offshoreward jet

#1 Unread post by guyz »

we dected the dramaticlly offshore transport of cold water off Guangdong coast, but I failed to reproduce this phenomenon. Attached are MODIS SST and my model result. Any suggestions are greatly appreciated
following is my .h file:

This is largely a wind-driven event, right? What are you using to provide the surface stress to the model? BULK_FLUX? Stresses computed elsewhere? At what temporal and horizontal resolutions?
