Along with the rapid economic development and accelerated urbanization process, many areas in the world are suffering from high levels of ozone and fine particle pollution. These air pollutants can affect weather and climate system through absorbing or scattering radiation. For example, ozone is a kind of greenhouse gases, while aerosols can not only directly affect solar radiation but serve as cloud ice nuclei or ice nuclei to modify microphysical processes of clouds and precipitation. On the other side, weather and climate are also closely linked to formation of air pollution. Monsoon climate, stagnant weather conditions and large-scale circulation patterns all play important roles in air pollution. Understanding how weather and climate interact with air pollution at present and in the future can help us in the field of air pollution prevention and mitigation of global warming.

This session aims to address the current challenges, methodological approaches and wider relevance of observing and modelling meteorology-atmospheric environment interactions around the world. We welcome contributions including, but not limited to, integrating multi-source data (such as, on-situ monitoring, remote sensing, etc.) with controlled experiments to identify the key processes, modelling of the interactions between climate change and air pollution as well as the future projections, assessment the impact of extreme weather on air pollution and future trends, and illustrating the development of cities and the effects of urban climate on regional air quality. Research that reveals the impact of air pollution on the environment, ecology and human health is also welcome.
