| 摘 要： | 通过对1991－07－05T08－07－06－T20江淮流域的一次气旋发生发展过程的分析，讨论了在气旋发展的不同阶段高低层位涡场分布及垂直结构的演变特征，并从气旋发展过程中的凝结潜热释放着手，研究了高低层位涡场之间的联系。结果表明，潜热的释放将促使高层的高位涡向下传输，导致低层气旋加深发展，并进而讨论了江淮气旋发展的一种可能机制。

| Abstract: | The potential vorticity distribution at high and low levels and their evolution of vertical structure are discussed based on a case study of the cyclone appeared in Jiang-Huai Valley for the period of 08 July 5-20 July 6.In addition,the relation between the low and the high levels is also studied from the angle of releasing condensation latent heat in the process of the development of the cyclone.The results show that the releasing of condensation latent heat causes the downward transport of the high potential vorticity from high level and leads to the development of low level cyclone, which may be the possible mechanism of the development of Jiang-Huai cyclone. |
