Collaborative Research: Southern Ocean Transport

[01:17618 . lumpkin1]作为世界海洋环流实验（WOCE）综合阶段的港口，将使用逆模拟技术来解析南大洋的输送。箱形逆模式，应用于南极环极流亚南极锋和南ACC锋的环极水文剖面，以及多个WOCE和其他高质量水文数据。该模型将明确地包括海气转换，以求解一组参考速度和与性质相关的有效底波速度，以及对这些通量的修正，这些通量与中性密度层的性质守恒一致。以往利用逆箱模式对全球温盐环流的研究由于缺乏南大洋内的控制剖面而受到严重限制，因此无法区分约32s以南地区不同环流体系的经向交换。

0117618 LumpkinInverse modeling techniques will be used to resolve the transports in the Southern Ocean as port of the synthesis phase of the World Ocean Circulation Experiment (WOCE). The box inverse model, applied to circumpolar hydrographic sections following the Subantarctic Front and southern ACC front of the Antarctic Circumpolar Current, along with multiple WOCE and other high-quality hydrographic data. The model will explicitly include air-sea transformations to solve for a set of reference velocities and property-dependent effective diapycnal velocities, and corrections to these fluxes consistent with property conservation in neutral density layers. Previous studies of the global thermohaline circulation by means of inverse box models have been severely restricted by their lack of controlling sections within the Southern Ocean, and therefore were not able to distinguish meridional exchanges among the different circulation regimes in the regions south of about 32 S.
