Interannual time series of (a) winter AO, MEI, and PDO indices, and A-YSCWM and T-YSCWM in August (b) summer AO, ENSO, PDO, and the A-YSCWM and T-YSCWM in August. Time series of the A-YSCWM and T-YSCWM are standardized. The A-YSCWM and T-YSCWM represent the area and averaged temperature of the YSCWM, respectively. The “+” represents the El Niño events, and the “” represents the La Niña events.
