Ocean Modeling Discussion

Thanks, Prof Wilkin and Zhiyun, for your reply. I have checked my river points with the roms_plot_river_source_locations.m, and it shows the desirable points now. Previously, I didn't incorporate case (b) from this figure https://www.myroms.org/wiki/River_Runoff#river_Xposition_and_river_Eposition ....

Hello everyone. I want to give river in my domain using LuvSrc = T option and the LtracerSrc = T for both salinity and temperature. For checking, I have used the Matlab function map_rivers.m. The direction of the rivers is attached here. I m literally confused about the direction and the position of...

Hello everyone. I have run the ROMS model for 15 years using daily climatological forcing files. The model is looking stable after a few years. But after the 8th year, the model loses heat over my study region (southeastern Arabian Sea). So my doubt is can I take the results of the 8th year as stabl...

Thank you, Prof. Wilkin, for your response. I will definitely try the lwrad_down as you advised. Before that, I would like to mention to you that I have already used the solar source and WTYPE = 1. I have also mailed you the log file. I hope this will help you understand my model setup in detail. Pl...

Thank you for your response, Wilkin. IMDAA has both net Surface Net Long Wave Radiation Flux and Surface Downward Long Wave Radiation Flux. However, as you mentioned, I have used the net longwave radiation flux. In the varinfo.dat, I have seen the variable radlw_in for downwelling longwave radiation...

Hello everyone. I am setting up the roms model for the Indian Ocean region using climatology files. I have given initial and boundary files from World Ocean Atlas 18. The atmospheric forcing file is from IMDAA and Scatscat (for wind). When I am spinning up the model, the biases grow with time. For e...

Yeah, currently I am looking at the Matlab file sponge.m following the link for calculating the visc_factor. Hope to sort it out soon. Thanks for your reply.

Thanks yuchengzhang for your quick response. But can you please tell me how to add a sponge layer in bathymetry. I mean I have to add the sponge layer in the tool where I have made the grid file.

Dear all, I am trying to set up the ROMS model over the Indian Ocean. At 1/6 degree resolution, my model is running, but at 1/4 degree resolution, it is blowing up after some time steps. I have played with the time steps from 40 to 600 secs but nothing changes except a small shift in the point (i.e....

Thank you Dr. Joonho and Dr. Warner for your attention to my post. It took some days for me to resolve this blow up issue. I have changed the boundary schemes and now the model is running fine.

Thank you Dr. Joonho for your quick reply. I have checked the freshwater input flux and the values are similar to other forcing files i.e., shortwave radiation and taux. I created an another forcing file using era5 total precipitation and evaporation but the model is still showing same large minimum...

Thank you Dr. Warner for your quick response. As you suggested, I have checked the point (127,16) and it lies near the coast more specifically the Somalia coast (as my domain is Arabian Sea). The u momentum and v momentum component has very large deviation there, i.e., -21m/s and 15 m/s respectively...

Hello everyone. Recently I have encountered with the model blow up issue. I am new to modelling and want to couple wrf and roms using coawst (MCT). For that i want to run roms model individually, but after 6400 steps, the model blows up at a certain point near the coast. I masked that point and then...
