摘要
The influence of air pollutants, especially aerosols, on regional and global climate has been widely investigated, but only a very limited number of studies report their im pacts on everyday weather.In this work, we present for the first time direct (observational) evidence of a clear effect of how a mixed atmospheric pollution changes the weather with a substantial modification in the air temperature and rainfall.By using comprehensive measurements in Nanjing, China, we found that mixed agricultural burning plumes with fossil fuel combustion pollution resuhed in a decrease in the solar radiation intensity by more than 70 %, a decrease in the sen sible heat by more than 85 %, a temperature drop by almost 10 K, and a change in rainfall during both daytime and night time.Our results show clear air pollution-weather interac tions, and quantify how air pollution affects weather via air pollution-boundary layer dynamics and aerosol-radiation cloud feedbacks.This study highlights cross-disciplinary needs to investigate the environmental, weather and climate impacts of the mixed biomass burning and fossil fuel com bustion sources in East China.
