dc.description.abstractThe relationship between Atlantic multi-decadal oscillation (AMO) and Atlantic meridional overturning circulation (AMOC) is examined with respect to two (inter- and multi-decadal) different timescales using a long-term unforced simulation of an earth system model of intermediate complexity. In the inter-decadal timescale, the AMO and the AMOC establish a self-sustaining oscillatory mode; the AMOC induces the positive AMO through meridional heat transport (MHT), but with the time delay of approximately 7 years as the AMOC anomalies propagate southward over time within the Atlantic basin. After then, the AMO reduces the density in the main sinking region and brings the negative phase of the AMOC, which results in the rest half of the cycle. On the other hand, in the multi-decadal timescale, the AMO and the AMOC are almost in phase because the AMOC is spatially stationary, resulting in a pan-Atlantic surface warming. In addition, the Arctic-originated density fluctuations are required for the multi-decadal AMOC to switch its phase. The results obtained in this study suggest that timescale dependency should be considered when investigating the AMOC-AMO relationship.-
