The Southern Ocean Meridional Overturning Circulation: New observations of vertical mixing

南大洋和南极绕极流（ACC）在澳大利亚和全球气候中发挥着重要作用。 然而，我们对它们将如何受到全球变暖的影响知之甚少。 新的速度观测将告诉我们，垂直混合，有助于纬向翻转环流，ACC强度，如何随季节和每年的变化。 这些观测还将使我们更好地了解驱动这些变化的海洋和大气过程。 这些新的信息将使气候模型能够更好地受到约束，从而能够更准确地预测澳大利亚和全球气候的变化。

The Southern Ocean and Antarctic Circumpolar Current (ACC) play profound roles in Australian and global climate. However, we know little about how they will be affected by global warming. New velocity observations will tell us how the vertical mixing that contributes to the meridional overturning circulation, and ACC strength, change with the seasons and from year to year. The observations will also give us a better understanding of the oceanic and atmospheric processes that drive these changes. This new information will allow climate models to be better constrained so they can more accurately predict changes to Australian and global climate.
