applying nudging to the results in a sub region?

[turuncu]

Hi,

I am using nudging (only T and S) in my application using following CPP flags.

Code: Select all

#define TCLM_NUDGING
#define TCLIMATOLOGY

but in my case i want to apply nudging to only a specific sub-region (or i want to exclude a sub-region from nudging). Does it make sense in the ocean modelling point of view? If yes, which part of the code must be modified? I am using ROMS version 3.5 and ice version but i think nudging is not related with the ice model.

Regards,

Yes, you can do this and we do in the latest NEP6. In ana_nudgcoef.h, set up the nudging coefficients to describe what you want to do.

Note that the trunk ROMS will use the nudging coefficients set in that file for the open boundary condition nudging coefficients. That's not what I want, so my code differs from the trunk there.
