| 摘 要： | 分析了北半球不同时域Ｏ３层遥相关型的空间结构及其演变特征，探讨了太阳活动和极涡振荡对Ｏ３层遥相关型形成和演变的作用．结果发现：１．Ｏ３层对太阳活动响应具有显著的区域性，在不同季节里只存在一种Ｏ３层遥相关型与其相联系，随着季节的转换大气环流与太阳活动效应叠加将使Ｏ３层的响应区域及遥相关型的空间结构发生转移现象．２．极涡增强将导致Ｏ３层出现负异常，且在遥相关区域中Ｏ３含量的振幅变化最为显著．由于极涡的不对称性，各分区极涡强度对Ｏ３层遥相关型的影响存在着显著差异，表明极涡形变对Ｏ３层遥相关型的形成和演变具有重要作用．

| Abstract: | This paper analysed the space structure and the evolution feature of O3 layer teleconnection types in different time range in Northern Hemisphere, discussed the roles of solar activity and polar vortex oscillation to the formation and evolution of O3 layer teleconnection types.The results showed:(1) The response of O3 layer to solar activity has space inhomogeneous and notable regionallsm, in different season there is only one kind of O3 layer teleconnection space type which connected with it.With the season changing, the general circulation type superposed with solar activity effects will enable the space structures of O3 layer response region and the teleconnection type to occur transformation phenomenon.(2) Polar vortex enhancement will bring about the negative anomalg in O3 lager, and the amplitude change of O3 amount in teleconnection region is the most evident.Because of the asymmetry of polar vortex, the influence of polar vortex intensity in each region to O3 layer teleconnection type has notable difference, and this shows that deformation of polar vortex plays an important role in formation and evolution of O3 layer teleconnection type. |
