To investigate the effect of meteorological factors, seasonal factors and Air Pollutions on the formation of particulate matter (PM2.5) in Jinan, China. Nonlinear dynamic inversion model was established to analyze the effect of meteorological factors, seasonal factors and CO, PM10, SO 2 , NO 2 , O 3 on PM2.5 formations in different seasons. Temperature has a great influence on PM2.5 concentration variation. Precipitation exacerbate the formation of PM2.5 in Winter. Wind speed make a little contribution to PM2.5 formation in Jinan during different season. The formation of PM2.5 was influenced by confounding factors.
