摘要
本文分析了三个产生强对流天气冷涡过程的卫星云图.冷涡云系的结构可归纳为单纯的冷涡结构和具有锢囚气旋结构两类.利用诊断分析对冷涡云系中各个组成部分,即涡旋云区、不稳定云区、正涡度平流云区、冷涡云区及暖锋云区与有关物理量的配置关系进行了讨论.
In this paper, the satellite images of three cases of cold vortices, which caused the severe convective weathers, are studied. The structure of cold vortex cloud system is catalogued by two types, the simple vortex structure and the occluded cyclone structure. The physical interpretation of various constituent parts of the cold vortex cloud system, i.e. the eddy cloud area, the instable cloud area, the positive vorticity advection cloud area, the cold front cloud area and the warm front cloud area, are discussed with diagnostic data.
