Scope	El Nino/Southern Oscillation, Indian Ocean Dipole, Atlantic Nino, and Atlantic Meridional Mode are ocean-atmosphere interaction phenomena in the tropics. These phenomena have an interannual timescale of two- to seven-year period. It has been pointed out that they are related to various phenomena of shorter (e.g., intraseasonal) and longer (e.g., quasidecadal to multidecadal) timescales as well as phenomena of various spatial scales. In addition to interactions among the tropical phenomena and climate change, links with atmospheric and oceanic variations in mid to high latitudes have been discussed in past studies. These phenomena strongly affect weather, climate, and climate variations over the globe including those in Japan. To enhance our understanding of variability of tropical ocean-atmosphere interaction phenomena and other related phenomena, cooperation between various fields (meteorology, oceanography, climatology, etc.) needs to be strengthened. In this session, presentations and discussions about interannual tropical ocean-atmosphere interaction phenomena, Madden-Julian Oscillation (MJO), tropical cyclones (typhoon), quasi-decadal to multi-decadal variations and other related phenomena by various researchers of atmosphere and ocean, weather and climate, and tropics and extra-tropics, will be carried out to promote research on spatial and temporal multi-scale ocean-atmosphere interaction phenomena in the tropics. We welcome submissions on theoretical, observational, and modeling studies.
