Tropical ocean-atmosphere interactions exert a significant impact on regional and global climate on a broad range of spatio-temporal scales. Since the 1980s, in-situ and satellite observations, reanalysis products, and advancements in climate modeling have led to depicting various aspects of intraseasonal (e.g., MJO), interannual (e.g., ENSO, IOD, and Atlantic Nino) and decadal (e.g., IPO) variability in the tropical ocean basins and their linkages with tropical (e.g., monsoons) and extratropical (e.g., storm track) climate. Newer studies find an active role of salinity in tropical ocean-atmosphere interaction, including tropical cyclone intensification. Other recent studies highlight the tropical inter-basin coupling among the Pacific, Indian Ocean, and Atlantic in seasonal prediction of the Asian summer monsoon and decadal redistribution of ocean heat content associated with the so-called "hiatus" of global warming. Long term change in the Pacific Walker circulation has been recapturing attention in terms of the pattern effect of warming on climate feedback and sensitivity against radiative forcing as well as ENSO modulations under a warmer climate. A variety of processes are mutually interrelated and shape the climate, its variability, and change. To examine these challenging issues from various perspectives and foster understanding of the role of tropical ocean-atmosphere interaction in the climate system, this session offers a forum to discuss recent progress in observational, modeling and theoretical studies of multi-scale ocean-atmosphere interaction in the tropics.
