摘要
利用MODIS卫星、空气质量监测、天气图资料以及后向轨迹分析法,分析研究了2010年11月4～6日发生在京津冀地区和东北地区一次灰霾污染过程。初步的研究结果表明:在此次天气系统演变过程中,上述两地区的污染过程表现出内在的联系,即此次东北地区的灰霾过程主要是京津冀地区灰霾输送影响的结果,其影响通道是渤海湾及与其毗邻的辽河平原。这可在卫星云图、后向轨迹以及输送通道上PM10(可吸入颗粒物)浓度跃变的时间位相差异获得证明。这种灰霾污染的跨区域影响现象,给目前治理灰霾污染的区域调控战略提出了挑战。
One dust-haze episode occurring from North China to Northeast China plains during 4-6 Nov 2010 has been analyzed, using MODIS data, air pollution monitoring data, weather chart, and backward trajectory method. Preliminary result shows that this dust-haze episode in Northeast China is inherently related to that in North China, and the former is influenced by the transportation of air pollution form the latter. The air pollutant transportation channel between Northeast China and North China is the Bohai Bay and its neighborhood Liaohe Plain. This conclusion was proved by MODIS image, backward trajectory analysis and the phase delay of PM10（inhalable particulate） concentration upspring along the transportation route. This brings forward a challenge to the air pollution regional control strategy.
