Zhang et al interpret the mixed-layer energy budget in models as showing that "ocean dynamics play a central role in the AMO." Here, we show that their diagnostics cannot reveal the causes of the Atlantic Multidecadal Oscillation (AMO) and that their results can be explained with minimal ocean influence. Hence, we reaffirm our findings that the AMO in models can be understood primarily as the upper-ocean thermal response to stochastic atmospheric forcing.
张等人将混合层能量收支模式解释为表明“海洋动力在北大西洋涛动（AMO）中起着核心作用”。在这里，我们表明，他们的诊断方法无法揭示 AMO 的原因，而且可以用最小的海洋影响来解释他们的结果。因此，我们重申我们的发现，即模式中的 AMO 主要可以理解为上混合层对随机大气强迫的热响应。
