Initialized Decadal Predictions by LASG/IAP Climate System Model FGOALS-s2: Evaluations of Strengths and Weaknesses

Figure 9

Left panel: the spatial pattern of IPO mode in the observation (a) and corresponding time series (blue line in (b)). The IPO mode is defined as the second EOF mode of 4-year running-averaged annul near global SST (50°S–50°N). The black line in (b) is Mega-ENSO index, defined as the difference in the SST anomalies between the western K-shape zone and eastern triangle zone in (a). Right panel: the same as the left panel, but for the FGOALS-s2.
