[MITgcm-support] Orlanski boundary condition

[Estanislao Gavilan Pascual-Ahuir]

Dear community,

I am no sure how it works this boundary condition. I mean in theory allows waves to leave the domain. Therefore, this can change the flow at the boundary. I have set a small experiment where I open a North and a South boundary.  I prescribe a flow across the south boundary and a set the north boundary with the Orlanski boundary condition. I would have guessed that this produces an outflow across the North boundary but I did not observe that. Do I need to active the useOBCSbalance? Thanks so much in advance fo your help

Kind regards,

Estanislao
