| 摘 要： | 暴雨的历时，面积和深度的关系（时、面，深）是水文气象学的重要研究课题之一。近年来，从熵最大原理的角度曾推导出其中的两个负指数关系，并被大量的观测所证实。本文通过对５个个例的分析发现，降水过程的另外两组变量也服从负指数关系。即不同的降水历时与其占有的面积之间和不同的降水强度与其占有的面积之间都遵从负指数关系。而这两组新关系显然对暴雨预告有实用价值。

| Abstract: | The relationship among the duration the area and the depth of the hard rain is a important research subject in hydrometeorology. Recently, the two negative-index relations have been deduced by the principle of the maximum entropy and confirmed by a lot of observation. In this paper, it is found from analyses for 5 examples that the another two sets of variation in precipitation process obey negative-index relation, too. Namely, the relationship between the different precipitation duration and its area and the relationship between the different precipitation intensity and its area both obey all the negative-index relation. The two sets of new relation are practical worth on the hard rain forecast. |
