Spanning ten billion scales from millimetre turbulence to global circulation

这个项目旨在解释海洋中对流的作用。对流是一个关键的气候过程，但它仍然是海洋中最鲜为人知的机制之一，在气候模型中得到了粗略的描述，导致对热量输送、气候变化、极地冰川消失和海平面上升的预测存在不确定性。使用独特的湍流解决方法和高性能计算，该项目将确定浮力驱动的对流在广泛的海洋环流中的全球作用，以及局部湍流对南极冰架融化速度的控制。这将有助于制定更好的气候模型，并使澳大利亚保持在海洋学和环境流体动力学的前沿。

This project aims to explain the role of convection in the ocean. Convection is a key climate process yet it remains one of the most poorly understood mechanisms in the ocean and is crudely represented in climate models, leading to uncertainties in predictions of heat transport, climate change, polar ice loss and sea level rise. Using a unique turbulence-resolving approach and high-performance computing, the project will determine both the global role of buoyancy-driven convection in the broad ocean circulation and the local turbulence controls on melting rates of Antarctic ice-shelves. This will contribute to the formulation of better climate models and keep Australia at the forefront of oceanography and environmental fluid dynamics.
