摘  要:
利用南京市国家环境空气自动监测站的观测数据,对2016年8月南京市发生的一次持续性O_3污染过程进行分析。结果表明:南京市O_3时间上呈单峰型日变化,空间上呈区域性污染特征;前体物NO_x日变化呈现双峰型分布,和O_3浓度呈负相关关系;气象条件的综合作用是O_3污染重要因素,持续的高温、较强的紫外辐射、适中的相对湿度、较低的风速以及主导风向高浓度O_3的输送,是此次O_3污染浓度高、持续时间长的重要原因。

摘  要:
A continuous O_3 pollution process in August 2016 of Nanjing was analyzed on the basis of the observative data from Nanjing National Automatic Environmental Air Monitoring Stations. Results showed that concentrations of O_3 during those days have both unimodal daily variation and regional pollution characters. Two peaks of NOx concentrations daily were observed, and the concentrations of NOx was negatively related to those of O_3. The comprehensive effects of meteorological conditions were important to O_3 pollution. All continuous high temperatures, strong ultraviolet radiation, moderate relative humidity, low wind speeds and high-concentration O_3 transmission in the dominant wind direction were important reasons for the high concentrations and long duration of O_3 pollution.
