Table 1

Summary statistics from the multivariate regression using the NAO, the NP and the SO indices as the independent variables and NH (20° N to 90° N) temperature anomalies as the dependent variable. Also shown is the correlation matrix and the partial correlation coefficients. The index that is held constant is indicated by the subscript.
