[MITgcm-support] tidal forcing and wind forcing

[Menemenlis, Dimitris (329D)]

Dear Himansu, if you are studying a regional tidal problem, the lateral tidal
boundary conditions cannot (usually) be neglected.

For external tides, the lateral forcing is constant at every depth, so you don't need to provide
a different velocity forcing at every level.

There is code available where you only specify tidal amplitude and phase at each boundary
point for each tidal component that you want to consider.

Examples are here:

Regards, Dimitris

@ Dimitris : I have provided tidal forcing in code/external_Forcing.F as it was a bit easier comapred to its counterpart (using open bounday horizontal velocity (OPHV) forcings). In OPHV forcing, velocity at all the vertical levels are unknown to me in an open ocean and also large number of files are to be made for 30-50 days simulation. I have never tried to force the model with "surface atmospheric pressure".
