综述了降雨空间分布的意义及其对空间相关函数的影响。参考地统计学中最初采用的变分理论，对一些统计术语和性质进行了深入的解释。随后详细分析了理论变差模型、气象、地形和时空聚集尺度的影响，并讨论了网络设计、面积平均计算和风暴速度。然后检验了经验变异图和验证技术。对意大利北部伦巴第的两个不同地区（多山的瓦尔泰利纳流域和该地区大部分平坦地区）的一些应用进行了讨论，并对结果进行了讨论。在附录中，结合随机雨场空间分布的估计，说明了克里金技术。
The significance of spatial distribution of rainfall and its effects on spatial correlation functions are reviewed. A number of statistical terms and properties are explained in depth with reference to the theory of variograms originally adopted in geostatistics. This is followed by a detailed analysis of theoretical variogram models, effects of meteorological, orographic, and space-time aggregation scales and a discussion on network design, areal mean calculations and storm velocities. Empirical variogram and validation techniques are then examined. Some applications to two different parts of Lombardia (the mountainous Valtellina catchment and a large part of the flat area of the region) in northern Italy are given with a discussion of the results.In the Appendix, the technique of kriging is explained with reference to the estimation of the spatial distribution of the random rainfall field.
