摘要
本文讨论了自然正交函数的优缺点,并将它用于我国梅雨天气分析。结果表明:自然正交函数作天气分析是可行的。这种方法能得到与天气学分析一致的结果。这是一种统计学分析方法,若与天气动力学方法相结合,可望在天气分析与预报中发挥更大的作用。
In this paper,the advantages and shortcomings of empirical orthogonal function have teen discussed.This function was applied to the diagnostic analysis of"plum rains"in China.The results indicate that the empirical orthogonal function is useful in the diagnostic analysis.With this approach the results which are in agreement with synoptic analysis can be obtained.This is a statistical method.It would play a greater role in weather analysis and forecast,if it is combined with synoptic and dynamic methods.
