Abstract:Using environmental monitoring data and meteorological observation data from 2017 to 2019 in Taizhou urban area,the temporal variation characteristics of ozone(O3) mass concentration in Taizhou urban area were analyzed,as well as the effects of temperature,sunshine,relative humidity,wind speed and direction,and precipitation on O3 mass concentration.It was found that O3 mass concentration was higher in summer and spring than in autumn and winter,and temperature and sunshine hours were positively correlated with O3 mass concentration.Relative humidity,wind speed and O3 mass concentration were negatively correlated,and precipitation had a significant inhibitory effect on O3 mass concentration.It is hoped that the research results can provide reference for O3 pollution forecasting and early warning work.
