Fig. 1From: Interannual variation of the Warm Arctic–Cold Eurasia pattern modulated by Ural blocking and the North Atlantic Oscillation under changing sea ice conditionsObserved and simulated winter temperature change over the BKS and CEU. a, b Linear trends of winter SAT (shading; °C/decade), SLP (contour; hPa/decade; 0.2 intervals with negative values shown by dashed lines), and 850-hPa wind (vector; m/s/decade) for observations (a) and 100-member ensemble mean (b) during 1979/1980–2019/2020. Areas indicated by the green and orange lines in (b) denote the locations of the BKS (70°–80° N, 30°–70° E) and CEU (40°–60° N, 60°–120° E), respectively. c, d Interannual variation of observed and simulated winter SAT over the BKS and CEU, respectively, during 1979/1980–2019/2020. Green and orange lines denote observed winter SAT over the BKS and CEU, respectively; black lines denote the 100-member ensemble-mean; 25th–75th percentiles and 5th–95th percentiles of the ensemble spread are indicated by dark and light shading, respectivelyBack to article page
