Description
What is this about???
Dear reader,
This is an important enhancement of LIM3 to improve its stability in ORCA2 configuration at least. By default, the horizontal gradient of sea surface height is not activated. It should.
How to activate that???
- Uncomment the two lines starting with zdsshx and zdsshy in limrhg.F90.
- Define ssh_m in sbc_oce.F90:
REAL(wp), PUBLIC, DIMENSION(jpi,jpj) :: ssh_m !: mean (nn_fsbc time-step) sea surface height [m]
- Compute ssh_m in sbc_ssm.F90 (see attached file)
Bur is there any effect ???
Of course, yes!!! It definitely stabilizes the sea ice near the Canadian Archipelago and reduces the chances of model crash.
Merci pour votre collaboration!
Salutations distinguées,
Martin!
