Time-lagged correlation coefficients of the first (black solid line) and second (black dashed line) EOF modes of vertical velocity w with respect to Niño 3.4 index and that between the first and second EOF modes (pink solid line). The time series were smoothed by a 15-month running mean filter. The positive time lag with respect to Niño 3.4 index indicates that the EOF modes of vertical velocity lag the Niño 3.4 index. The positive time lag between the EOF modes denotes that the first mode lags the second mode. The vertical solid line denotes the zero time lag. The horizontal dotted and solid lines show the 95% confidence interval (\({\pm }0.46\)) and zero correlation, respectively
