Hi, everyone,
I have run the Roms nearshore with horizontal resolution is 500 m.
In model, we only give the tidal foring and the river foring.
we use the k-kl (turbulence closure parameters) of GLS.
After the model is stable, I find the surface salinity of the modeling region is smaller than that in observation.
even if we rise the salinty of river from 0 to 20, the runoff quantity is the real observation, the it doesn't help the increase in salinity.
we find one of point, compare the result of surface salinty in modeling and observation:
Also, we have test the .bry file, the salinty in east boundry is about the 31,while the salinty in the modeling of the east boundry is about 25~26 in the same time.
Thanks in advance for any help,
Zhixing Chen

Re: The salinity is too small
Have you tried adding salinity correction term to the CPPDEFS key ?

Re: The salinity is too small
Thanks for your reply, whether you mean is turning on the ‘QCORRECTION’ and ‘SCORRECTION’ these two switches in the .h file?MIDHILAVARNAV wrote: ↑Tue May 09, 2023 5:40 am Have you tried adding salinity correction term to the CPPDEFS key ?

Re: The salinity is too small
Yes, adding the same in the header file and recompiling it.

Re: The salinity is too small
I gave it a try, and find that these two switches need the .frc file, however I don't have such a forcing file.MIDHILAVARNAV wrote: ↑Tue May 09, 2023 8:50 am Yes, adding the same in the header file and recompiling it.

Re: The salinity is too small
The forcing file which is required is climatological (roms_frc_woa365.nc), which could be created easily using the Romstools toolbox (specifically for your grid) using
climatological World Ocean Atlas data (WOA2013).
climatological World Ocean Atlas data (WOA2013).
