[MITgcm-support] Inertial Oscillations

[Stroman, Ashley]

Hi Dustin.

That is something I haven’t considered, but I can certainly check that out.

However, I’m more familiar with prescribing constant velocities at every time step, and not velocities that are dependent upon time and Coriolis in a more precise manner by way of inertial oscillations.  So I guess to be more specific in my original question, I’m not sure if I will need to modify the obcs_calc.F file, or if I can somehow use the “prescribe” option within pkg/obcs to set the boundary conditions for velocity which are dependent upon both time and coriolis.  I know that there is a time forcing component, but I’m just not sure how everything fits together.
