surface boundary layer depth

Hi ROMS users I am saving Hsbl (depth of oceanic surface boundary layer) and Hbbl (depth of oceanic bottom boundary layer) variables in my average output file. I am using LMD vertical mixing scheme. When I plot Hsbl, I observe that some of the values (generally near river mouth) are positive and the...

matlab toolbox boundary/initial file

Hello ROMS users I have been using matlab toolbox for making surface forcing files for a while now. Recently I've decided to use the toolbox for making boundary as well as initial conditions files. Upon inspection, I've decided to modify d_mercator2roms.m for making initial file and d_obc_mercator.m...

You mean I can have forcing fields on a grid that is larger than my ROMS application grid?

Interpolation of forcing data to ROMS grid

Hi ROMS users I know that ROMS can interpolate the surface forcing data from a lat-lon grid onto a ROMS application grid, but I am confused as to the lat-lon extent of the forcing data that we can provide. For example, in my grid file, the corner latitudes and longitudes are LowerLeft(-30S,30E), Low...

Hi ROMS users I'm running a simulation wherein I provide the surface forcing i.e. stresses, E-P and net heat flux directly (i.e. without using Bulk Formulae). I am providing them after interpolating from data sets to ROMS application grid. I was wondering if it is possible to provide these forcing p...

Re: vertical section of a roms output variable

Thank you very much rsignell. Although I am looking for a way to do it using filled contours (without having to interpolate the variable on a fixed set of depth values), your notebook is very helpful. Thanks a lot.

Re: angle in grid file

Thank you very much kate and shchepet. I used to use roms_tools but the algorithm it uses to calculate the angle was difficult to understand. Now I use matlab routines by Arango, but couldn't find an algorithm to compute angle.

Thank you very much.

angle in grid file

Hi ROMS users In the ROMS grid file, the description of the variable 'angle' is the angle between XI-axis and EAST. My question is how do you determine this angle? If I want to run a simulation for Indian Ocean, how will I determine this angle? Also, should the units of angle be degrees or radians? ...

One equation would obviously be the salinity transport equation. But river runoff does impart some momentum to t...

Re: bulk forcing

Thanks kate. But, would it not affect the calculation of other fluxes, since many of them depend on the Monin-Obukhov similarity parameters (e.g. Wstar)? I want only stresses to be zero while retaining all other surface forcings.
