Abnoraml high/low temperature along the coast?

[rongzr]

Hi,All,I'm running a ROMS case in the Yellow Sea, China, with tides switched on. I got abnormal high temperature along the coast in summer, and abnormal low temperature near the front. The attached figure is the surface temperature in August. It seems to me that the tidal front is too strong. How to deal with it. Which parameters should I play with? Thanks.
