Re: Large Initial Current caused by temperature mixing in shallow water regions?
Final Update I think all the trouble is because of the LP-Smoothing method that I used, although it preserved the overall features and the smothed my Rx0 and Rx1 correctly , I forgot to take in to account for the difference bewteen my finished bathy vs the bathy of the Hycom model and did some bad ...

Re: Large Initial Current caused by temperature mixing in shallow water regions?
Update again , after doing some reading I realized that this is due to the initial temp and salinity fields that I inputted, the actual HPGE test requires a initially stable analytic T,S field. So this is purely due to the density gradient and can be called the upwelling currents? it causes some ...

Re: Large Initial Current caused by temperature mixing in shallow water regions?
Update ... I tried the "HPGE" test by setting all forcing except temp and Pair to zero, defining TS_FIXED , letting initial zeta, u ,v be 0 and found out the current will still happen, this is the velocity after a few minutes.. Does that mean this is purely due to my grid being not smooth and I ...

Large Initial Current caused by temperature mixing in shallow water regions?
I am an ocean modelling amatur and doesnt have much knowledge in running ocean models. I am running ROMS model on a 10km resolution domain with a 10 sec timestep I observed that my free surface behaves weirdly like this at about 2 minutes and couldn't figure out why https://i.imgur.com/8zJwPaR.png ...

Available non-Matlab based Bathymetry smoothing schemes
Hello, I am a new user to COAWST and subsequently ROMS. I am using GEBCO as the 'base' of my grid's bathymetry, and I am having trouble reducing my rx1 in steep regions of my model domain. I am convinced that its the main issue affecting my simulation as my vertical Courant number exceeds 1 when its ...
