| Abstract: | Using the method of tracking echo centroids, we have analysed the C-band digital weather radar data observed during the events of thirteen isolated severe storms and one squall line weather in 1987 and 1988, and presented the main results in forecast application, including forecast errors of cloud centroids under different weather conditions and for different intensity thresholds or different forecast time periods, and finally determined the suitable forecast parameters and corresponding forecast accuracy. On the knowledge, we will further introduce this program of tracking and warning storms into our digital radar analysing system for applications of the hail suppression and the flood forecast. |
