Extended Data Figure 4: Correlations between gridded proxy and model hydroclimate anomalies, and gridded hydroclimate temperature proxy anomalies.
From: Northern Hemisphere hydroclimate variability over the past twelve centuries

a, Correlations between 45 centennial, lagged 25 years, weighted gridded proxy hydroclimate anomalies and their corresponding median total annual precipitation anomalies from six CMIP5 models, listed in Table 1, over the past twelve centuries. b, The Z-transformed block bootstrap p-values of the correlations shown in panel a. c, Correlations between 45 centennial, lagged 25 years, weighted gridded proxy hydroclimate anomalies and weighted gridded proxy temperature anomalies. d, The Z-transformed block bootstrap p-values of the correlations shown in panel c. Areas shown in grey in b and d have insignificant correlations.
