Figure 01

Coupling weights for each coupling region used in the experiments: (a) GL90; (b) AO_PO90; (c) IO90. The MC-KPP SST is multiplied by the weight shown and the prescribed SST by (1−weight), and the sum of the two is the boundary condition to the atmospheric grid box. A 10o width (12 grid points) blending is applied at any boundary that is not a coastline. The weights for 200 km and 40 km experiments arethe same but with 5- and 30-point blending respectively.
