利用闪电定位和雷达资料进行雷电临近预报方法研究
A STUDY OF LIGHTNING NOWCASTING METHOD USING LD-Ⅱ AND CINRAD-SA RADAR DATA
摘要
Abstract
Using LD-Ⅱ lightning detection system and CINRAD-SA Dopper Radar STI (Storm Tracking Information) data, the method of lightning nowcasting is studied. Comparing the lightning clusters detected by a lightning detection system with the storms identified by a Dopper radar, the result showed that lightning clusters are in the neighborhood of a storm. The lightning cluster and the storm move at similar direction and velocity, making it possible for a lightning cluster to match with one or more storms. The lightning clusters are extrapolated using the idea that every lightning cluster moves together with its matching storm and the storm's movement is obtained through the technology of Storm Cell Identification and Tracking (SCIT). With detected lightnings compared with those forecast for 2009, the critical success index(CSI) is found to be 63%(51%) and probability of detection(POD) about 87%(76%) for 30-min. (1-h) forecast. The study offers one new lightning nowcasting method that can be applied to routine operation.关键词
