摘要
利用1961~2008年六枝站逐日雨凇观测资料,采用线性倾向估计等方法,对六枝雨凇天气的时空分布、变化趋势等进行了分析,结果表明:六枝雨凇主要出现在1月份;近48年雨凇日数呈下降趋势,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;1984年以后随着冬季气温增高,雨凇日数明显减少。
The temporal and spatial characteristics and change trends of glaze were analyzed by using linear trend analysis method based on the daily data in Liuzhi special zone from 1961 to 2008.The results showed that the occurrence of glaze was mainly in January and glaze days decreased gradually in recent 48 years.The most glaze days appeared from 1960's to the 1980's.The glaze days decreased significantly since 1990's.The glaze days significantly decreased with the increase of temperature in winter since 1984.
