Ocean Modeling Discussion

Very helpful! Thank you very much, Kate!

One last approach is to nudge your TS fields to a climatology. You can set a variable nudging time scale along the vertical to impose stronger coefficients below a certain depth. This can be easily achieved by creating the variables temp_NudgeCoef(s_rho, eta_rho, xi_rho) and salt_NudgeCoef(s_rho ...

I got the following run error message using ROMS rev 748:

Thanks, osua72!

osua72,

(1) Where do you define the variable 'Hcount'? In the main input file?
(2) When you compiled, did you turn the 'wet_dry' on?
Thanks!

Another issue for help:

I got the following error message:
DEF_VAR - unable to define variable: Hcount
in NetCDF file ./my_harmonic.nc

What's the issue here? What's the Hcount?

I've tried that and still it showed the same error messages. I'll use the non-'wet-dry'. It should serve my purpose well. Thanks!

In Hernan's post,Cw occasionally appears to be rather large (i.e., > 1.0), while Cu/Cu are in the normal range. Would the large Cw cause any stability issue?

Thanks, Kate!

I tested and the ROMS code passed compilation only with
#undef WET_DRY
# define AVERAGES_DETIDE
# define AVERAGE

With "define WET_DRY", it gives error messages like
set_avg.f90(2330): error #6837: The leftmost part-ref in a data-ref can not be a function reference. [GRID]
& GRID ...

I have a cpp.h working working well (tested with a recent version of ROMS codes) for tide only run with following options.

#define SSH_TIDES /* flag - impose tidal elevation */
#define UV_TIDES /* flag - tidal currents */
#undef RAMP_TIDES /* ramp OBC data or the body forcing */
#define ADD_FSOBC ...
