[MITgcm-support] unrealistic model results in a regional model

[Fanglou Liao]

Dear MITgcm support

I am a new MITgcm user. I am building a regional ocean model with mitgcm, and have some problems with the model results, which I guess are associated with the open boundaries (East and South).  This model is of 0.03 deg, with initial (T, S, U, V) and open boundary conditions are interpolated from CMEMS reanalysis (0.083 deg). The external forcing are from ERA5. The Δt = 45 seconds. The model results are unrealistic, with small-scale patterns appear (attached), and the SST even dropped below 0 after a few days. When I closed the east and south boundaries, these problems disappeard.  Could you please kindly help me check my files attached and give me some advices?

Thank you very much
