Meteorological Variables and Synoptic Patterns Associated with Air Pollutions in Eastern China during 2013-2018.

Steady meteorological conditions are important external factors affecting air pollution. In order to analyze how adverse meteorological variables affect air pollution, surface synoptic situation patterns and meteorological conditions during heavy pollution episodes are discussed. The results showed that there were 78 RPHPDs (regional PM pollution days) in Jiangsu, with a decreasing trend year by year.
