气象条件对深圳近地面臭氧浓度的影响分析

Analysis of the Influence of Meteorological Conditions on Ground-surface Ozone Concentration in Shenzhen

以深圳近地面臭氧浓度和气象条件为研究对象,分析了深圳臭氧污染与气温、相对湿度、风速、气团轨迹等气象因素关系。结果表明,深圳臭氧污染与气象要素密切相关,一般在气温高于24℃,相对湿度在55%~85%,日平均风速低于2m/s,受到偏北气团影响时,深圳易出现臭氧污染。

In this paper,the ozone concentration and meteorological conditions in Shenzhen were studied.The rela-tionships between ozone pollution,air temperature,relative humidity,wind speed and air mass trajectory were ex-amined.The results showed that the ozone pollution in Shenzhen was closely related to the weather elements,in general,when temperature was higher than24degrees Celsius,relative humidity was55%~85%,the average dai-ly wind speed was less than2m/s,and the air mass was from north,Shenzhen was prone to ozone Pollution.
