On the Temporal and Spatial Characteristics of Short-Term Urban-Scale Rainfall and Its Real-Time Prediction.

Abstract

This paper firstly presents the temporal and spatial characteristics of short-term urban-scale rainfall. The studies are based on measurements of rainfall made on a network of 12 gauges situated in the city of Lund, Sweden. Three-year series of one-minute rainfall records from each gauge are used for the analyses such as areal intensity-duration-frequency relationships. Secondly, a method for real-time prediction in time and space of urban-scale rainfall under the assumption that the rainfall process is governed by the stochastic convective-dispersion equation. The method is applied to the shortterm rainstorm prediction in the city of Lund.
