| Zusammenfassung |
| 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 impacts 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 resulted in a decrease in the
solar radiation intensity by more than 70%, a decrease in the sensible
heat by more than 85%, a temperature drop by almost 10 K, and a change in
rainfall during both daytime and nighttime. Our results show clear air
pollution–weather interactions, 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 combustion sources in East China. |
