McCartney 9617946 The secular variability in various components of the meridional overturning circulation of the North Atlantic and the linkages between these components and the variability in the overlying atmosphere will be examined by using historical oceanographic data. The work will address the question of whether the decadal trends in warm water transformation, which co-vary with the low frequency North Atlantic Oscillation, represent an oceanic response that is passive, active or a coupled interaction. This proposal is a contribution to the CLImate VARiability and predictability (CLIVAR) program.

北大西洋经向翻转环流各分量的长期变率，以及这些分量与上覆大气变率之间的联系，将利用历史海洋学资料加以研究。这项工作将解决与低频北大西洋涛动共同变化的暖水转变的年代际趋势是否代表一种被动、主动或耦合相互作用的海洋响应的问题。该提案是对气候变率和可预测性（CLIVAR）计划的贡献。
