Fig. 2

a Time series of June–August aggregate sinuosity (Sag) (orange) and Greenland Blocking Index (GBI; black) plotted alongside June North American (blue) and Eurasian (green) SCE area. Dashed lines show raw annual data. Solid lines show 5-year running means. b Correlation matrix comparing each of the raw annual time series in (a) (i.e., before taking a running mean and without detrending). White numbering presents the correlation coefficient for each variable pair and color shading corresponds to the strength of correlation. NA denotes North American SCE; Eur denotes Eurasian SCE. All correlations are statistically significant at the 95% confidence level.
