| 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 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。 |
| 4. | The strong convergence areas , which are coincide to the big rain belt , mostly lie in the planetary - scale water vapor transport . iii
夏季垂直积分的水汽输送通量强辐合区大多位于行星尺度水汽输送大值带中，和降水大值区之间有很好的对应关系。 |
| 5. | When the baroclinicity of southwest vortex had not been built and where cold front existed , the rain belt may lie in anywhere of the left of southwest low level jet
在西南涡斜压性未建立之前以及冷锋附近，暴雨区可位于低层西南风急流左侧的任何位置。 |
| 6. | But when the baroclinicity of low level vortex was strengthened and when warm air came into being , all the rain belts lay in the left and the front of southeast low level jet
当低涡的斜压性加大，出现暖空气的作用时，暴雨区均出现于西南风急流的左前方。 |
| 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。 |
| 8. | We classified flood and drought years of summer and autumn , it is pointed out in the paper that there are circulation anomaly in 500mb height field before flood or drought years . we also find out that there are intimated relation between autumn floods and droughts of zhejiang province and the macro - scale rain belt . the meteorological elements emergence abnormal features in summer before flood and drought years . we make out predictor to predicate summer precipation
论文结合三种排序方法划分了夏秋旱涝年，研究表明，夏季、秋季旱涝年前期冬季和夏季500hpa高度场环流有明显的异常特征，夏秋旱涝与我国夏秋大尺度天气气候异常有密切的关系，旱涝前期我国气象要素场有明显的异常特征。制作了浙江省夏季旱、涝预报工具。 |
| 9. | The above circul ation structure cause that rain belt tend to north in summer in china , rainfall of the yellow river valley and north china become more , but rainfall of south to the yellow river and yangtze river valley become less , meanwhile temperature of northwest and central region become high , but temperature of south department foreland become low
这样的高低空的环流配置造成我国夏季雨带位置偏北，多雨区在黄河流域及华北地区，而黄河以南、长江流域降水偏少，同时我国西北和中部地区气温偏高，南部沿海地区的气温偏低。 |
