[MITgcm-support] eddy transported by mean flow barotropic gyre

[Peng Zhan]

Hi Yang,
I suppose that you added the eddy by adjusting the wind stress would only
affect the surface/ near-surface current, for which the EKE is not high
enough for propagation. Have you checked how deep is your strong small eddy?
