摘要/Abstract

摘要： 通过对长三角城市群 2018 年臭氧和气象数据的监测与分析, 研究了该区域臭氧时空分布特征及其与气象要素的相关性。研究结果发现: (1) 长三角区域臭氧污染呈现春夏高、秋冬低的季节变化特征, 内陆城市臭氧污染较沿海城市严重; (2) 长三角区域内陆城市超标污染主要发生在夏季, 而沿海城市主要集中在春季, 且内陆城市臭氧超标天数较沿海城市高; (3) 臭氧日变化与能见度、风速、温度呈正相关, 与相对湿度呈负相关; 且当温度 > 20◦c, 相对湿度在 20%∼60% 之间, 风速达到 1.2∼3.6 m·s−1 时, 易发生高浓度臭氧污染情况。该研究成果对长三角区域臭氧联防联控具有指导意义。

Abstract: By monitoring and analysis the ozone and meteorological observation data of the Yangtze River Delta, China, urban agglomeration in 2018, the temporal and spatial distribution characteristics of ozone and its correlation with meteorological elements in the region are studied.The results show that: (1) The ozone pollution in the Yangtze River Delta region shows the seasonal variation characteristics of high in spring and summer, and low in autumn and winter, and the ozone pollution in inland cities is more serious than that in coastal cities. (2) In the Yangtze River Delta region, inland cities mainly suffer from excessive pollution in summer, while coastal cities mainly in spring, and the number of days of excessive ozone in inland cities is higher than that in coastal cities. (3) The daily variation of ozone is positively correlated with visibility, wind speed,and temperature, while negatively correlated with relative humidity. When the temperature is higher than 20◦c, the relative humidity is between 20% and 60%, and the wind speed reaches 1.2 m·s−1 to 3.6 m·s−1, high-concentration ozone pollution is prone to occur. The research results have guiding significance for ozone joint prevention and control in the Yangtze River Delta.
