The values are Pearson correlation coefficients calculated by relating the mean series of ring-width indices (RWI) and monthly values of maximum and Tns with water balance. ND and D are non-declining and declining trees, respectively. Correlations were calculated from the prior (t–1) to the current September. Significant correlation coefficients are shown as bold values.
