The length scale comparisons indicate that the scales are too short in the coarser resolution run, especially in lower latitudes. In the higher resolution case, the length scales are generally close except for a few outliers.
The drifter length scales have a range of 10 to 80 km, with the most representative scales lying between 20 and 50 km. The 0.1° scales show a similar distribution however in the meridional case there are more occurrences of scales in the 30-40 km range and less in the 10-30 km than in the observations. The distribution of the 0.28° scales shows a range of 10-50 km with most of the occurrences between 10-30 km. These results indicate that the 0.28° length scales are too short relative to the observations, while the characteristics of the 0.1° model scales are in much closer agreement with those from the drifters.
