0117346 OrsiInverse 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.

0117346将使用OrsiInverse建模技术来解决作为世界海洋环流实验综合阶段港口的南大洋的交通问题。盒式逆模式，适用于南极绕极流的亚南极锋和南极圈锋面之后的绕极水文剖面，以及多个WOCE和其他高质量的水文数据。该模式将明确地包括海气变换，以求出一组参考速度和与性质有关的有效昼夜速度，以及对这些通量的修正，这些通量与中性密度层中的性质守恒一致。以往用倒箱模式研究全球温盐环流受到南大洋内部缺乏控制剖面的严重限制，因此不能区分32S以南不同环流体制之间的经向交换。
