“…Additionally, they also showed asymmetrical warming in the diurnal temperature cycle, yet largely underestimated the magnitude of the observed decreasing trend in the DTR (Stone and Weaver 2002;Braganza, Karoly, and Arblaster 2004;Zhou et al 2009). Changes in T max , T min , and DTR can be influenced by land surface conditions, cloud cover, precipitation, aerosols, greenhouse gas emissions, and other natural and anthropogenic factors (Dai, Trenberth, and Karl 1999;Roy, Robert, and Balling 2005;Zhang and Wang 2008;Zhang, Wang, and Wu 2009;Wu, Zhang, and Dong 2011;Tang and Leng 2012;Hua and Chen 2013;Wang et al 2013).…”

“…Compared to the daily mean surface air temperature, much less attention has been paid to the diurnal temperature range (DTR), which reflects the difference between daily maximum (T max ) and minimum (T min ) temperatures (DTR = T max -T min ) (Karl et al 1991;Easterling et al 1997). T max is largely determined by the solar radiation reaching the land surface, whereas T min is closely associated with nighttime longwave radiation (Dai, Genio, and Fung 1997;Zhang and Wang 2008).…”

Introduction: Daily maximum (Tmax) and minimum (Tmin) temperatures and Diurnal temperature range (DTR) profoundly affect the ecological environment and socioeconomic systems. In this study, we project future changes in Tmax, Tmin and DTR for RCP4.5 and RCP8.5 using fine-resolution downscaled data from the 18global coupled models over the main regions of the Belt and Road Initiative (BRI). Outcomes: The Multi-Model Ensemble (MME) mean projections show that future warming is stronger in Tmax than in Tmin, leading to the increased DTR over central and southern Europe, many areas surrounding the Black Sea and the Caspian Sea, and southeastern China. By contrast, the DTR is projected to decline over the regions north of 55°N and other some areas due to the more rapid increase in Tmin than in Tmax. As a whole, the diurnal asymmetry of projected future temperature changes is found to mainly occur from November to March. Conclusions: Our findings contribute to the knowledgebase on climate change over the main BRI regions. Regarding uneven spatiotemporal changes in Tmax, Tmin and DTR, appropriate climate change adaptation strategies, and options should be adopted to reduce or avoid disadvantaged consequences to the natural system and human society over specific regions.

“…The increases in mean state of surface air temperature correspond well with the increases in local surface sensible heat and the decreases in local latent heat, and vice versa (Figures a, a, and c). In addition, the stronger cooling effects on T min than that on T max over western Inner Mongolia (Figures c and e) may relate to the variation of atmospheric water vapor that impacts the nighttime T min through the greenhouse effect (Zhang & Wang, ), and the changes in water vapor here may relate to the local factors, such as the latent heat flux. On the other hand, if there were changes in ground temperature or land surface emissivity induced by soil moisture variation, they may also influence the T min by regulating the outgoing longwave radiation (Zhou et al, ; Zhou et al, ).…”

The increased mean temperature and temperature variability under global warming can have many adverse impacts on human and natural systems. However, how soil moisture‐atmosphere interaction can affect future climate change over East Asia remains largely unclear. We use long‐term regional climate simulations with the Community Climate System Model‐Weather Research and Forecasting (CCSM‐WRF) model system to investigate the role of soil moisture feedbacks in future summer surface air temperature change over East Asia. Results show that summer surface air temperature and precipitation are projected to increase over most of East Asia by the end of 21st century under the Representative Concentration Pathway 8.5 (RCP8.5) scenario. Soil moisture feedbacks lead to an increased summer mean temperature of 0.15°C averaged over East Asia, with key regions appearing over the northern part of Tibetan Plateau, Sichuan Basin, and the middle and lower reaches of the Yangtze River Basin during 2071‐2100 under the RCP8.5 scenario. And regionally averaged interannual temperature variability induced by soil moisture feedbacks is substantially enhanced as a whole. Regarding the spatial distribution, soil moisture feedbacks on interannual temperature variability are projected to strengthen notably over the northern part of Tibetan Plateau, the Hexi Corridor, and Sichuan Basin and weaken over the south Tibetan Plateau, southeast China, and the areas surrounding the Lake Baikal. The stronger responses of surface heat and the atmospheric boundary layer to dry anomalies than wet anomalies lead to an obvious dry‐wet asymmetry of soil moisture feedbacks on summer surface air temperature over the key areas of East Asia.
