| 摘 要： | 利用1961~2008年六盘水市3个测站的逐日雨凇天气现象观测资料,采用线性倾向估计、Mann-Kendall突变检验等方法,对六盘水地区雨凇天气的时空分布、变化趋势等进行了分析。结果表明,六盘水雨凇天气地区差异显著;出现雨凇日数最多的是水城,最少的是六枝。雨凇主要出现在12月~翌年2月;20世纪60~80年代雨凇日数最多,进入90年代以来雨凇日数明显减少。突变分析发现,六盘水冬季气温与雨凇日数均在1989年发生突变,1989年以后随着冬季气温增高,雨凇日数明显减少。

| Abstract: | Based on the daily glaze data in Liupanshui from 1961 to 2008 at 3 observational stations,the linear trend estimation and Mann-Kendall methods were adopted to analyze the temporal and spatial distribution,variation trend of glaze.The results showed that the difference of glaze was significant in different areas.It occurred most frequently in Shuicheng and the least one was Liuzhi.Moreover,glaze mainly occurred from December to February in next year and 1960s-1980s were the most glaze days.The glaze reduced ... |
