The estimation and distribution of storm movement and storm structure, using a correlation analysis technique and rain-gauge data
Abstract
A method of estimating the speed and direction of movement of storm rainfall patterns is described. The method takes data from a network of continuously recording rain-gauges. An analysis is then made of the cross-correlations between all pairs of rain-gauges of the network for different time lags. As well as providing an estimate of storm motion the method gives an indication of temporal and spatial structure of the storm. Data from two small rainfall networks are used to demonstrate the method. One is at Cardington; the other at Winchcombe, England. In total, 219 storms are analysed by the method and frequency distributions of storm motion and storm structure are presented for this sample of storms. The relationship between storm and motion and 700-mbar wind motion is also studied.
