摘要
Abstract
Based on the monitoring data of national air monitoring station in Wuhu City from 2016 to 2021 and the meteorological data of the same period,the characteristics of ozone pollution at different time scales in the region were studied.Statistical methods such as correlation analy-sis were used to explore the effects of meteorological factors and the concentration of NO2 and other precursors on ozone.The results show that the annual variation of ozone concentration and days exceeding the standard in Wuhu City is repeated,and the trend is rising in recent years.Ozone concentration is highest in summer,followed by spring and autumn,and lowest in winter.The variation of monthly concentration showed an"M"type bimodal variation,and the highest value appeared in May-June and July-September.The diurnal variation of ozone concentration was uni-modal,with sharp changes during the day and gentle fluctuations at night,reaching the peak at 16:00.The main meteorological factors affecting ozone concentration are 14 hours air temperature,average air temperature,sunshine hours and relative humidity.Ozone concentration was nega-tively correlated with NO2,CO and PM2.5,and the correlation with NO2 was the best.关键词
