| 摘 要： | 以1983年4月28日影响江淮地区的冷锋天气过程为例，讨论了高空急流加速与锋生函数之间的关系。计算结果表明了在这次冷锋天气过程的前期，高空急流加速对对流层中层锋生具有重要贡献。而在这次冷锋天气过程的后期，低层锋生可能是由斜压波从基流中获得发展的能量而诱使低层锋生。

| Abstract: | Using the data of a cold front event which affected Changjiang Huaihe area on 27-28 April 1983,the relationship between the acceleration of upper jet stream and middle-lower frontogenetical function is discussed.The results explain that in the earlier periodof this case,the acceleration is an important contribution to the middle layer frontogene-sis but in the latter period baroclinic wave with energy from the basic flow would lead tothe lower layer frontogenesis. |
