Although the occurrence of positive correlations between SST and near-surface wind speed (w) over oceanic mesoscale ranges is well-known, the intrinsic spatial and temporal scales over which this air-sea coupling regime takes place are not well established. The contribution of the near-ubiquitous mesoscale ocean eddies in driving the observed coupling characteristics, relative to that of larger-scale ocean phenomena such as extratropical SST fronts and Rossby waves, also remains unclear. This work addresses these gaps using cross-spectral statistics calculated between SST and w from satellite products, and from two CCSM4 simulations based on identical atmospheric components but with contrasting horizontal ocean resolutions of 0.1 degree, capable of resolving mesoscale eddies (HR), and of 1 degree, whose eddy effects are parameterized (LR).
