#1959 assigned Task

ENHANCE-09_Jerome_freesurface(2017WP)

Reported by: cbricaud Owned by: jchanut
Priority: high Milestone: Unscheduled
Component: OCE Version: trunk
Severity: minor Keywords:
Cc: Branch review: failed
MP ready?: no Task progress: Tasks 1) and 3) are already completed and available in NEMO 4.0, hence only task 2) (pressure gradient gradient correction) is remaining. Implementation plan is in progress.

Description (last modified by jchanut)

Summary

Action ENHANCE-09_Jerome_freesurface
PI(S) Jérôme Chanut

Digest

Improve split-explicit free surface:
1) Tracer conservation issues (all time splitting options do not ensure global and local tracer conservation): DONE
2) Missing correction terms in the barotropic equations relative to internal pressure gradients. This would reduce mode splitting error, hence improve stability
3) Work on the stability of barotropic time stepping (based on INRIA's work) to possibly remove time filtering of barotropic variables. This would limit the temporal dissipation and greatly ease online coupling of nested domains at barotropic level (with AGRIF). DONE
