Abstract

Based on the hourly ozone (O3) concentrations and meteorological variables observed at a coastal location (Jida) and an inland location (Doumen), this study investigated the O3 pollution characteristics and their relationships with meteorological factors in Zhuhai via an integrated application of statistical analysis, case analysis, HYSPLIT back trajectory analysis and potential source contribution factor analysis (PSCF) method. The results indicated that ①the high temperature and low humidity conditions in dry season are favorable for the O3 formation, causing a higher O3 concentration and pollution frequency in Zhuhai; ②the O3 concentration and pollution frequency are significantly higher at the inland site of Doumen; ③wind field exerts important influence on the O3 distribution in Zhuhai while the highest O3 concentrations usually occur in the downward area when northeast wind or northerly wind prevailed with a wind speed of 3 ~ 4 m•s-1; ④the analysis of O3 heavy pollution case in October shows that the regional transport has large contribution to O3 pollution in Zhuhai. Clustering analysis of HYSPLIT back trajectories shows that the air mass source affecting the O3 pollution in Zhuhai region is the most polluted when it is affected by the air flow from the middle and eastern part of Guangdong Province, which is consistent with the results of the analysis of potential source contribution factor analysis (PSCF) that the potential sources of this pollution are distributed in the central-eastern Guangdong (e.g., Donguan, Zengcheng and Heyuan) and areas in the north of Heyuan.
