Overview
In addition to the ocean boundary conditions, 3D salinity and temperature are nudged to HYCOM values in a small region within 1.5 degree in longitude from the eastern boundary:
Generating nudging inputs
A group of scripts are provided under this folder (HYCOM_nudge/) for automatically generating the nudging inputs. You can put the folder into your run directory, then do:
[your_run_dir]$ cd HYCOM_nudge/
[your_run_dir/HYCOM_nudge]$ ./auto.pl
This will make the following files and save copies in your run directory (you can read "auto.pl" to see what steps are involved):
- SAL_nudge.gr3 and TEM_nudge.gr3, which specify the nudging strength (as in the above figure)
- SAL_nu.nc and TEM_nu.nc, which contain the values to be nudged to.
