摘　　要：选择常规气象资料、NCEP全球分析资料等资料,分析X波段双偏振相控阵雷达在2021年7月19—22日许昌持续区域性大暴雨和2021年7月16日许昌局地短时强降水2次过程中的应用。结果表明:相控阵雷达体扫垂直精细化能力,大幅度提升了重要雷达产品的准确性,包括VIL、降水估计、冰雹指数以及风暴识别预警等。This paper selects conventional meteorological data, NCEP global analysis data and other data, mainly analyzes the application of X-band dual polarized phased array radar in the two processes of continuous regional heavy rain in Xuchang on July 19-22,2021 and short-term heavy rain in Xuchang on July 16, 2021. The results show that the vertical refinement capability of phased array radar has greatly improved the accuracy of important radar products, including VIL,precipitation estimation, hail index and storm identification and early warning.
