摘要
介绍了近年关于江南岭北春季连阴雨的湿度条件、等熵客观分析方法及其应用、华南双层锋区与高原东侧水平稳定层成因、南岭准静止锋附近加热场分布及其对锋面维持的影响、湿等熵位涡及其应用、孤立波理论在锋生及锋面维持研究中的应用等方面的进展情况．
In recent years,many problems, which are the humidity conditions,the method of objective isentropic analysis and its application,the formational mechnism of double-level frontal zones over South China and the horizontal stable-layer over the east-side of the Qinghai-Xizang Plateau,the heating distribution and its influence on frontal maintenance near by the quasi-stationary front over the Five Ridges, the wet isentropic potential vorticity and its application, the application of solitary wave theory to the study of the dynamic mechanism of frontogenesis and of frontal maintenance in the persistent rainy processes in spring over the areas between south of the Changjiang River and north of the Five Ridges, have been studied. The progress as mentioned above is introduced.
