Table 1 Pearson correlations (two sided) between each pair of variables in the three cores during the entire time series (ETS: 1926–2017) and the phases of positive Indian Ocean Dipole (pIOD) dominance (1991–2017) and negative Indian Ocean Dipole (nIOD) dominance (1926–1990), respectively (n: number for statistical analysis; r: correlation coefficient; p: the level of significance; significant: p < 0.05; highly significant: p < 0.01; no significant: p > 0.05; bold numbers indicate a significant correlation between two variables).
