The results showed that there was a mesoscale vortex tube along the mesoscale shear line on the middle low troposphere, and its altitude varied in a wave shape.

发现沿切变线走向有一条中尺度涡管，位于对流层中低层，高度呈波状起伏。

The rain storm activities relate to the mesosynoptic systems such as the mesoscale shear line, the mesoscale convergence line and the mesoscale convergence center.

雨团活动与中尺度切交线、辐合中心、辐合线等中尺度天气系统相配合。

The heavy rainfall is dominated by a mesoscale warm shear line, having a closed relationship with a mesoscale system composed by mesoscale shear line, thunderstorm high and mesoscale vortex;

这次强降水与中尺度切变线、雷暴高压和中尺度气旋等中尺度系统关系密切，为一次中尺度暖式切变线暴雨过程；
