It also looks like you have specified some inconsistent lateral boundary conditions, especially at western boundary. I suggest you examine the lateral boundaries in more detail in the model output —they should be included in model output.  Also, animations of 2D quantities and comparisons with global fields from which you extracted the open boundaries are often quite useful in diagnosing problem.

 Hi Pragnya,

looks like numerilcal instabilities due to insufficient viscosity. Please share your namelist files, grid spacing, etc.

Hi,
I am new to MITgcm and I am running the model forcing with
climatological wind, and proving climatology open boundary boundary condition t,s,u,v. But after 8th day onwards a formation of horizontal strips in currents can be observed (the image is attached). Kindly, suggest how do I solve this issue.
