUTH_TRADIATION
Others boundarys are same as the south boundary.

Who can tell me how to solve the problem? I would appreciate your help.

Was these figures illustrating your model results or just the forcing?

Did you also include the other forcings? wind, river, or remote forcing from the major currents? Kuroshio, NEC etc...

what is your horizontal mixing algorithm? harmonic or biharmonic, what is the coefficient?

I didn't include the other forcing. The surface boundary condation used ANA_SMFLUX and ANA_STFLUX without wind, but used river which don't I think can influence the tidal.
The horizontal mixing algorithm is UV_VIS2. The coefficient is VISC2=20.0d0
