| 摘 要： | 利用2014—2020年河北沧州逐小时气象与环境监测数据,对沧州市臭氧(O3)污染加剧现状及其与气象因子的关系进行分析。结果表明:(1)沧州地区O3污染呈加剧态势,且O3已上升为该地区首要污染物;O3污染集中出现在5—9月,O3质量浓度日变化呈单峰单谷型,最大浓度出现在16:00前后;(2)5—9月O3日最大8 h平均质量浓度(简称“O3-8 h”)所处时段,平均气温、最高气温、相对湿度、总辐射辐照度与O3质量浓度的相关性较好,本站气压、水汽压和平均风速与O3质量浓度的相关性未通过显著性检验;(3)5—9月O3-8 h时段,当同时满足8 h平均气温高于30.9℃、最高气温高于32.7℃、平均相对湿度低于42.1%、平均总辐射辐照度高于505.8 W·m-2时,出现O3污染的概率达84%;(4)气象因子不是O3小时质量浓度快速增长的充分条件。

| Abstract: | Based on hourly meteorological and environmental monitoring data in Cangzhou of Hebei Province from 2014 to 2020,this paper analyzed the aggravation of ozone(O3)pollution and its relationship with meteorological factors.The results are as follows:(1)The pollution of O3 in Cangzhou had been increasing and O3 had become the primary pollutant.The pollution of O3 concentrated from May to September,and the diurnal variation of O3 mass concentration showed single peak and single valley type,and the maximum concentration occurred around 16:00 BST.(2)During the period of O3-8 h maximum value from May to September,the average temperature,maximum temperature,relative humidity and total radiation irradiance were strongly correlated with the O3 mass concentration,while the correlation between station atmospheric pressure,water vapor pressure,mean wind speed and the O3 mass concentration didn’t pass the significance test.(3)During the period of O3-8 h maximum value from May to September,when the average temperature of 8 h was above 30.9℃,the maximum temperature of 8 h was above 32.7℃,the average relative humidity of 8 h was below 42.1%and the average total radiation irradiance of 8 h was above 505.8 W·m-2,the probability pollution of O3 was up to 84%.(4)Meteorological factors were not sufficient conditions for rapid increase of O3 hourly mass concentration. |
