中文摘要: 对1996年夏季发生在副高西北侧和副高内部的皖东沿江地区两次强对流风暴过程进行了热力参数和动力学对比诊断,结果表明:两次过程的动力、热力学机制存在显著的差异;引入Q矢量分析后又发现:强雷暴及暴雨区与Q矢量辐合区有较好的对应关系;最后概述了这两类强风暴过程的0—12小时预报着眼点。
中文关键词: 夏季,强对流风暴,动力学诊断,短期预报
Abstract:The comparative diagnoses of thermodynamic parameters and dynamics show that obvious difference of dynamic and thermodynamic mechanics exists in the two severe convective storms developed in and to the northwest of subtropic high along the Changjiang River in East Anhui in the summer of 1996.It is found by conducting the Q vector analysis that the severe storms and heavy rain areas are in accordance with the convergence of Q vertor.The focus attention of short range (0-12 hours) prediction of the two kinds of severe storms is given.
