No flux correction is included. A 70 year simulation has been carried out with the climate model. The results appear realistic in many respects, although the model climate differs from nature in other respects. The model does display decadal variability similar to that found in other coupled GCMs. Figure 8, top panel, shows that decadal variability occurs in the northern hemisphere midlatitudes and the southern hemisphere near Antarctica.
Interannual variability is prominent near the equator.
The structure of the first model EOF involving tropical Pacific SST is shown in the lower panel. Note also the association of the tropical and northern hemisphere midlatitudes in this pattern.
