Ocean Modeling Discussion

Hi, everyone I'm using COAWST as my coupled model by activating the ROMS and WRF models. To save the calculation cost, I wish to run a two-domain WRF and one-domain ROMS. The parent domain of WRF has the same grid as ROMS. If I don't have a two-way nested domain in the WRF, I actually do not need to...

Thank you for your quick reply. I tried the option LMD_SHAPIRO. It still happened （figure attached). Could it be related to my horizontal vis/diff coef? For now, they are： DT=60 NDTFAST=30 . . . TNU2 == 30.0d0 (I tried 25, 5, 1 also) VISC2 == 300.0d0 (I tried 100, 25, 5) My dx=dy=21km. I also tried ...

Dear all, I'm facing a strange unrealistic discontinuity of surface salinity in my COAWST (only ROMS activated) attached below. At the northern part, I found the freshwater flux was likely input at every other grid. Actually, after the rain stops, the salinity was reasonably diffused by horizontal d...
