摘要利用涡旋解析模型研究了南印度洋-西太平洋(90°-145°E)涡旋通量与南极环极流喷流的关系。在这一区域,瞬态涡旋动量通量辐合发生在初级喷流核心的纬度,而涡旋浮力通量位于一个更广阔的区域,包括喷流和喷间最小值。在一个较小的扇区(120°-144°E),射流特别纬向性,对涡旋通量的时空分解进一步揭示,快速涡旋加速急流,在急流中心涡旋动量通量辐合最大,而缓慢涡旋往往在急流间最小值处使纬向流减速。转换欧拉平均值(TEM)诊断表明,涡动量贡献在所有模型深度加速喷流,而浮力通量贡献在~600 m以下深度减慢喷流。在喷流相对明确的海洋区域,存在喷流……
AbstractThe relationship between Antarctic Circumpolar Current jets and eddy fluxes in the Indo–western Pacific Southern Ocean (90°–145°E) is investigated using an eddy-resolving model. In this region, transient eddy momentum flux convergence occurs at the latitude of the primary jet core, whereas eddy buoyancy flux is located over a broader region that encompasses the jet and the interjet minimum. In a small sector (120°–144°E) where jets are especially zonal, a spatial and temporal decomposition of the eddy fluxes further reveals that fast eddies act to accelerate the jet with the maximum eddy momentum flux convergence at the jet center, while slow eddies tend to decelerate the zonal current at the interjet minimum. Transformed Eulerian mean (TEM) diagnostics reveals that the eddy momentum contribution accelerates the jets at all model depths, whereas the buoyancy flux contribution decelerates the jets at depths below ~600 m. In ocean sectors where the jets are relatively well defined, there exist jet-s...
