We present in this chapter a study on connections between the wintertime East Asian air pollution phenomenon and the monsoon strength. East Asia has been experiencing a fast worsening of air quality in recent years, particularly in winter, a problem commonly attributed to the increase of pollutant emissions associated with the rapid economic development. Meanwhile, previous studies have shown that the decadal-scale weakening of the Asian monsoon also contributed to the increase of PM2.5 (particulate matter with diameter less than 2.5 μm), a major pollutant that determines the air quality. Using a global modeling system, we investigate the emission and meteorological effects on the wintertime surface PM2.5 concentrations in East Asia in the past 30 years and find their relationship to the monsoon strength. We also examine the feedbacks between aerosols and meteorological fields via aerosol-radiation interaction to estimate the effects of such interaction on air quality.
