Ocean Modeling Discussion

Hi chaos22u,

I have successfully used this script :- http://www.mathworks.com/matlabcentral/ ... 14-utm2deg developed by Gabriel Ruiz Martinez.

Good luck!

John, My company Numerics Warehouse Ltd. has and continues to use the coupled ROMS-SWAN system for a number of ocean energy related projects including :- (1) Extreme storm simulations to evaluate the 3D current field at sub-sea turbines close to the French coast for a tidal turbine developer. (2 ...

Hi, We would like to define a SWAN grid exactly the same as our ROMS grid so that we can couple the two. Our ROMS grid is curvilinear. On reading the SWAN manual, I think I have to set COORDINATES CARTESIAN and CGRID CURVILINEAR followed by READGRID from a file generated from the lat-lon ROMS rho ...

Rich, A good idea to make a list of (pre-) operational ROMS models. We have been running our model for the NE Atlantic since Jan 2007. The simulations can be viewed at :- http://www.marine.ie/home/services/operational/oceanography/OceanForecast online validation can be viewed at :- http://www.marine ...

The Marine Institute is looking for a developer with experience of ROMS to implement an ecosystem model (probably BFM) for the purpose of supporting decision making with respect to rapid climate change. If you are interested, please find details of the position and how to apply at http://www.marine ...

Hi Ratnam, We use PMEL's Ferret (http://ferret.wrc.noaa.gov/Ferret/) to do this. It is very fast, free and can be installed on desktops or 64 bits servers. The regridding to a regular lat lon grid is done in two stages :- firstly you need to make a mapping function, which can take a lot of ...

We have had problems with riverine input causing numerical instability and high salinities. Initially we just used the the interfacial wave speed to calculate the Courant Number and set the baroclinic time step accordingly - but still had problems. We found that we had neglected the effect the ...

There are a few places in the code where divisions take place and where the possibility exists that the divisor equals 0 (especially if you are starting with some initail data fields that are set to zero). Some places where this occurs are u2dbc_im.F, v2dbc_im.F, zetabc.F and rho_eos.F. When I had ...

I had similar problems with SSH in ROMS 2.1. I found that in the Make file, when compiling code with ifort, that no floating point checking was included as default. I added -fpe=0 to FFLAGS. What this does is it immediately aborts program execution when a floating point exception occurs, rather than ...
