The simulated NIKE is too strong.

[tao]

I used ROMS to simulate the data of the South China Sea. In the figure, I selected the NIKE data from several stations and compared it with the Hycom data. It can be observed that both in the surface layer and the bottom layer, my data is overly strong compared to the actual situation. Could you please advise me on how to modify it? Which parameters or header file options are related to this? My English is not very good, so I used a translation software for the translation. I apologize if it has caused any confusion.
thanks for any suggestion
