Sea ice is a crucial part of the Australian and global climate systems, and the most sensitive indicator of the alarming climate changes in motion. This project aims to deliver a vital component in next-generation sea-ice models, by modelling ocean waves in the ice-covered ocean, and implementing it in the leading large-scale sea-ice model. The waves-in-ice model will be accurate for the range of possible wave–ice conditions, using understanding derived from state-of-the-art experimental measurements. Powerful mathematical approximation methods will be developed to generate model efficiency. The outcomes will create a new standard in sea-ice modelling, with significant benefits for sea-ice forecasting and climate studies.

海冰是澳大利亚和全球气候系统的重要组成部分，也是令人担忧的气候变化的最敏感指标。该项目旨在提供下一代海冰模型中的一个重要组成部分，方法是对冰盖海洋中的海浪进行建模，并在领先的大型海冰模型中加以实施。利用最先进的实验测量得出的理解，冰中海浪模型对于可能的海冰条件范围将是准确的。将开发强大的数学逼近方法来产生模型效率。这些成果将为海冰建模创造一个新的标准，对海冰预测和气候研究具有重大意义。
