[MITgcm-support] oscillating mean flow

[Klymak Jody]

Hi Mark,

I forget how the verification example works, but I typically just  
sponge U at the boundaries and have a mode-1 obcs.  The pressure  
gradient sets itself up.  I haven't tried adding a mean on top of an  
oscillation, but I can't think of any reason that wouldn't work fine.   
The only trick I've had to do is make sure the barotropic lag from one  
end of my domain to the other is accounted for or you get a partial  
standing wave.

Let me know if you'd like some code.

Cheers,   Jody
