| 摘 要： | 本文根据卫星云图分析以及对尘暴气溶胶和尘暴路径地区表层土的元素组分分析,进一步讨论了1980年4月18日出现在北京地区上空强尘暴的来源。结果表明,这次强尘暴的来源是比较复杂的,它不只是来源于某一单一地区,而是由尘暴起源地区及其移动路径地区的沙土微粒经大风输送到高空并进行混合,然后随着大风移动而造成的。

| Abstract: | In this paper origin of a dust storm occurring April 18, 1980, once over Beijing area was discussed again based on analysis of the satallite cloud picture and elemental composition of the aerosol in the dust storm and the surface soil of the path areas. Results of analysis show that the origion is complicated to explain. It originated not only from more than one area, but also was found formed of sand particles brought along and mixed together by strong wind all the way from of the areas where the strong wind was formed and passed. |
