中文摘要: 在深入了解WSR-88D多普勒天气雷达产品——中气旋算法的基础上,对上海地区近6年间中气旋产品的几个重要特征参数进行了统计研究,并结合局地强风的个例分析,总结了上海及周边地区中气旋发生发展过程中各阶段的基本特征。最后综合参考雷达其他相关产品,提出利用中气旋产品进行强风预报的思路,以期为准确预报局地强风天气提供一些参考信息。

Abstract: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.
