冷空气与南海低压相互作用两次过程的对比分析

Comparative Analysis of Two Interaction Processes of Cold Air and Nanhai Low Pressure

通过对２０００年９月７～９日、１０月１２～２３日２次冷空气与南海低压相互作用过程的天气过程、环流形势、卫星云图、气象要素等的对比分析，找出２次过程影响系统及演变过程的异同点，得出２次影响系统相似，但由于系统的配置和强度不同，造成的天气过程也不同的结论。

Through the comparative analysis of weather process, circulation situation, satellite could picture and meteorological factors, etc. during the two interactions of cold air and Nanhai low pressure occurred on Sep. 7 - 9 and Oct. 12 - 23, 2000, the similarities and differences of the influencing system of the two processes and that of the evolution process are shown. Based on this, this paper concluded that two similar influencing systems would result in different weather processes due to different configuration and strength of the systems.
