Main Conclusions:
Figure 1. The linear trends of SLP (shaded; hPa (44 year)-1) and 850 hPa winds (vectors; m s-1 (44 year)-1) in JJA during 1958-2001. (a) Observations (SLP and 850 hPa winds from ERA40); (b) all-forcing run; (c) anthropogenic-forcing run; (d) GHG-forcing run; (e) natural-forcing run; (f) aerosol-forcing run from MME. The green box in (a) and (b) is northern China (32°N-42°N, 105°E-122°E).The dotted areas indicate that the precipitation trends are statistically signi?cant at the 10% level. The MME is constructed by using 35 realizations from 17 CMIP5 models (see Auxiliary Material for details).
Figure 4. (a) Scatter plot of the linear trends of SAT (K (44 year)-1) averaged over eastern China (28°N-38°N, 105°E-122°E) and SLP (hPa (44 year)-1) averaged over northern China (32°N-42°N, 105°E-122°E) in JJA during 1958-2001. The dots indicate 17 models in different forcing runs identified by different colors. The lines indicate the best linear fit lines between SAT and SLP. The fitting coefficients are given in the brackets; (b) Linear trends of SAT averaged over eastern China (28°N-38°N, 105°E-122°E) in the observation, all-forcing run, anthropogenic-forcing run, GHG-forcing run, aerosol-forcing run and natural-forcing run of MME (The SAT averaged over the EASM region (0°-50°N, 90°E-160°E) have been subtracted). The MME is constructed by using 35 realizations from 17 CMIP5 models (see Auxiliary Material for details).
