#660 closed Bug (fixed)

bug in NP folding for wind-stress in coupled mode

Reported by: smasson Owned by: smasson
Priority: normal Milestone:
Component: OCE Version: release-3.2
Severity: Keywords: NP_folding coupled_mode stress wind
Cc:

Description

Theses bugs affect the north pole folding of the wind stress, only the coupled model if wind stress is sent in the eastward-northward. In this specific case, it can affect or not the stress over ocean and ice according to the different options you use…The safest is to do a test in your own case.

2 bugs:
1) in OPA_SRC/SBC/geo2ocean.F90. I introduced a bug in changeset:672. Cos AND sin must be multiplied by -1 in the call of lbc_lnk (we add pi to the angle when doing the north pole folding).
2) in OPA_SRC/SBC/sbccpl.F90: when receiving wind stress, and applying lbc_lnk, we must multiply by -1 ONLY if the wind stress is already on ORCA grid. If the stress is on eastward-northward grid, the multiplication by -1 will be done through the rotation (see 1st point). (reported by David Salas)
