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.

麦卡特尼9617946北大西洋的子午倾覆循环的各个组成部分的世俗变异性以及这些成分之间的联系与上覆气氛的可变性将通过历史海洋学数据来检查。这项工作将解决一个问题，即与低频北大西洋振荡共同变化的温水转化中的十年趋势是被动，主动或耦合相互作用的海洋反应。该建议是对气候可变性和可预测性（CLIVAR）计划的贡献。
