First empirical orthogonal function (EOF) mode of sea surface height (SSH) anomalies in 140°E-170°E, 30°N-40°N obtained from a OFES2, b satellite observation, and c FORA. d Normalized annual mean of the first principal component (PC) of SSH anomalies in 140°E-170°E, 30°N-40°N obtained from the OFES2 (black line), satellite observation (light blue line), and FORA (green line). The horizontal black dotted lines represent ± 1 standard deviation, and the red (blue) dots represent the stable (unstable) states
