[MITgcm-support] 回复： Open boundary problem!

[Ertyy]

Here is the setup of the data.obcs, Model grid is 300*180(nx*ny), and I thought that the CPP options for OBCS have been configured properly.
# ***************
# Open boundaries
# ***************
 &OBCS_PARM01
  OB_Jnorth = 300*180,
  OB_Iwest  = 180*1,
  OB_Ieast =  180*300,

Dear MITgcm users:
      I have configured an application for regioanl ocean circulation simulation based on the MITgcm, and got the lateral boundary data from SOAD reanalysis. 
     The prescribed open boundary conditions were turned on (u, v, S, T were prescribed), and the model can read in these data and put it on the right position.However, it seems that the interior can not feel the prescribed boundary value, especially for the velocity field, strong reflection happened at the bounday. 
     I have no idea what happens, and where the problem comes from, is anyone have experience with this?
