| 1. | The southern spread of low - layer inertia - gravity wave was benefited for coming into being of excessive strip rain belt
低层向南传播的重力惯性波有利于多条雨带的形成。 |
| 2. | It was benefited for southern spread of inertia - gravity wave in the symmetric instability region of the south of the high layer of rain belt
高层雨带南部的对称不稳定区，有利于重力惯性波的向南传播。 |
| 3. | The northern spread of high - layer inertia - gravity wave could result in the development and northern moving of low - layer vortex and precipitation
高层向北传播的重力惯性波可导致低层的涡旋和降水发展和北移。 |
| 4. | The north of the low - layer of rain belt was mainly convection instability . so the northern inertia - gravity wave was not easy to develop and to spread
雨区的北部低层以对流不稳定为主，因此向北的重力惯性波不易发展传播。 |
| 5. | So we found that convection instability could inspire inertia - gravity wave . symmetry instability was benefited for spread of inertia - gravity wave and further influenced the development and motion of precipitation
可见对流不稳定可激发重力惯性波，对称不稳定可使重力惯性波发展与传播，从而影响到降水的发展与活动。 |
| 6. | In the metaphase of precipitation , the high - layer inertia - gravity wave presented indirect circulation posture circling the center of low - layer vortex . . at this time precipitation became stronger and moved towards the east
在降水的中期，高层的重力惯性波出现围绕低层涡旋中心逆时针旋转的形势，此时降水开始加大并东移。 |
| 7. | We analyzed the meso - scale disturbance field and found that the development and spread of inertia - gravity wave had a close relationship with the development and spread of the rain belt . at the initial stages of precipitation , convection instability was strong in the low level above rain region . convection instability could inspire inertia - gravity wave
对中尺度扰动场分析发现重力惯性波的发展和传播与雨带的发展与传播有密切的联系：在降水初期，雨区上空低层的对流不稳定较强，对流不稳定可激发出重力惯性波。 |
