The Southern Ocean is critical to the global climate system in general, and Australian climate in particular. However, the Southern Ocean is poorly understood, poorly observed and poorly modelled by global climate models. The response of the Southern Ocean to increases in wind forcing (due to the ozone hole and global warming) will be examined. Climate impacts such as Australian rainfall trends, potential instability of the West Antarctic Ice Sheet and changes to the global overturning circulation will be quantified. Understanding these impacts will help to manage Australia's water resources and to predict the future Southern Ocean circulation.

南大洋对全球气候系统至关重要，特别是澳大利亚的气候。然而，人们对南大洋的了解很少，观测也很少，全球气候模型对南大洋的模拟也很差。将审查南大洋对风力增加（由于臭氧空洞和全球变暖）的反应。气候影响，如澳大利亚的降雨趋势，南极西部冰盖的潜在不稳定性和全球翻转环流的变化将被量化。了解这些影响将有助于管理澳大利亚的水资源，并预测未来的南大洋环流。
