泰州市一次强对流天气过程分析

Analysis of a Severe Convective Weather Process in Taizhou

摘要: 本文利用常规气象观测资料、雷达回波资料和垂直风廓线资料等，分析了2023年6月10日泰州市的一次强对流天气过程。结果表明，此次强对流过程发生在东北冷涡背景下，槽后西北急流携带的干冷空气叠加在低空暖湿气流之上，形成“上干冷，下暖湿”的层结条件，热力和动力条件好，在积聚一定的能量之后，由地面辐合线抬升触发，造成泰州市的大风、短时强降水、局地冰雹等天气。在监测预报时，综合分析雷达回波资料和垂直风廓线资料等多源观测资料，对强对流天气的预报有一定的指示意义。

Abstract: This article analyzes a severe convective weather process in Taizhou on June 10, 2023, using con-ventional meteorological observation data, radar echo data, and vertical wind profile data. The results indicate that this severe convective process occurred under the background of a northeast cold vortex, with dry and cold air carried by the northwest jet stream behind the trough superim-posed on the low-level warm and humid airflow, forming a layered condition of “dry and cold above, warm and humid below”. The thermal and dynamic conditions were good, and after accumulating a certain amount of energy, they were triggered by the elevation of the ground convergence line, causing strong winds, short-term heavy rainfall, local hail and other weather conditions in Taizhou. When monitoring and forecasting, the comprehensive analysis of multi-source observation data such as radar echo data and vertical wind profile data has certain indicative significance for pre-dicting severe convective weather.
