Sensitivity and Change in the Global Ocean Overturning

将研究全球海洋深层翻转环流的动态以及这种环流如何适应不断增加的温室效应，以提高我们对海洋的概念性认识和气候模型的准确性。通过了解海洋如何应对不断变化的地表热量和淡水通量，特别是高纬度海洋快速变化的全球作用，我们的目标是帮助改进对气候响应时间和大气温室气体增加预期变暖的估计。气候系统的这两个重要特征是气候变化政策决定的基础。

The dynamics of the global, deep overturning circulation in the oceans and the way this adjusts to increasing greenhouse forcing will be examined in order to improve our conceptual knowledge of the oceans and the accuracy of climate models. By understanding how the ocean responds to changing surface heat and freshwater fluxes, and particularly the global role of rapid changes in high-latitude seas, we aim to help refine estimates of climate response times and the warming expected for a given increase in atmospheric greenhouse gases. These two important characteristics of the climate system underlie climate change policy decisions.
