摘要: 以2010年春季3~5月间,辽宁省沈阳市、盘锦市、铁岭市3城市发生的3次沙尘天气为主要研究对象,利用安德森大流量采样器采集大气中悬浮颗粒物样品,分析不同沙尘天气状况下的颗粒物粒径组成,并结合气象状况采用后推气流轨迹模型,通过沙尘来临时3城市上空不同高度的后推气流轨迹,分析得出3城市沙尘的主要来源为蒙古高原与西伯利亚地区,输送方式以高空远距离输送为主,并伴随部分低空近距离传输和本地扬尘共同作用。

Abstract: In this research, 3 times of dust weather which occurred in Shenyang, Panjin and Tieling of Liaoning Province during March and May of 2010 were taken as the study target. Suspended particulate samples in the air were collected by use of Anderson high-volume sampler for size composition analysis of the dust particles under different dust weather conditions. With regard to the meteorological conditions, backward air trajectory model was applied for analysis. According to the back trajectory at different height above the three cities when the dust came over, the results showed that the dust mainly came from Mongolian Plateau and Siberia Region, and long-distance transportation at high altitude was given priority to the transportation mode, accompanied with the combined action of partial short-distance transportation at low altitude and local fugitive dust.
