摘要：
Evaluating the schemes and characteristics of models that are applied in studying the mechanism of how climate change would impact air pollution is key to providing a better understanding of the current studies and supporting modeling research in the future. This study reviews existing modeling studies on the topic “climate change impact on air pollution” based on literature investigation. Three types of modeling studies at different spatial scales – global and regional – are identified, and the characteristics and applicability of different research methods are compared. Furthermore, using data from the CMIP5 climate model intercomparison project and the atmospheric chemical transport model WRF-Chem, the impacts of future changes in meteorology and pollutant emissions in the context of climate change on near-surface summertime O3 concentration in China in 2050 are studied, with the Beijing-Tianjin-Hebei region, Yangtze River Delta region, and Pearl River Delta region selected as representatives for analysis. Results show that under the RCP8.5 climate change and emission pathway, both meteorological and emission changes will impose significant effects on summer ozone concentrations in China by the middle of this century. In most regions of China, changes in emissions would have a significant influence on ozone concentration, but the meteorological field near the East China Sea would also significantly affect future ozone pollution. In addition, a certain degree of interaction between the two factors exists. © 2023 Peking University. All rights reserved.
