应用K均值聚类法对东亚各自然天气季节500毫巴候平均环流的分型试验

A PATTERN CLASSIFICATION OF THE MEAN PENTAD CIRCULATIONS AT 500 mb LEVEL OVER EAST ASIA FOR EACH NSS BY THE METHOD OF K-MEAN CLUSTER ANALYSIS

摘要: 利用自然正交函数法划分了东亚自然天气季节以后,本文应用K均值聚类法对各个自然天气季节内部的500毫巴候平均环流进行了分型试验,得到了一些有意义的结果。

Abstract: After dividing NSS over East Asia by the method of EOF, an attempt of pattern classification of the mean pentad circulations at 500 mb level for each NSS is made by the method of K-mean cluster analysis. Some interesting results have been obtained.
