	The MKE (cm^2s^-2) from the drifters, the 0.28° and 0.1° models are compared. The MKE values are easily understood in the light of the mean fields; the unrealistic features of the 0.28° model produce higher MKE values than those produced by the drifters at those locations. The high drifter MKE values in the GS show a step-like pattern consistent with its north-easterly flow whereas the 0.1° field displays a consistent band of higher MKE along its more zonal GS path. A difference plot of the drifter and the 0.1° MKE fields (not shown) shows the southerly displaced GS between 60° to 45°W to have unrealistically high MKE values relative to the observed GS flow in this longitude range. However at the GS separation, the model MKE is lower than those of the drifters.
From the histograms of the drifter and model MKE values it can be seen that the distributions are very similar, indicating that the differences between the observed MKE and the modeled MKE lie mainly in the spatial patterns, which can be understood particularly in the GS context. The distribution of the 0.1° values more closely matches the drifter values.
