The 5–95% range of interannual NAO regression values across the 40 members of the CESM1 Large Ensemble based on detrended data during 1920–2012. (a) and (b) show SLP (contours; interval = 1 hPa with negative values dashed) and SAT (color shading; °C) regressions associated with a −2 and +2 standard deviation departure of the NAO, respectively. c, d as in a and b but for precipitation (mm day⁻¹) in place of SAT.
