As in Fig. 6 but using the CESM1 Large Ensemble. a Ensemble-mean of scaled-interannual regressions of winter SLP (contours) and SAT (color shading) anomalies upon the normalized leading PC of winter SLP anomalies during 1920–2012; b SLP and SAT trend regressions upon the normalized leading PC of winter SLP 30-year trends based on 2016–2045; c as in (a) but for precipitation in place of SAT; d as in (b) but for precipitation in place of SAT. SAT in units of °C per 30 years, precipitation in units of mm day−1 per 30 years, and SLP contour interval of 1 hPa per 30 years with negative values dashed. e Histogram of the NAO trend PC (gray bars) and the expected distribution based on the interannual statistics of the NAO during 1920–2012 (blue curve); f as in (e) but after smoothing the trend histogram with a 3-point boxcar filter.
