Westerlies

We noticed that Agulhas leakage is indeed higher in the year 2000 CO₂ level control runs, but no significant increasing trend in the climate change simulation. It might be due to the equilibrium timescale of westerlies to changing CO₂, or an internal bias of our high-res CCSM.

The interannual variability of Agulhas leakage is accessed in an ocean eddy resolving coupled simulation to test the hypothesis that, on such timescales large-scale forcing dominates leakage variability, regardless of eddy structures.
