低层的

• The meso - scale model mm5 well reproduced the heavy rainfall process and the weather systems associated . using the output with high spatial and time resolution of the model , the development of the meso - scale vortex in the middle and lower troposphere is investigated and the structure feature and the possible physical mechanisms of it are presented
  利用mm5模式成功地模拟了这次梅雨锋暴雨过程，并利用具有高时空分辨的模拟结果针对这次暴雨过程的直接影响系统? ?对流层中低层的中尺度低涡进行诊断分析，揭示了这个中尺度低涡的结构特征和可能的形成机制。
