Temporal and Spatial Variation Characteristics and Meteorological Impact Analysis of O_3 Concentration in Tangshan

Zhang Li;Wang Guan;Chen Zhen;Wang Siyao;Tangshan Meteorological Administration;  
Based on the near-surface ozone( O_3) time-lapse observation data and meteorological data of Tangshanin in2016,the temporal and spatial distribution characteristics of the near-surface O_3 concentration in Tangshan area and its relationship with meteorological conditions were analyzed. The results show that the average concentration of O_3 in Tangshan area is higher than that in the suburbs above the central urban area. It has obvious monthly variation characteristics,O_3 pollution mainly occurs in May ~ September,and the highest concentration of O_3 in June is 167. 19 μg·m~(-3). The daily variation of O_3 concentration was"unimodal",with the lowest value at 6: 00 ~8: 00 and the peak concentration at 15: 00. O_3 concentration is positively correlated with temperature and negatively correlated with relative humidity. When the pressure is lower than 1 005 h Pa,O_3 concentration is positively correlated with air pressure. When the air pressure is higher than 1 005 h Pa,it is negatively correlated with air pressure. O_3 concentration is basically wind power of level 2 or higher and blowing. The concentration in the northwest,southwest,and southeast is higher.
