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.

该项目旨在解释对流在海洋中的作用。对流是一个关键的气候过程，但它仍然是海洋中最缺乏了解的机制之一，并且在气候模型中粗略地表示，导致热传输，气候变化，极地冰损失和海平面上升预测的不确定性。该项目将利用独特的分辨率方法和高性能计算，确定浮力驱动的对流在广阔海洋环流中的全球作用以及对南极冰架融化速度的局部湍流控制。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。
