| 摘 要： | 本文用黄河上游(兰州以上)及其附近地区34个站25年以上的降水资料,分析了本区多年平均的年、月、旬降水(变率)特征。指出本区的部份地区有初夏旱、伏旱和秋雨现象;本区的月降水变率远大于年变率,而旬降水变率又大于月变率,特别强调了在盛夏和秋雨期,主要产流区各月都有一个高变率中心。这些都给水文、气象预报带来很大困难。

| Abstract: | Using the precipitation and variability materials ( 34 stations, over 25 years ) of the upper reaches of the Yellow River, we've studied the characteristics of the secular mean yearly, monthly, decade precipitation and variability; we've set up the rainy season, the region of drought (Early Summer ) and Autumn rain.
We've pointed out that the secular mean monthly variability is much more bigger than the yearly variability and emphasised that there is a big center of the monthly variability nearby Ma Qu station ( over 36% ) from July to September. These caused a lot of difficulties of the hydro-meteor forecast. |
