Table 1: (a) Mean absolute correlation at 95% significance level between annual and decadal (5-year running means) MO indices and climatic variables (, , -, and net heat flux, ). The fraction of points significantly correlated is shown in brackets. (—) indicates that the correlation is not significant in more than 95% of the basin. (b) The same as above but for winter (JFM) season. The highest correlation for each variable is highlighted in bold.
