| 摘 要： | 对天津地区出现的天气系统进行分类,利用后向轨迹模型对到达天津地区的气团轨迹进行模拟,并按照不同天气类型进行聚类,分析不同天气类型下到达天津地区的气团传输路径.结果表明,到达天津地区的气团主要来自西北和东南方向.对采暖期和非采暖期不同天气类型的出现频率及其对大气中ρ(PM10)的影响进行了研究.结果表明,天气类型是影响天津地区ρ(PM10)变化的重要因素.2008年采暖期的有利天气类型出现频率为84.2%,比非采暖期(66.9%)多17.3%;同期不利天气类型出现频率为15.8%,比非采暖期(32.2%)低16.4%.虽然采暖期颗粒物排放源强有所增加,但是有利天气类型出现频率明显高于非采暖期,而不利天气类型出现频率较低,这是2008年采暖期ρ(PM10)比非采暖期略低的重要原因.

| Abstract: | In this study,the weather system in Tianjin area was classified,and the air mass tracks arriving at Tianjin were simulated using backward trajectory models and clustered according to different synoptic patterns.The long-distance transport paths of air masses arriving at Tianjin with different synoptic patterns were analyzed.It was found that the air masses arriving at Tianjin were mainly from the northwest and southeast.The occurrence frequency of different synoptic patterns and its impact on the concentrat... |
