为了全面、系统地分析冰雹现象的发生发展条件，利用朝阳地区1998-2013年间的冰雹个例，采用主成分分析方法，对所必须考虑的20个探空物理量因子进行降维，转化为能够基本保留原始物理量信息的6个综合指标：层结指数、高度指数、能量指数、温湿指数、热动指数、综合指数。总结出朝阳市16年间36次冰雹灾害中，有7次主要受层结指数影响，8次主要受高度指数影响，4次主要受能量指数影响，7次主要受温湿指数影响，5次主要受热动指数影响，5次主要受综合指数影响。

In order to comprehensively and systematically analyze the hailstorm development conditions,using the hail of Chaoyang City from 1998 to 2013 and the principal component analysis method,dimension of 20 considered sounding quantity factors were reduced and transferred to six comprehensive indices of physical information such as stratification,height index,the energy index,temperature humidity index,thermal index. It’s concluded that in the 36 times hail of Chaoyang City during the past 16 years,there were seven times mainly affected by stratification index,eight times mainly affected by high index,four times mainly affected by the energy index,seven times mainly affected by temperature humidity index,five times mainly affected by thermal dynamic index,five times mainly affected by composite index.
