摘要: 选用中国178个常规气象观测站建站~2000年历年春季沙尘暴日数资料, 分析了近50a来中国北方春季沙尘暴的气候特征。在此基础上进一步揭示了我国北方沙尘暴的形成、发展以及造成的危害。结果表明: 我国北方春季沙尘暴存在东西反位相差异, 近50a来, 春季沙尘暴日数总体趋势在减少, 但20世纪末又有明显的回升趋势。这不仅与影响我国北方的冷空气路径有关, 还与青藏高原冬季地面感热的异常密切相关。

Abstract: Data of annual sand-dust storm days recorded by the 178 meteorology observation stations in northern China were used to analyze the climatic characteristics of sand-dust storm during spring in the recent 50 years and its response to the surface sensible heat on Qinghai-Xizang plateau in winter. Results showed that there was opposite phase of sand-dust storm happening between in the east and the west of northern China; generally the sand-dust storm days during spring had been decreasing in recent 50 years, but at the end of the 20th century remarkably showed re-rising trend. The happening of sand-dust storm in northern China not only has relation with the moving path of cold air but also with the surface sensible heat flux on Qinghai-Xizang plateau in winter.

Key words: northern China, sand-dust storm in spring, evolution tendency of sand-dust storm, Qinghai-Xizang plateau, surface sensible heat
