Fig. 1: Projected warming and scaling of precipitation with temperature.
From: Summer and winter precipitation in East Asia scale with global warming at different rates

a, b Future changes of surface temperature in the CESM1-LES RCP8.5 simulations (red contours, unit in degrees K) and percentage change of precipitation scaled by unit temperature change (color shading, unit in %/K) in JJA and DJF. The changes are calculated as the differences between the two periods of 2070–2099 and 1975–2004. The thick black contour is the 7.3%/K scaling of atmospheric water vapor content in JJA. Stippling represents statistical significance at 5% level in student t test with respect to the 40 ensemble variances. c, d Same as above, but for the scaling of the total moisture flux divergence (convergence) in JJA and DJF.
