澳大利亚的南部的海洋前面南方的喷气结构与新高度表 productAbsolute 在溪流坐标被学习从通报的动态地形学(ADT ) 。ADT 数据的精确性从一个二年的 subantarctic 前面实验与系在的数据被验证。ADT 与一致，这被表明在原处大小和俘获南极围绕天极的水流(ACC ) 的中央规模活动。ADT 表面的溪流坐标分析因地球自转而引起的流动发现 ACC 喷气展出大时间空间的可变性并且不对应于特别 streamfunction 价值。在围绕天极的范围 ACC，喷气显示地志的特征控制的一个短暂碎裂的模式。在 streamfunction 空间的喷气的 poleward 移动由一个 streamwise 关联方法揭示了显示带的动量的南方的流动的存在。如此的跨溪流的旋涡流动集中宽广 ACC baroclinic 流动进狭窄的喷气。在 thermohaline 领域里与最严重的实验模式(宝石) 的最近的发现结合了，学习在南部的海洋在前面，喷气和 streamfunction 之中澄清相互关系。

英文摘要：

The jet structure of the Southern Ocean front south of Australia is studied in stream-coordinate with a new altimeter product--Absolute Dynamic Topography （ADT） from AVISO. The accuracy of the ADT data is validated with the mooring data from a two-year subantarctic-front experiment. It is demonstrated that the ADT is consistent with in-situ measurements and captures the meso-scale activity of the Antarctic Circumpolar Current （ACC）. Stream-coordinate analysis of ADT surface geostrophic flows finds that ACC jets exhibit large spatio-temporal variability and do not correspond to particular streamfunction values. In the circumpolar scope ACC jets display a transient fragmented pattern controlled by topographic features. The poleward shift of jet in streamfunction space, as revealed by a streamwise correlation method, indicates the presence of meridional fluxes of zonal momentum. Such cross-stream eddy fluxes concentrate the broad ACC baroclinic flow into narrow jets. Combined with a recent discovery of gravest empirical mode （GEM） in the thermohaline fields, the study clarifies the interrelationship among front, jet and streamfunction in the Southern Ocean.
