Abstract：In order to analyze the impact of rainstorm and snow meteorological factors on PM2，5 air pollution diffusion，the PM2，5 pollutantconcentrationdataandinstoandsowmeteorologicalfactoratawerepreprocessedtoextractthedatacharacteristicsofdaily and interanualfluctuations.Usingthestepwiselinearregresion（MLR）andLMGmethods，thispaperstudieshowspecificraistor and snow meteorological factors affect the concentration changes of PM2.5 pollutants in the study area from 2019 to 2023．The research results show that precipitation，wind speed，and temperature have the greatest impact onthe dailyvariationof PM2，5 air pollution diffusion insummer，while snowfall，wind speed，and humidity have the greatest impact on the dailyvariationof PM2.5 air pollution diffusion in winter.The mainrainstorm meteorological factors of the interannual variation of thedaily variation of PM2.5 concentration in summer and winterin the study area are precipitationand snowfall，respectively.
Key words：rainstorm and snow meteorological factors; PM2，5 ；pollution diffusion；precipitation；snowfall amount
