Information Entropy Analysis on Nonuniformity of Precipitation Dis tribution in Time-Space, Ⅱ, Model Evaluat ion and Application

The Information transfer function model is set up on the base of numerical simulation,so that the information transfer study is transisted from dispersed states to continuous.The information distance and the information field are defined,and the information transfer is extended from only one direction to an area.Finally the nonuniformity on precipitation distribution is studied further using the clustering method.
