Ocean Modeling Discussion

Hello I am working on COAWST model on Japan sea. I have been working on this project for 3months and I had problem on ROMS. Which below down here. I cant upload my files here because size is too big. Blowing-up: Saving latest model state into RESTART file REASON: KEchar = NaN, PEchar = NaN WRT_RST ...

Dear jcwarner, arango

Thanks to Arango and jcwarner, I was able to do it successfully.
The cause of the error was a violation of the CFL condition due to the small timestep.
Thank you guys.

Gosh, you need to pay attention to what ROMS tells you in the standard output. Where in the ocean can we have velocities of 93 m/s , and what does that mean? Your application is blowing-up because of a violation of the CFL condition. If you don't know what a CFL condition is and how to remediate it ...

I see still: GET_GRID - bathymetry at RHO-points: h (Grid = 01, File: Projects/Katrina/roms_grid_Katrina.nc) (Min = 5.95202990E-03 Max = 3.35037820E+03) that is a min of 0.005 m . I dont think you need a min of 5 mm. try again. in the grid file to set h to have a minimum depth. maybe something like ...

I have emailed you the climatology, boundary conditions, and initial condition files that I used.
I created these using the seapy utility.
Are there any strange parts?

GET_GRID - bathymetry at RHO-points: h (Grid = 01, File: Projects/Katrina/roms_grid_Katrina.nc) (Min = -2.15744419E+02 Max = 3.33282292E+03) you need to activate wet dry if you have negative h values. Suggest you take a look at your grid and decide if you are really resolving wet/dry processes. if ...

Hi everyone I'm trying to run ROMS alone in the COAWST model. The header file (.h) is set to #define ROMS, and the others are set to #undef. coast.bash was able to compile successfully, and I prepared various necessary files and tried to execute the calculation. Then an error occurred. Below are my ...

Dear , the error code 400 in your message means the server didnt find what you are requesting. The 400 Bad Request Error is an HTTP response status code indicating that the server was unable to process the request sent by the client due to invalid syntax. I don't use python and matlab to download ...

Dear s19364, there are two sets of HYCOM GLBv 0.08 expt 53.x, one has ice and the other doesn't . The set which has ice doesn't have SSH. Make sure you are using the correct one. Dear isoares thank you for your reply. I used the Print command to check the URL that was being read earlier, but I ...

oops, not enough coffee yet. those ecmwf is for bulk fluxes. there are other posts on getting hycom data, such as: https://www.myroms.org/forum/viewtopic.php?p=23944&hilit=hycom#p23944 https://www.myroms.org/forum/viewtopic.php?p=23938&hilit=hycom#p23938 https://www.myroms.org/forum/viewtopic.php?p ...

the tools we have there are for aggregated data https://tds.hycom.org/thredds/catalog.html i dont see the 60.5 on that list. -j Dear warner Certainly, there doesn't seem to be 60.5 in that list. How should I get the HYCOM data needed to create the 2005 clm data? Should I use GLBu0.08 expt_19.1? If ...

Thank you for reply

Dear ROMS Users I have a question about creating climatology data. I would like to download the 2005 data in HYCOM data GLBa expt60.5 using COAWST/Tools/mfiles/roms_clm/roms_master_climatology_coawst_mw.m in a MATLAB 2022a environment. So, I edited and executed the url, wdr, and modelgrid parts of ...

Dear "Icbernardo"(Lawrence) Thank you for your repeated replies. I'm sorry, but rewriting the matlab script in python is not very easy for me. Regarding another proposal, I checked the code such as getHYCOM.F90 in ROMS_prep / src. I'll check if it can be executed with these once, but I prefer to be ...

This is the Fortran code

You can probably try the tools available from this GitHub page: https://github.com/NakamuraTakashi Dear "lcbernardo" thank you for your reply. Is the tool you are talking about [matlab (ROMS matlab script)]? Or is it [ROMS_prep (Utility for ROMS preprocessing)]? I'm sorry, I don't have MATLAB. So ...

Nice to meet you I recently started using the COAWST model and met ROMS in it. So I'm not familiar with ROMS and I don't know how to prepare the input data. Currently, I am using the pyroms tool. I want to reproduce Hurricane Katrina in 2005. Therefore, I am thinking of using the data of GLBv0.08 ...
