| 摘 要： | 本文利用1958—1986年共29年甘肃省31个测站的夏季(6—8月)降水资料,运用自然正交函数方法进行展开。分析了展开后降水的空间分布特征与第一时间系数的变化规律,並与ENSO现象相对照,发现在ENSO现象发生之年甘肃夏季中部和陇东南降水明显偏少;而在ENSO现象次年夏季降水全省明显偏多。

| Abstract: | In this paper, we have analyzed the spacial distribution characteristic and the variations of the first time coefficients of total summery precipitation ( June-August 1958-1986 ) by means of EOF for 31 stations of Gansu province. Compared the results with ENSO phenomena it turned out that the summery precipitation over the central section and the south east part of Gansu province was less than the normals considerably in the years of ENSO phenomena, but it was more than the normals in the following years. |
