摘　　要：The recent study ＂Trends of Extreme Precipitation in Eastern China and Their Possible Causes＂ attributed the observed decrease/increase of light/heavy precipitation in eastern China to global warming rather than the regional aerosol effects. However, there exist compelling evidence from previous long-term observations and numerical modeling studies, suggesting that anthropogenic pollution is closely linked to the recent changes in precipitation intensity because of considerably modulated cloud physical properties by aerosols in eastern China. Clearly, a quantitative assessment of the aerosol and greenhouse effects on the regional scale is required to identify the primary cause for the extreme precipitation changes.The recent study ＂Trends of Extreme Precipitation in Eastern China and Their Possible Causes＂ attributed the observed decrease/increase of light/heavy precipitation in eastern China to global warming rather than the regional aerosol effects.
