The question as to whether lateral variation in global ocean buoyancy resulting from low solar radiation near the poles and higher temperatures in the tropical regions (known as horizontal convection) is a driver for global ocean currents is critical to our understanding of this complex and delicate system that maintains Earth's temperate climate. This question hinges on the relationship between heat transport and strength of buoyancy forcing towards global scales; this project proposes a landmark experimental effort supported by detailed simulations to probe the ultimate regime of heat transport in horizontal convection. The project is expected to inform the direction of future ocean and climate modelling efforts to the benefit of humanity.

极地附近的低太阳辐射和热带地区较高的温度(称为水平对流)造成的全球海洋浮力的横向变化是否是全球洋流的驱动因素，这一问题对于我们理解这个维持地球温带气候的复杂而微妙的系统至关重要。这个问题取决于热量传输和浮力强度之间的关系；这个项目提出了一项具有里程碑意义的实验工作，并通过详细的模拟来探索水平对流中热量传输的最终机制。该项目预计将为未来造福人类的海洋和气候建模工作指明方向。
