| 摘 要： | 在数值模拟的基础上提出了信息传输函数模型,使信息传输研究从离散状态过渡到连续状态.引进了信息距离与信息场的概念,将站点的信息传输从单一方向推广到周围区域,最后利用聚类分析法进一步刻划了降雨的空间分布不均匀性.

| Abstract: | 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. |

| Keywords: | precipitation time-space distribution information transfer model entropy |
