Hello,everyone.
I tried another initial condition derived from hycom, and used nudging mentioned above (20 days of nudging time scale for outflow , 0.5 day for inflow).It partly works(I don't know which contributes more to this, intialization or nudging),however not good enough.
ssh and barotropic velocity
http://photo.blog.sina.com.cn/u/1190472905The title plus 90 is the day number of my simulation.(ie. 45+90=135 which means this is the 135 day's simulation.)Click the photo to see more clearly.
The kuroshio doesn't show up clearly, the surface elevation doesn't look good with too much strong holes(low ssh).So the velocity field is quite a mess.I also think Kuroshio water intrusion through luzon strait is too strong,and the Kuroshio(if is can be called Kuroshio) is too northward.
I wonder is there any model configuration I can do to change this simulation better?
