The Southern Ocean circulation is a major component of the earth’s climate system. Its behaviour depends strongly on the interactions of physical processes that are poorly understood and are not well represented in ocean models. This project will use laboratory experiments and fully-resolved flow simulations with appropriate scaling to examine the dynamics of key interactions between convection, mixing, wind-driven flow, eddies and large-scale currents, while translating the results to improve ocean models. The project will develop the fundamental physics of the deep overturning circulation, the Antarctic Circumpolar Current, response timescales and heat uptake in a warming world, and improve predictions of oceanic and climate change.

南大洋环流是地球气候系统的重要组成部分。它的行为在很大程度上取决于物理过程的相互作用，而这些物理过程的相互作用人们知之甚少，在海洋模型中也没有得到很好的体现。该项目将使用实验室实验和具有适当比例的完全解析的流动模拟来研究对流，混合，风力驱动的流动，涡流和大规模水流之间的关键相互作用的动态，同时将结果转化为改进海洋模型。该项目将发展深层翻转环流、南极绕极流、全球变暖中的反应时间尺度和热量吸收的基本物理学，并改进对海洋和气候变化的预测。
