摘要
为更好地对雷雨大风天气进行预报预警,利用地面常规气象资料和新一代多普勒天气雷达资料对2018年5月17日和8月6日贵州省铜仁市两次雷雨大风天气过程进行对比分析。分析结果表明:在雷雨大风发生前,常规气象要素有明显的增降变化,反射率因子、回波顶高、垂直液态水含量等雷达产品有较明显的变化特征,对雷雨大风天气有较好的指示意义,为提早及时的预报预警雷雨大风提供了可能。
In order to better forecast and warn about thunderstorms,comparative analysis of two thunderstorms occurred in Tongren City on May 17 and August 6,2018 was carried out based on regular ground weather data and the new-generation Doppler weather radar data.The analysis results showed that before the occurrence of thunderstorms,regular meteorological elements showed obvious changes,radar data such as reflectivity factor,echo top height and vertical liquid water content also showed obvious changes,which were good indicators of thunderstorm,and made it possible for timely forecast and warning of thunderstorms.
