Differences in atmospheric circulation between Historical and Hist-GHG simulations on 850 hPa (a–c), 500 hPa (d–f) and 200 hPa (g–i) for three time periods (the PD1, PD2, and PD3) are listed from left to right in each row. a–c Near-surface temperature (shading; K), mean sea level pressure (contour; hPa) and horizontal wind on 850 hPa (vectors; m·s−1). d–f Eddy geopotential height (He; shading; 10 m) and horizontal wind (vectors; m·s−1) on 500 hPa, the solid lines are contours of He = 0 m on 500 hPa from Historical (red) and Hist-GHG (blue) simulations to indicate boundaries of the West Pacific subtropical high (WPSH). g–i Zonal wind (u; shading; m·s−1) and horizontal wind (vectors; m·s-1) on 200 hPa. The dotted area indicates that the specific shading field has passed the significance test at the 95% confidence level based on a two-tailed Student’s t-test.
