摘要/Abstract

摘要： 利用2017―2020 年南通市国控点的逐时臭氧 (O3) 浓度监测资料和同期的南通市国家基本气象站的逐时气象资料，分析了南通市O3污染的年际变化、月变化、日变化以及O3污染特征与气象因素的关系。研究结果表明： (1) O3浓度季节变化幅度表现为夏季 > 春季 > 秋季 > 冬季，日变化呈现出单峰特征，通常在上午06：00―07：00 出现最低值，而在15：00 左右出现最高值； (2) O3浓度与温度呈正相关，与相对湿度呈负相关，当温度大于20 ℃，相对湿度在30% ～50 %之间，风速处于0～4 m/s之间时， O3浓度较高，容易出现超标的情况。

Abstract: Based on the hourly ozone (O3) concentration monitoring data of the national control points in Nantong City from 2017 to 2020 and the hourly meteorological data of the national basic meteorological station in Nantong City, China, during the same period, the interannual variation, monthly variation, daily variation of ozone pollution changes in Nantong City were analyzed, as well as the relationship between O3 pollution characteristics and meteorological factors. The results show that: (1) The seasonal variation amplitude of ozone concentration is summer > spring > autumn > winter, and diurnal variation of O3 shows a unimodal trend, with the lowest value usually occuring during 06: 00 – 07: 00 am and the highest value around 15:00. (2) The O3 concentration is positively correlated with temperature, and negatively correlated with relative humidity. When the temperature is greater than 20 °C, the relative humidity is between 30% and 50 %, and the wind speed is between 0 m/s and 4 m/s, the O3 concentration is often high, and excessive conditions are likely to occur.
