Two-way interaction among the Pacific, Atlantic, and Indian Ocean basins is increasingly recognized as a key factor in understanding climate variability on seasonal to multi-decadal timescales. This session, to be convened by the CLIVAR Tropical Basin Interaction Research Focus at the 2021 AGU Fall Meeting, highlights studies that examine atmospheric and oceanic pathways linking the tropical basins, as well as the mechanisms underpinning these linkages. We welcome studies using observational data, paleoclimate proxies, and models of any complexity (from theoretical to global climate models). Potential topics include, but are not limited to, the influence of the tropical Atlantic and Indian Oceans on ENSO and Pacific decadal variability; variability of the Indonesian Throughflow; multi-decadal modulation of basin interaction; and basin interaction in climate change. Studies examining the potential benefit of basin interaction for seasonal prediction are also welcome, as are studies examining how climate model biases affect the simulation of basin interaction.
