| Summary: | <!--!introduction!--> The North Atlantic sea surface temperature multidecadal oscillation, or AMO, has a substantial impact on both the global and local climate. The authors suggest a delayed oscillator model of interdecadal sea-air coupling to describe the underlying physical principles of AMO. On the basis of the impact of cumulative atmospheric forcing on ocean circulation, they also develop new AMOC indicators and shed light on the AMO's dynamics. To explain the remote impacts of AMO, the authors propose and identify the Atlantic-West Pacific trans-basin SST mode as a significant mode of global inter-oceanic interdecadal variability based on observational and model evidence. They discover that this mode started to change from a negative to a positive phase in the 1990s, which led to significant changes in the regional SST system in the Indian Ocean and the Arabian Sea. As a result, the warming rate of the Arabian Sea began to significantly accelerate in the 1990s. The Atlantic-West Pacific ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
