摘　　要：文章利用区域自动气象站监测资料和都匀雷达探测资料,在应用雷达探测软件ROSE 2.0产品的基础上,分析黔南布依族苗族自治州2022-04-24傍晚到夜间的一次强对流天气过程特征。结果表明,ROSE 2.0产品能识别出冰雹和大风;雷达探测的小时降水量偏弱,主要是受Z-I关系及黔南西面螺丝壳山脉遮挡影响;ROSE 2.0产品报警功能对小冰雹有一定的指示意义。本次强对流天气过程的分析对促进雷达产品在黔南的广泛应用有积极作用,ROSE 2.0产品识别的特征量可为短时强降水、冰雹、大风等灾害性天气的提前预警提供参考。This paper analyzes the characteristics of a severe convective weather process from afternoon to night in Qiannan Buyi and Miao Autonomous Prefecture on April 24,2022,using monitoring data from regional automatic meteorological stations and radar detection data from Duyun,based on the application of radar detection software ROSE 2.0 product.The results indicate that ROSE 2.0 product can recognize hail and storm winds;the hourly precipitation detected by radar is relatively weak,mainly due to the Z-I relationship and the obstruction of the screw shell mountain range in the west of Qiannan;the ROSE 2.0 product alarm function has a certain indicative significance for small hail.The analysis of this severe convective weather process has a positive effect on promoting the widespread application of radar products in Qiannan.The feature quantities identified by ROSE 2.0 product can provide a reference for early warning of catastrophic weather such as short-term heavy rainfall,hail,and strong winds.
