Summary

Observations of convective precipitation catch at ground level, by means of dense raingage networks, permit obtaining sets of detailed isohyetal maps describing the rainfields in time and space. Analyses of these isohyetal maps for a number of storm events indicates that individual storm cell precipitation intensity patterns vary by a process that can be approximated by means of a group of random functions. The paper discusses the nature of these functions, their evaluation, and the manner whereby they are combined into a complete scalar field model of the storm. This model has been implemented by means of a computer program that can be interfaced directly with distributed catchment models.
