摘要
论述了与水利水电工程设计和运行密切相关的降水和暴雨季节变化的地域分布，其中包括旬降水量和最大１ｄ暴雨量多年平均值、暴雨年际变化、时－面－深关系等要素的季节变化；提出了降水季节集中系数分布图；讨论了降水、一般暴雨和稀遇暴雨季节变化的异同。
Regional distributions of the seasonal variations of precipitation and rainstorm which are closely related to the designs and operations of water resources and hydroelectric projects are studied, including seasonal variations of the rainstorm elements: means of ten day precipitation and maximum 1d rainfall, inter annual variation of rainstorm, depth area duration relationship, etc.. The map of the seasonal concentration coefficient of precipitation is shown, and the similarities and differences for the seasonal variations among precipitation, ordinary rainstorm, and rare rainstorm are also discussed.
