a Three leading SST ISOMAP PC trajectories between May 2019 and December 2022. SST anomalies reveal El Niño events, normal events, La Niña events, normal events again, and then La Niña events. El Niño, normal, and La Niña event are marked by red, yellow, and blue points, respectively. b RMSE and ACC values from the NN during this period. c NN prediction trajectory (blue curve) and true observation (red curve) during this period
