利用次表层准等压RAFOS-float拉格朗日资料，描述了南极绕极流（ACC）110° ~ 45°W区域东南太平洋和斯科舍海区的大尺度中层环流和涡动扩散率。这些RAFOS浮标数据是在南大洋纵摇和等密度混合实验期间收集的。平均流，调整到一个共同的1400米的深度，显示出射流的存在，在时间平均意义上的速度为6厘米s-1的东南太平洋和13厘米s-1以上的斯科舍海。这些喷流似乎被锁定在斯科舍海的地形上，但除了通过海山链之外，在东南太平洋大多不受当地地形的限制。涡动动能（EKE）高于平均动能约50%的采样域中的任何地方。EKE的幅度急剧增加（2倍或更多），因为电流穿过英雄和…
AbstractThe large-scale middepth circulation and eddy diffusivities in the southeast Pacific Ocean and Scotia Sea sectors between 110° and 45°W of the Antarctic Circumpolar Current (ACC) are described based on a subsurface quasi-isobaric RAFOS-float-based Lagrangian dataset. These RAFOS float data were collected during the Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean (DIMES). The mean flow, adjusted to a common 1400-m depth, shows the presence of jets in the time-averaged sense with speeds of 6 cm s−1 in the southeast Pacific Ocean and upward of 13 cm s−1 in the Scotia Sea. These jets appear to be locked to topography in the Scotia Sea but, aside from negotiating a seamount chain, are mostly free of local topographic constraints in the southeast Pacific Ocean. The eddy kinetic energy (EKE) is higher than the mean kinetic energy everywhere in the sampled domain by about 50%. The magnitude of the EKE increases drastically (by a factor of 2 or more) as the current crosses over the Hero and...
