[A-AS04] Formation of Air Pollution and Its Interactions with Weather/Climate

コンビーナ:Yang Yang(Nanjing University of Information Science & Technology)、Meng Gao(State Key Laboratory of Environmental and Biological Analysis)、Guangxing Lin(Pacific Northwest National Laboratory)

Air pollutants, such as aerosols and ozone, have significantly affected environment, human health, ecosystem, and climate. Anthropogenic emissions of air pollutants in major economic regions of the world, which have changed rapidly over the past few decades owing to economic development and environmental measures, will continue to change in the near future. Air pollution from the changing sources not only degrades local and remote air quality, but also modifies energy balance, cloud, precipitation and circulation patterns, leading to regional and global environmental and weather/climate change. Climate change and variabilities in the changing world can in turn affect the emission, chemistry, transport and removal of air pollutants at different scales. To better understand the formation of air pollution, and air pollution-weather/climate interactions, advances are needed in theoretical, observational and modeling studies.
Relevant topics include but are not limited to:
(1) formation mechanism of air pollution, both physical and chemical;
(2) source attribution of air pollutants in the past and future;
(3) impact of air pollution on weather (boundary layer, cloud, precipitation, etc.), modes of variability and climate change;
(4) influence of historical climate variability on air pollution (ENSO, PDO, AO, etc.);
(5) predictability of future climate change associated with projected emission changes and feedback on air pollution.
