Abstract
The objective of this chapter is to present an investigation of the robustness of an algorithm for storm direction and speed. The algorithm is used in a utility called "Rainpak" in PCSWMM. In this chapter we first present an approach for estimating the mean speed and direction of a multi-cellular rainstorm using rate-of-rain gages. The code for spatial analysis of storms and their cells is described. Then we present a Monte Carlo analysis of rain storms observed in Toronto and Hamilton, Ontario, in which we demonstrate the robustness of the analysis with respect to observational uncertainty.
