Fig. 7: The significant differences of precipitation at GW1.5 for the whole of China and especially for Southeast China under the transient scenario and stabilized scenario.
From: Recent frontiers of climate changes in East Asia at global warming of 1.5°C and 2°C
Relative changes of summer (JJA) precipitation (relative to 1986–2005, considered as present-day climate) at GW1.5 (relative to preindustrial), obtained with a CESM low-warming simulations (noted as CESM_LW, stabilized scenario), b CESM large-ensemble simulations (noted as CESM_LENS, transient scenario), and c CMIP5 models in their ensemble-mean form (noted as CMIP5_MME, transient scenario). The red box indicates south-eastern China (target domain 22–33°N, 105–122°E, land areas). d Percentage change in regional mean precipitation in China versus south-eastern China. Error bars denote the range of the ensemble members, and the bar heights are the median of the ensemble. e Schematic diagram showing mechanisms that increase JJA total precipitation over south-eastern China at GW1.5 under a stabilized warming scenario compared to a transient scenario. Red (blue) contours indicate positive (negative) surface temperature anomalies. Purple and black dotted arrows represent the enhanced Walker circulation and westerly jet, respectively. Green curved arrows represent moisture transport. The solid circle with arrows represents the anticyclone over the western North Pacific (WNPSH). This figure is adapted from Figs. 1 and 10 of Jiang et al. (2021).
