[MITgcm-support] the_changes_of_ocean_currents

[Matthew Mazloff]

Hello

Are you using OBCS?
Perhaps your prescribed open boundary conditions are inconsistent with the interior flow. A restoring (sponge) layer may help.

In the data file, I have added topography, temperature, salinity, wind stress, flow velocity, and used forced fields(EXF). Starting from the third hour of the simulation, the direction of the ocean current showed a significant deviation from the measured data. Could it be that I haven't added boundaries yet? I'm not quite sure where the problem lies. I sincerely ask for your guidance on possible problem points.
