| Abstract: |
| 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. |
