| Abstract: | 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. |
