降水量Γ分布模式的普适性研究

Research of Universality for Γ Distribution Model of Precipitation

本文应用概率论中著名的多项分布结合统计物理学观点证明降水量频数的最可几分布必然为Γ分布。文据实测资料验证降水量频数分布的最佳模式为Γ分布。从而提出适用于各地任意时段和任意月份的降水量Γ分布通用模式。文中还就有关问题作了有益的讨论。

It is shown that the most frequent distribution of the precipitation frequency distribution must be Γdistribuhon by using the famous multinomial distribution of probability the+ory as tved as the viewpoint of statistical physics. On the other hand, it is also tested that the ophmal model of the frequellcy distribution of precipitation is the Γ distribution according to statistical data. Thus, this paper proposes a universal model for precipitation Γ distribution which can be applied to various time interval and all monthly in each region.
