Ocean Modeling Discussion

Dear all, At first, the model could finish without an obc.nc (open boundary file about temperature and salt). But when I use the obc.nc about temp and salt ( the shape = [39 20 230/300] [temp_time, s_rho, xi_rho] ), the model would always blow up in the 208 days. The temp_time about obc.nc is in the...

If the graphic is showing the computational domain, with rho points going from 1 to Lm, 1 to Mm, then the outer edge is the location of the boundary. Thank you,Kate. When we set value for each boundary, how can we judge the boundary direction? According to the computatioal grid or the reality geogr...

2-D zeta_east = S.zeta(end,:); zeta_west = S.zeta(1, : ); zeta_north = S.zeta(:,end); zeta_south = S.zeta(:, 1); Thank you very much for your quick reply. Seems I have a misunderstanding in the direction distributions. I think all the matrix must be have directions like I showed in the former figur...

Dear all, I want to set value for boundaries. As my understanding, boundary direction should be like this(shown in the attached figure): The first row in the table (matrix) represents the north , the end row represents the south; the first column represents the west and the end column represents the...

Dear all, I have 2 questions about adjoint model running. Q1. I want to get the backward vars in 2008. So I run 2 years (2007-2008) forward simulation with the first year for spin-up. I only stored the forward station every 3 hours in 2008. Am I right to ignore the stations in 2007? Q2. I try to run...

Guys, it seems you are talking about two different things :D . John, perhaps wuting0926 wants to calculate the tide-induced Stokes drift, not the wave-induced Stokes drift. There are couple of ways to define the tide-induced Stokes drift, based on pure Lagrangian or Eulerian perspectives. As Wuting...

Dear jcwarner,
Thanks again for your warmly guidance, you really give me much help. My focus is on the Lagrange residue current to see the mass transport instead of the wave-current interaction. So I prefer to adopt the first way to get the stokes velocity. Thank you very much for your reply!

Dear jcwarner,
Thank you very much for your quick reply and I apologize for my delayed apprecaition. I set #define NEARSHORE_MELLOR to act on the radiation stress but it neads Dwave in my force file. How can I get the variable? Must I use the coupling model?

Hello, everyone I want to calculate Lagrange residue current in a tidal bay. So I should calculate stokes velocity first. In ocean.in file, I turn on Hout(idU3Sd)=T, Hout(idV3Sd)=T (3D U/V stokes velocity), but the variables can't be written in his-file. Why? Is it because I didn't turn on some CPP?...

My colleague, Charles James, has just completed writing a version of Seagrid in Matlab 2014b. I have no doubt that his version will suffer none of the issues (bugs, infuriating complexity, etc.) that plague Seagrid. I have seen it, and it looks great. I think the GSHHG coastlines and etopo 1 or 2 o...

Hello,everyone.I'm a new user using the seagrid to generate grids for ROMS, I have some problems in seagrid2roms, and I beg for anyone who is experienced for help. I installed the seagrid with matlab 7.1 in win32 system, and I download the mexcdf,snctools,netcdf_toolbox through svn (e.g.): svn co ht...
