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

Figure 8

Lag correlations between the AMV index and anomalous northward oceanic heat transport (units: PW) from 20°S to 80°N for the ensemble mean of the INIT runs. The AMV index is averaged over the hindcast years 6–9 (red line in Figure 5(c)). Lag 0 represents simultaneous correlation. Lags 2 and 5 represent that the AMV index lags the heat transport anomalies by 2 and 5 years, respectively. That is, the heat transport anomalies are averaged over the hindcast years 6–9 (lag 0), 4–7 (lag 2), and 1–4 (lag 5), respectively.
