| 摘 要： | 通过对哈尔滨市1954-2003年沙尘暴、大风及降水等气象观测资料的分析认为,哈尔滨市沙尘暴发生次数的年代变化明显,沙尘暴的发生与大风风速、风向与降水均有显著的相关关系,同时与大气稳定度有关,也受下垫面性质的影响.通过对沙粒尺度的分析,认为哈尔滨市沙尘暴的远距离沙源为内蒙古境内沙地、科尔沁沙地,近距离沙源在松嫩平原和哈尔滨周边地区. |

| Abstract: | By studying the data of dust-storm,strong wind and precipitation in Harbin form 1954 to 1999, it can be known that the occurring time of the dust-storm in Harbin is different with decades, and it has correlation with the speed and the direction of strong-wind and precipitation; In the same time, the dust-storm is influenced by the atmospheric steady degree and the nature of the surface of the earth. Based on the analysis of sand particle, it is pointed out that the distant sand source of dust-storm hitting Harbin is the Nei Monggol and Gerqin deserts, and the near source is in Songnen plain and surroundings of Harbin. |
