This project aims to quantify turbulent mixing in the ocean using ultra-high-resolution numerical modelling. Turbulent mixing is caused by internal waves which transport energy from the ocean boundaries into the interior, where they drive mixing of cold, deep water with warmer water above. This mixing is crucial to the ocean circulation which controls the storage of heat and carbon in the ocean, but is inadequately represented in current climate models. The anticipated outcome of the project is an enhanced, global-ocean model incorporating an accurate description of turbulent mixing. This should provide significant benefits to the Australian community by improving the accuracy of future climate predictions.

该项目旨在利用超高分辨率数值建模量化海洋中的湍流混合。湍流混合是由内波引起的，内波将能量从海洋边界输送到内部，在那里它们驱动冷水，深水与上面的温水混合。这种混合对于控制海洋中热量和碳储存的海洋环流至关重要，但在目前的气候模型中没有得到充分的体现。该项目的预期成果是一个增强的全球海洋模型，其中包括对湍流混合的准确描述。这将通过提高未来气候预测的准确性，为澳大利亚社会带来重大利益。
