| 摘 要： | 本文统计并分析了安徽及不同区域夏季降水量的均方差、全距、两极比、绝对/相对间隔平均变率、倾向率、平均值与二分位值、各年代平均距平和序列累积距平等常用统计参数;并视降水统计总体接近正态分布.给出了安徽及各区域夏季累年平均降水概率50%、95%下的变化区间.讨论了各区域夏季多雨或少雨趋势的准周期振荡并对21世纪初期趋势作出预测.

| Abstract: | This paper analyzes the common statistical parameters of standard error,all difference,extreme ratio?absoulute and relative mean interval variability, relative variability, climate trend rate, mathematical average, meddle term, accumulate anomalies et al. for summer precipitation in differenct districts of Anhui. It shows the up and down limitation of summer precipitation is under the probability 50% and 95%, respectively assumes the normal distribution of precipitation, discusses the quasi cycle and expects the precipitation trend of the former period of the 21th century. |
