| 1. | 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。 |
| 2. | 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。 |
| 3. | In a word , convective instability strong baxoclinicity barotropic advection of potential vorticity and latent heat release are factors which activize this explosive development of cyclone
总之，对流不稳定、强斜压性和正压位涡平流、潜热释放是本次气旋发展的启动因子。 |
| 4. | The baroclinic component of the real atmospheric flow fields played a dominant role during the torrential rain . with the development of the rainstorm , the barotropic component of the real atmospheric flow fields decreased , along with the baroclinic component increasing
暴雨前后，实际大气流场的斜压性一直占主导地位，并且随着暴雨的发展，实际大气流场的正压性减弱而斜压性进一步增强。 |
| 5. | The numerical simulation with complete forcing produces the main characteristics of yellow and east china seas circulation in summer . baroclinic effect plays a important role on yellow seas circulation that yellow seas cold water mass induces a anticlockwise circulation . tide also strengthens it
夏季黄海的环流结构体现了较强的斜压性，主要以密度流为主，黄海冷水团在黄海中部诱导了一个气旋式环流，潮汐作用亦对这一环流有贡献。 |
| 6. | In the upper troposphere , there is no intact asian active center . the troposphere structure of summertime ao is implicated with the horizontal heterogeneity of air temperature throughout the whole troposphere with its center over asian continent , which results in the zonal asymmetry and baroclinic structure of the summertime ao ( especially its asian center ) . on the contrary , the correlation between wintertime ao and sea - land thermal contrast confines in the lower troposphere , hence its zonal asymmetry and baroclinity in the lower level
夏季北极涛动的这种结构与对流层整层的温度水平分布不均匀性有密切联系，且这种温度分布差异主要体现在亚洲大陆，因而也就使北极涛动的中纬度亚洲中心呈现出比同纬度带其它区域更为明显的纬向非对称性和斜压性；而冬季北极涛动受下垫面海陆分布差异影响，其纬向非对称型和斜压性质主要出现在对流层中低层，在对流层高层表现出很强的环形模态和正压结构。 |
| 7. | The analysis of dry pv shows that the high pv dominate the area of typhoon , the higher is the center value of pv , the stronger is the typhoon . lt is also shown that the most important reason resulting in rainstorm is the cold air ( high pv ) which spreads to south from the upper troposphere or lower stratosphere and transports into the warm air . the joining situation of upper and lower pv area make vortex develop . pv transpotation reduces static stability , which increases the releasing of instability energy and makes rainstorm amplify
对干位涡的分析表明：台风或台风环流区为高值位涡区，台风越强，位涡中心值越大；对流层上部或平流层下部冷空气(高位涡)的扩散南下与暖湿气流的交汇是造成特大暴雨的重要原因，因为上游斜压性的发展使对流层顶发生折叠，平流层与对流层相互作用增强，上下位涡区相接的形势使低层涡旋发展，上升运动加强，位涡的下传有效地降低了静力稳定度，有利于位势不稳定能量的释放，使得暴雨增幅。 |
| 8. | In contrast , the out - of - phase vacillation in summertime ao covers the arctic region and mid - latitude asian continent . though the summertime ao exists on intraseasonal as well as interannual time scale , its asian active center abates on the intraseasonal pattern , thus awarding it more conspicuous zonal symmetric structure . interannually , summertime ao exhibits the zonal asymmetric and baroclinic features , and its seesaw mode is significant only in the lower troposphere
在年际时间尺度上，夏季北极涛动表现出比冬季北极涛动更强的纬向非对称性和对流层高、低层位相不一致的斜压性，其极地中心和亚洲中心的反位相涛动关系在对流层低层比较显著，向上逐渐减弱，到对流层高层不能表现明显的亚洲中心。 |
| 9. | In the second part of the paper , with employing the game reanalysis data and on the basis of the theories of the baroclinic vorticity development , this paper inferred from the dynamic analysis that the horizontal vorticity can represent the baroclinic intensity of the large - scale atmosphere , and the conversion of the horizontal vorticity converting into the vertical vorticity is actually the phenomenon that the horizontal vorticity flux of the summer monsoon owning the striking longitudinal - direction vertical structure and the strong baroclinicity , influence on the horizontal movement of the atmosphere
在第二部分，基于第一部分的结果，本文在斜压涡度发展理论的基础上，用在我国季风区具有更高准确性的game再分析资料，讨论分析了能代表大尺度大气斜压性强度的水平涡度在向垂直涡度转化的情况，说明了此转化就是具有明显经向垂直结构特征和强斜压性的夏季风环流圈将其经向垂直剖面上的涡旋通量强迫于水平运动的现象。 |
| 10. | With the development of the storm , the barotropic component of the mesoscale flow field was decreasing and the baroclinic component was reinforced . on the contrary , the barotropic component of the subsynoptic scale flow fields was reinforced and the baroclinic component was decreasing . the baroclinic kinetic energy played a key role in the process of the rainstorm .
暴雨前后，次天气尺度与中尺度流场的斜压性都是占主导地位，随着暴雨的发展，中尺度流场的正压性减弱而斜压性进一步增强，而次天气尺度流场的正压性增强而斜压性减弱。 |
