Based on the data of environmental monitoring stations and meteorological stations in Qinhuangdao from May 2017 to May 2020, the variation characteristics of O3 and precursors (NO 2 and CO) as well as their relationship with meteorological elements were analyzed. The results showed that the daily average concentration of O 3 -8 h in Qinhuangdao increased year by year. The monthly average concentration of O 3 -8 h was high in summer and low in winter, and the peak appeared in June. The diurnal variation of O 3 concentration was unimodal structure, and the concentration increased in the afternoon, but it decreased at night. The concentration of NO 2 and CO was inversely correlated with O 3 , and the peak value of NO 2 in March could be related to frequent cold air activity and increased burning of loose coal. The meteorological elements favorable for the occurrence of ozone pollution weather in Chengde were total solar radiation irradiance greater than 1000W/m 2 , the daily maximum temperature greater than 33 °C, and the daily minimum relative humidity less than 40% and 65%∽80%, southerly wind or southwest wind.
