摘要
用拉格朗日方法计算等熵面上空气质点和物质线的轨迹。分析指出１９９４年华南暴雨和夏季风异常有密切的关系，特别是东亚热带季风更是起着决定性的作用；用这种方法可以追踪水汽的源地及演变过程，分析气流对水汽的输送作用。
In this paper,the trajectory of particles and material line are calculated with the lagrangian method on an isentropic surface.The analysis shows that the heavy rain of South China is relative to Summer monsoon closely,in which the monsoon of East Asia plays an important role.The method can be used to track source area and evolution process of moisture and to analyse the effect of air current transport to moisture.
