[MITgcm-devel] changes in seaice with OBCS

[Jean-Michel Campin]

Hi Dimitris,

Thanks for doing this. I made the checkpoint62n tag yesterday.

I have an other question related to obcs_apply_seaice.F:
I would like to remove all the conditions on non-empty 
file-name when applying OBC to seaice fieds:
>           IF ( SEAICEadvHeff .AND. OBNhfile .NE. ' ' )
>     &          HEFF(I,J,bi,bj)  = OBNh (I,bi,bj)
>           IF ( SEAICEadvArea .AND. OBNafile .NE. ' ' )
>     &          AREA(I,J,bi,bj)  = OBNa (I,bi,bj)
In fact, I don't know how the seaice model will deal with OB 
when only part of the fields are specified in OB regions.
I expect some funny things when the ice-field is advected.
And in the case where the ice field is not advected, I really
don't know. I would be tempted to remove also the test
"IF ( SEAICEadvHeff )", and to always apply what has been 
set in obcs_calc, to make seaice-obcs like ptracer,T,S,
and momentum (all the other obcs_apply S/R).

But may be a more basic question, is this feature (not to 
apply OBC to some seaice-fields when it's done for other
fields) used and for what purpose ?
If this is really a feature we want to maintain, I am afraid
this might be broken after my recent changes.

Cheers,
Jean-Michel
