a Spatial pattern of the first leading EOF mode of March North Atlantic SST. Value in the upper right is the explained variance. b Time series of the normalized NA_PC1 (red solid curve) and NATSI (black solid curve). The shading represents ±0.8 standard deviations. Correlations between the March NATSI and the following c autumn and d winter SSTs. e–f Similar to (c–d) but for the partial correlations with the signal of previous winter Niño3.4 index removed. The stippled areas in (c–f) denote the significant values exceeding the 95% confidence level.
