Abstract
To define the spatial and temporal characteristics of rainstorms, 20 time series of weather radar images over northwestern Europe were analysed. The velocity of rainfall events and the direction of movement were determined for 1632 radar images using the cross-correlation technique. A technique was developed to discriminate single rainstorms within a radar image. After calculating the area and perimeter of these rainstorms, different methods to define the dimensions of rainstorms were proposed. Statistical calculations revealed that the dimensions of rainstorms in the direction of the rainfall movement were significantly different from the dimensions in the direction perpendicular to the movement. Rainstorms are composed of several rain cells which are clustered together. In order to describe the occurrence of cell clusters, a new technique was used for localizing cluster centres within a rainstorm. The positions of the cluster centres along and across the rainfall movement follow a Poisson distribution.
