Abstract:

A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall derived from rain-gauge, radar and satellite observations. RAINPAK comprises four programs; STOVEL, THOR4DPT, THOR4D and THOR3D. This paper summarizes the results of the verification of the storm dynamics program STOVEL using rainfall records for the period 1980 - 1984 in the Hamilton-Wentworth Region, Ontario, Canada and the subsequent use of the program to analyze storm characteristics for the City of Toronto. The results of the analyses are presented as frequency distributions for the various attributes of the storms.
