摘要: 水文对我国近200个站点1956~1980年的月平均雨量进行了谐波分析,揭露了前三波相对方差初相的地理分布特征及其与大气环流的某些联系.这一方法有助于定量地分析降水的季节变化特征.

Abstract: Using the data of mean monthly precipitation for 1959—1980 close to 200 stations,a harmonic analysis of the precipitation field in China has been made.The characteristics of geographical distribution of relative variance and phase angles of the first three waves and some relationships between these characteristics and general circulation are studied.This analysis is helpful to describe seasonal variation of the precipitation quantitatively.
