             中文摘要:  利用常规资料和WRF模拟结果分析了2007年4月17日发生在广州白云机场附近的强对
流天气过程。结果表明,此次天气过程发生于高低层系统有利配置、南海季风涌活跃和低空
急流等低层系统加强使得华南地区具备充足水汽和不稳定条件的环境中。热力作用、地形和
锋面的抬升作用促使冰雹和飑线等强对流天气生成和发展。数值模式输出的局地强降水和雷

            Abstract:Based on meteorological observational data and WRF model products, the
 severe convective weather process at Baiyun airport on April 1
7, 2007 was analyzed. The results show that the strengthening of southwest monso
on and the establishment of the low level jet create the sufficient vapor and u
nstable condition in South China. The lifts of cold front and terrain promote the
 formation and development of convective weather. The precipitation of model out
puts and Radar echo  have a good instruction to the aviation security.
