Anthropogenic influence of temperature changes across East Asia using CMIP6 simulations

Observed and model simulation trends

Figure 1a, b show the annual mean temperatures averaged for 1901–2014 estimated from Climatic Research Unit (CRU) and CMIP6 historical simulation (ALL forcings = anthropogenic + natural), respectively. The mean temperature varied between − 15 and 25 °C throughout EA. Southeast China showed the highest mean temperature (approximately 25 °C), while Tibet and northwest Mongolia showed the lowest (< 0 °C). In Korea and Japan, the mean temperature varied from 4 to 16 °C. The performance of the CMIP6 model simulations (ALL forcing) was validated in comparison with the CRU observations. The bias (ALL − CRU) across EA and in all EA countries is shown in Fig. 1c, d. In Fig. 1d, the 25% and 75% quartiles indicate a bias of < 1.8 °C. Overall, the mean bias for EA was ≤ 0.5 °C, indicating that the performance of the CMIP6 simulations was satisfactory. Figures 1a, b also…
