| 摘 要： | 利用耗散结构理论的相关知识,从非平衡态理论的熵密度平衡方程出发,计算了2004年6月23日发生在湖南西部和北部地区暴雨发生前24h至暴雨结束前12h每隔6h对流层中低层的熵变场。通过对各个不同时刻的熵变场的分析与比较,讨论了熵场变化与暴雨区域、强度及其演变之间的关系,为暴雨强度和落区预报提供了参考指标。 |

| Abstract: | In this paper,the dissipative structure theory and the entropy density balance equation of non-equilibrium theory are used to calculate the entropy change associated with a rainstorm in the west and north of Hunan province on June 23,2004.The entropy change is calculated at the middle and lower levels of the tropopause at a 6 h interval from twelve hours before and after the rainstorm.Besides,through the analysis and comparison of entropy change in different time,the relationships of entropy change with the... |
