Ocean Modeling Discussion

Greetings ROMS Discussion Community, I'm currently working on implementing latitude-varying air pressure in my ROMS model to create a pressure gradient for driving geostrophic currents. To achieve this, I've constructed the air pressure in the ana_pair.h file as follows: #elif defined SHALLOW || SHA...

Hello ROMS Discussion Community, I'm encountering a persistent issue with the sea surface height (zeta) output from my ROMS model, particularly regarding the boundary conditions. My aim is to fix the sea surface height to zero at the north and south boundaries using the Chapman boundary condition, a...

This works! Thanks a lot for your help.

Hello everyone, I'm new to the ROMS community and currently attempting to implement analytical air pressure changes in space, specifically across latitudes. To achieve this, I attempted to incorporate the latitude variable into my pair functions. Here's what I've tried so far: CALL ana_pair_tile (ng...

Running with both BODYFORCE and a vertical turbulent mixing closure scheme might be inconsistent. Using MY25_MIXING (or GLS_MIXING or LMD_MIXING) assumes the stress is applied as the surface boundary condition to vertical momentum mixing. Thanks so much for your reply! For your comments on BODYFORC...

Hello everyone, I'm currently working on configuring ROMS to include the calculation of the surface boundary layer (Hsbl) and bottom boundary layer height (Hbbl) in the output files rom_his.nc and roms_avg.nc. However, despite enabling these options, I'm unable to see the results in the output files...

Thank you for providing clarification. I have an additional question that has arisen. I'm curious about where I could define my bustr and bvstr variables. It appears that it's not as straightforward as editing the ana_smflux.h file, unlike sustr and svstr.

Dear ROMS community, I hope this message finds you well. I'm currently in the process of incorporating the force due to sea surface tilt as a body force in my ROMS model. I've initiated this process by defining 'BODYFORCE' in my .h file. Additionally, I've made adjustments to the parameter LEVSFRC. ...

I truly appreciate the time and effort you took to assist me with my query. Your solution worked perfectly for me, and I was able to manage the force now. Thank you!

Hello everyone, I'm a new user on this platform and currently in the process of building my own model based on the upwelling testing case. However, I've encountered an issue that I'm seeking assistance with. Specifically, I want to disable the westward wind force in my model's forcing file. I believ...

Hello ROMS community, I'm encountering an issue with the output file generation in ROMS and would appreciate some assistance. After running the model, I've noticed that no output files are being generated in the designated folder. I've checked the roms.in file and ensured that the output file switch...

Hello, I'm a newcomer to ROMS and currently learning the basics of setting up ROMS. I apologize for posing what might be considered a fundamental question. As I work on creating my roms_model.in file based on the roms_upwelling.in test cases, I've encountered a challenge with the lateral boundary co...

Got it! Thank you for your guidance!

Thanks a lot for your prompt reply! I truly appreciate your assistance. Your suggestion to use c_grid for creating a new grid was helpful. Now, I have a follow-up question. If I make changes to specific parameters, such as f, mask_v, or lon_rho these kind of variables, within the grid structure, how...

Hi ROMS community, I'm a new user in ROMS and I'm currently working on setting up an idealized grid for the ROMS model using MATLAB and have run into a bit of a roadblock. I'm trying to save the grid structure to a NetCDF file, as required by ROMS. On the ROMS wiki [https://www.myroms.org/wiki/Grid_...

I think I got what you mean. I've been trying to create a new gid. Is there a Matlab function for me to create it? Additionally, I've seen that "write_contact.m" is also for a nested grid. So I was confused is there a function for helping me to write the grid I've made to save as the nc fi...

Hello, I'm encountering some issues with creating an idealized grid for my ROMS model using MATLAB scripts from [https://www.myroms.org/wiki/Grid_Processing_Scripts](https://www.myroms.org/wiki/Grid_Processing_Scripts). When attempting the `c_contact("grid_ideal.nc",1,1)` command, I encoun...
