Figure 3: CCA Cross-Validation Skill in AMJ, MJJ, and JJA 2008 seasons for (a) mean sea level deviations and (b) maximum sea level deviations.
Figure 4 (below). Average Seasonal sea level deviation for the previous season (January-February-March 2008); SD stands for standard deviations.
* Forecast quality is a measure of the expected CCA cross-validation skill. In general terms, these kinds of forecasts are thought to be of useful skill (but poor) skill if the CCA cross-validation value is between 0.3 ~ 0.4. Higher skills correspond to greater expected accuracy of the forecasts. Skill levels greater than 0.4 and 0.6 are thought to be fair and good, respectively, while skill levels greater than 0.7 are thought to be very good.
