摘要
利用2006～2008年2月逐日地面常规观测资料和高空探测资料以及逐日的污染监测资料,统计分析了哈尔滨市2月风速、逆温和大气稳定度与大气污染的概率关系。分析结果表明:哈尔滨市2月的大气污染主要发生在风速<3 m/s,污染物浓度随着风速的增大而减小,在一定程度上反映了哈尔滨市2月的污染主要是局地污染物的累积;发生大气污染时一定有逆温出现,但有逆温时不一定就发生大气污染;大气稳定度增加,大气污染概率增大。
Based on the daily surface and high observations and air pollutant observations in February of 2006～2008,the Relationship between Temperature inversion and Atmospheric stabilities and Pollution Probability in Harbin were analyzed.The results showed that atmospheric pollution occur mainly in wind speed 3m/s,Pollutant concentration decreases as the wind speed increases,A certain extent,that reflect the pollution in Harbin in February was mainly local cumulative pollutant;Atmospheric pollution occur when the temperature inversion must have occur,but temperature inversion did not necessarily occur when there was Atmospheric pollution;Pollution Probability increased as the atmospheric stability increased.
