New Surface Module
We put here description of the work done around this package. Mainly some figures ...etc
CONTEXT:
Experiments: REF_CORE (reference version) & SBC_NEW (new surface module)
Configuration type: Configuration ORCA2_LIM with bulk CORE
"Forcing spefs:" precipitation and snow are monthly value without time interpolation else
it will be different in SBC_NEW and REF_CORE.
In T2X experiences:
In doing the following modifications in both experiments, we are waiting for almost exactly the same results.
# The wind stress ([uv]tau/gtau[xy]) and wind module (zwind_speed_t(:,:)/dUnormt(:,:) at the ocean surface (even
above sea-ice) is forced to be the same in both experiments. (sbcblk_core.F90/flx_core.h90)
# The friction velocity ust2s(:,:) between sea-ice and ocean is also forced to be the same (limdyn.F90)
In FULL experience: done for REF_CORE and SBC_NEW:
We fully relax constrains imposed in T2X experiences, i.e. on stress, frictional velocity and so on ...
In FULL_SDP experience:
similar to FULL but with a strong restoring SSS damping of ~ 787 mm/day correponding to 12 days of time restoring
It is the same time damping as the SST which corresponds to -40 W/m2/K used for SST over a 10 meters ocean water column.
Modifications have been necessary in sbcssr.F90 module such as using the array sdta(:,:) computed in dtasal.F90 to ensure same
SSS damping field in both experiments SBC_NEW and REF_CORE.
In FULL_SDP2 experience:
Still SSS damping term without the ice-dynamics, i.e. ln_limdyn=.FALSE. in the sea-ice namelist.
In FULL_SDP3 experience:
Only for the SBC_NEW code, this time this run is identical to FULL_SDP but in sbcblk_core.F90, the sea-ice
velocity ([uv]i_ice()) has been removed in the computation of the wind stress and wind module over sea-ice.
Since the computation is clearly done in a better way now, it could implies important modifications which should be identify.
FULL_SDP Experiences:
Ice thickness in NEW_SBC experience / Year 10
The sea-ice extension in winter seems to be larger in this run than in the REF_CORE one.
Ice thickness in REF_CORE experience / Year 10
Ice thickness in NEW_SBC experience / Year 10: NO SEA-ICE DYNAMICS = ln_limdyn=FALSE
