This project aims to produce high quality data on how the Southern Westerly Winds (SWW) respond to largescale changes in climate boundary conditions over multiple glacial-interglacial cycles. Because the SWW are key drivers of Southern Hemisphere climate, Southern Ocean circulation and global carbon dioxide concentrations, it is important to understand how they respond to changes in boundary conditions. Uncertainty about how they do so limits attempts at accurate predictive climate modelling. This project will test conceptual models of SWW dynamics and provide essential boundary conditions for predictive climate models. The project intends to simultaneously build and support a research capacity and global network, and advance Australia’s knowledge and contribution in the area of global climate dynamics.

该项目旨在产生高质量的数据，以了解南西风（SWW）如何对多个冰川-间冰期循环中气候边界条件的大规模变化做出反应。由于西南风是南半球气候、南大洋环流和全球二氧化碳浓度的关键驱动因素，因此了解它们如何对边界条件的变化做出反应非常重要。他们如何做到这一点的不确定性限制了准确预测气候模型的尝试。该项目将测试SWW动力学的概念模型，并为预测气候模型提供必要的边界条件。该项目打算同时建立和支持研究能力和全球网络，并增进澳大利亚在全球气候动态领域的知识和贡献。
