| 摘 要： | 中尺度暴雨低涡主要位于800-700百帕等压面上,中心位于西南风和东北风急流之间,下方为反气旋环流,上方对流层高层亦为反气旋环流。低涡中心为下沉区,外围为上升带。暴雨低涡中心具有向着扰动场上的不稳定区移动的明显的倾向性。

| Abstract: | The mesoscale heavy rain vortex is mainly located on the 800-700 hPa isobaric surface with its center between the southwest and northeast jets and an anticyclonic circulation in both its lower part and the upper troposphere. The center of the vortex is a descending area and its rim an ascending band. It is found that the heavy rain vortex center has an obvious tendency to move toward the unstable area of the disturbanc field. |
