Fig. 1

Observed 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, respectively
