| 摘 要： | 通过对两次大范围强雷电天气的分析得出:冷锋切变线南压和副热带高压西伸都能造成广西大范围强雷电天气,其中,2007年4月17日过程具有干冷空气的中层入侵,大气雷电性不稳定非常明显,而2004年7月21日过程主要是由于东南气流加强和地形的影响,造成气流辐合抬升。

| Abstract: | Basing on the analysis of two strong lightning storms in Guangxi,the influencing weather systems were discussed.It shows that the southward shear line of cold front and subtropical high westward extension can cause a large scale strong lightning storms.The storm process of April 17,2007 accompanies dry cold air invasion with obvious atmospheric lightning instability.The storm process of Junly 21,2004 was influenced by the convergence and uplift of airflow caused by southeast airflow strengthen and topography. |
