等流速线
速度分布图

The findings show that there exists overlap between macroscale convergence and warm advection if the degree of clock - wise turn dosen " t keep constant on both sides of zero doppler velocity contour about the near range of the observational site . the overlap produces vertical vapor transport and upward convergence movement favorable for formation and continuation of rain gush
结果表明：零速度带在测站近距离两侧的弯曲程度不一致是暖平流与大尺度辐合运动的迭加所造成，这一结构为暴雨产生和维持提供了有利的水汽垂直输送和辐合上升运动。
