| Abstract: | Using pressure-energy technique,some cases of heavy rain in Changjiang-Huaiheriver valley are investigated.It is found that the rain belts and heavy rain area are relat-ed to the dense pressure-energy belt.The triggering effect of pressure-energy on heavyrain is studied by using simplified divergence equation.The results show that inhomo-geneity of pressure-energy distribution can trigger the quick reinforcement of conver-gence in the low energy side of the belt.Furthermore,the rain area can be estimated bycomputing the pressure-energy distribution. |
