南涧县主要气象要素的正态分布检验及正态化处理

The research of normality and normalization of main Meteorological elements in nanjian county

利用Jarque-Bera检验法对南涧县1962-2014年逐月、年平均气温、降水、日照等气象要素样本进行正态分布检验,发现平均气温和日照样本均服从正态分布,降水样本正态性差。利用平方根和立方根方法对降水样本进行正态化处理,处理后样本均服从正态分布,两种处理方法效果相当。

appliy Jarque-Bera Method to research on the Normal distribution test of main Meteorological elements data from 1962 to 2014 month by month and year by year in nanjian county,found that the air temperature and sunshine durations were normally distributed,but most precipitation sequence were not. After having them square root and cubic root be transformed, they all follow normal distribution.
