1480型多普勒天气雷达中尺度气旋识别模块设计

Design of Mesocyclone Identification Module for 1480 Doppler Radar

借鉴国内外中尺度气旋识别算法的研究成果特别是NSSL(National Severe Storm Laboratory)的中尺度气旋识别算法,结合多普勒天气雷达二次产品软件的特点,提出了改进的中尺度气旋识别算法,以动态链接库的形式,设计完成了中尺度气旋识别模块。对2002年5月27日安徽省北部地区的一次强对流天气过程的雷达资料进行了分析,并与北京敏视达(METSTAR)雷达有限公司Build 10.8软件系统生成的中尺度气旋产品进行了对比分析,结果表明该模块有比较好的识别能力,预警效果较好。

With research results concerned with mesocyclone for reference, especially the related content of MDA （Mesocyclone Detection Algorithm） from NSSL （National Severe Storm Laboratory ）, we present an improved MDA and the mesocyclone identification module in the Doppler Weather Radar Second Production software. Using the Doppler data of 27th May 2002 in Anhui Province ,we compare our results with the mesocyclone products produced by Build 10. 8 of METSTAR. The results show that our products have the same warning effect as Build 10, 8.
