| 摘 要： | 文中以和田地区8个气象观测站1960~2005年的沙尘暴天气资料为研究对象,应用CRESSMAN函数和数理统计方法进行统计分析,得出和田地区沙尘暴天气的时空分布特征。结果表明:1)和田地区属于沙尘暴的高发区,区域之间沙尘暴分布不均匀;2)和田地区全天都有沙尘暴发生,大多出现在17~22时;3)和田地区沙尘暴天气主要出现在3~9月,高发期在4~8月,最活跃的是5~6月,春夏多、秋冬少;4)年际变化呈现出波动减少的趋势,1988年后减势明显;5)沙尘暴的多发年代在20世纪60年代,进入90年代沙尘暴的发生明显减少,平均每10 a减少近4.4d;6)多数沙尘暴天气持续时间在4h以内,平均在1~3h之间,最长持续时间超过9h,民丰长达28.3h。

| Abstract: | Based on sandstorm data of 8 weather observation stations in Hotan region from 1960 to 2005,the CRESSMAN function and mathematical method were used to statistically analyse,and educe the sandstorm time-space distribution in Hotan region.The results indicated: 1)Hotan region was the region with high occurrence of sandstorms,the district distribution of sandstorm was asymmetry;2)Sandstorm happened whole day in Hotan area,mostly happened in the 17 to 22 o'clock;3)Sandstorm happened mainly from March to Septemb... |
