摘　　要：根据常规气象观测资料、FY-4A卫星资料、风云地球资料及雷达资料等,分析了2022年7月28日娄底市北部一次冰雹天气。结果表明:此次冰雹天气过程发生在上干冷、下暖湿的较强不稳定环境,前期地面增温累积了热力不稳定能量,地面辐合线等触发了中小尺度系统的发生发展。强回波悬垂、三体散射、VIL异常高值等都是出现冰雹天气时的典型特征;在分析冰雹的常规气象资料的基础上,利用WBZ层高度和风云地球卫星等新型资料追踪冰雹天气发生的潜势与发展,对预判冰雹的强度和落区具有较好的指示作用。Based on conventional meteorological observation data,FY-4A satellite data,wind cloud earth data and radar data,analyzed a hail weather in northern Loudi on July 28,2022.The results showed that the hail weather process occurred in a strong unstable environment of dry and cold at the top and warm and wet at the bottom.The early ground warming accumulated thermal unstable energy,and the ground convergence line triggered the occurrence and development of small and medium-sized systems.Strong echo overhang,three-body scattering and VIL abnormal high value were typical characteristics of hail weather;On the basis of analyzing the conventional meteorological data of hail,using WBZ layer height and Fengyun Earth satellite and other new data to track the potential and development of hail weather,which has a good indication for predicting the intensity and falling area of hail.
