Ocean Modeling Discussion

Note that there was a code update 6 weeks ago to introduce COARE3.5 bulk fluxes: https://www.myroms.org/projects/src/ticket/970 The changes from 3.0 to 3.5 make the algorithm more appropriate at higher wind speeds. If your issue is arising in shallow water you might need to limit the bottom stress ...

What winds are you using? I have heard that ERA5 can get unphysically large. Since I wrote that prior message I switched to a Large and Yeager bulk flux scheme, then I changed ocean models. Hi Kate! I use CFSR as bulk forcing and HYCOM as boundary condition, which were all downloaded from HYCOM web...

You think the effect of winds is too strong? How are you obtaining wind stress from wind? It is known that the BULK_FLUXES stress algorithm is too strong in the case of high winds, also it doesn't account for the currents (it is a function of winds only, not of winds-currents). This is your 2-D cas...

Using Hourly CFSR atmospheric bulk forcing to drive ROMS hindcast from 2004 to 2020, a sudden occurrence of NAN occurred at 2007 during the calculation process. Through experiments, it was found tthat it was a problem with the wind file (Replacing with ERA5 wind can run normally), but there was no N...
