Statistics about important feature parameters of the WSR-88D mesocyclone products is analyzed on the base of knowing the mesocyclone algorithm using the data of the last six years in Shanghai area. The basic features on mesoscale lifetime associated severe wind case are investigated. Then with the combination of severe wind records, the thresholds of adaptable parameters used mesocyclone algorithm in Shanghai are discussed and some adjustment schemes are suggested. Finally, a technical idea of forecasting local severe wind based on the mesocyclone products and other radar products are developed.
