摘要利用2005-10年同化资料的南大洋状态估计（SOSE），研究了南极绕极流（ACC）上层海洋热收支的空间结构。ACC环极综合收支表明，0.27 PW的海洋从大气中获得的热量和0.38 PW的地转热输送散度获得的热量被−0.58 PW的埃克曼热输送散度冷却和−0.09 PW的垂直热输送散度平衡。然而，这种环极综合平衡掩盖了热量收支的重要纬向变化。海-气热通量显示出一种纬向非对称的模式，在印度洋和大西洋部门的ACC和太平洋部门的海洋热量损失的海洋热量增益。在大西洋和印度洋部门的ACC，表面海洋热量增益主要是平衡的向赤道Ekman热量输送，冷却上层海洋的发散。在太平洋区，由于Ekman热量的发散，表层海洋热损失和冷却...
AbstractThe spatial structure of the upper ocean heat budget in the Antarctic Circumpolar Current (ACC) is investigated using the ⅙°, data-assimilating Southern Ocean State Estimate (SOSE) for 2005–10. The ACC circumpolar integrated budget shows that 0.27 PW of ocean heat gain from the atmosphere and 0.38 PW heat gain from divergence of geostrophic heat transport are balanced by −0.58 PW cooling by divergence of Ekman heat transport and −0.09 PW divergence of vertical heat transport. However, this circumpolar integrated balance obscures important zonal variations in the heat budget. The air–sea heat flux shows a zonally asymmetric pattern of ocean heat gain in the Indian and Atlantic sectors and ocean heat loss in the Pacific sector of the ACC. In the Atlantic and Indian sectors of the ACC, the surface ocean heat gain is primarily balanced by divergence of equatorward Ekman heat transport that cools the upper ocean. In the Pacific sector, surface ocean heat loss and cooling due to divergence of Ekman heat...
