摘要 为了更好地开展江西夏季冰雹天气的监测预警工作,文章使用天气图、闪电数据、雷达拼图等资料,采用天气学、雷达气象学等原理及分析方法,对2022年78月江西婺源和石城两次超级单体冰雹回波进行分析,结果表明:婺源冰雹和石城冰雹天气形势有所不同,但都处在弱垂直风切变环境下;婺源冰雹属于微型超级单体,组合反射率强度达55~60 dBZ,维持时间10 min左右;石城冰雹属于经典超级单体,组合反射率可达60~70 dBZ,维持时间至少30 min;婺源、石城两地冰雹实际发生地点与闪电密集区均相对应;两地最强闪电都超过50次/10 min,并集中于16:0017:00。希望分析结果能为江西盛夏季节弱垂直风环境下冰雹回波的识别与监测提供依据。

Abstract:In order to better carry out the monitoring and early warning of hail weather in summer in Jiangxi,weather maps,lightning data,radar puzzles and other materials were used.The principles and analysis methods of meteorology and radar meteorology were adopted to analyze the echoes of two super unit hail events in Wuyuan and Shicheng,Jiangxi from July to August 2022.The results showed that the hail weather patterns in Wuyuan and Shicheng were different,but both were in weak vertical wind shear environments.Wuyuan hail belongs to micro super monomers,with a combined reflectivity intensity of 55-60 dBZ and a maintenance time of about 10 minutes.Shicheng hail belongs to the classic supercell,with a combined reflectivity of 60-70 dBZ and a maintenance time of at least 30 minutes.The actual location of hail occurrence in Wuyuan and Shicheng corresponds to the lightning intensive area.The strongest lightning strikes in both places exceed 50 times per 10 minutes and are concentrated between 16:00 and 17:00.It is hoped that the analysis results can provide a basis for identifying and monitoring hail echoes in weak vertical wind environments during the summer season in Jiangxi.
