Analysis of the Relationship Between the Acidity and Physical Character of Precipitation

Utilizing the monitoring data of the acidity of precipitation obtained by Changchun observatory and other stations in 1983—1985, the relationships among the precipitation amount, precipitation intensity, precipitation type, the seasonal variation of precipitation, the distribution of raindrop size and the acidity of rain have been analysed. Also, the effect of precipitation on the rainwashing pollutant has been discussed
