Collaborative Research: Southern Ocean Transports

0117346 OrsiInverse建模技术将用于解决南大洋的输运问题，作为世界海洋环流实验综合阶段的一个港口。箱形反演模型，应用于南极绕极流亚南极锋和南ACC锋之后的绕极水文剖面，沿着有多个WOCE和其他高质量水文数据。该模型将明确包括海气转换，以解决一组参考速度和属性相关的有效diapycnal速度，并纠正这些通量与中性密度层中的属性守恒。以往的逆箱模式对全球温盐环流的研究由于缺乏南大洋的控制断面而受到很大的限制，因此无法区分32 S以南地区不同环流体制之间的纬向交换。

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.
