摘要
本文利用绍兴X波段相控阵阵列天气雷达对2023年7月10日的1次冰雹大风过程进行探测,结合绍兴S波段雷达资料、天气形势资料与自动站资料分析,得出以下结论:(1)此次过程是在梅雨锋背景下冷暖平流交汇形成的1次强对流天气过程。(2)相控阵阵列天气雷达1 min时间间隔的探测精准捕捉到冰雹风暴的发展全过程及其精细的三维动力、热力结构,揭示了冰雹形成原因。(3)相控阵阵列天气雷达成功探测到阵风锋过程及其在移动过程中触发生成的新对流单体。(4)由于相控阵雷达的高时空分辨率,风暴识别提前了20 min识别冰雹,并进行告警。
An X-band phased array weather radar in Shaoxing was used to detect a hail gale on July 10,2023 based on the analysis of S-band radar data,synoptic data and automatic weather station data in Shaoxing,the following conclusions are drawn:(1)This process was a strong convective weather process formed by the convergence of cold and warm advection under the background of Meiyu Front.(2)The whole process of hail storm development and its fine 3D dynamic and thermodynamic structure were accurately captured by phased array weather radar at 1 min interval,and the reason of hail formation was revealed.(3)The phased array weather radar successfully detected the gust front process and the new convective cells generated during the process of its movement.(4)Because of the high spatial-temporal resolution of phased array radar,the hail was identified 20 min ahead of time and warned.
