摘要
将聚类统计检验分析引入原有的基于聚类的浮动区对比历史回归人工增雨效果检验方法中,减小站点分区的盲目性,聚为同一类的站点相似度更大,使聚类分析具有统计学意义。并把这种方法和未引入聚类检验的方法进行比较,通过对河南4月10次作业的效果评估表明,引入聚类检验提高了效果评估的功效。
In this paper the statistical test of cluster analysis suggested by Professor Yao Zhensheng （1994） was used to improve the original Cluster-Analysis-based Floating Control historical regression Method. The new method can diminish blindness in precipition in the same cluster, and make the cluster cluster analysis, increase the correlativity of stations analysis have statistical meaning. The assessment of precipitation enhancement in the cloud seeding operation cases in April in Henan Province were performed using the new method and the original one, the results show that the evaluation effctiveness is improved greatly by introducing in the cluster test.
