Multi-scale ocean-atmosphere interaction in the tropics has a significant influence on the global climate via atmospheric teleconnection. Since the 1980s, many studies have investigated the tropical interannual variability such as the El Nino/Southern Oscillation and Indian Ocean Dipole, its link to the tropical intraseasonal variability, and the tropical-extratropical interaction. Recent studies highlight a possible link between the interdecadal Pacific Oscillation and the global warming hiatus in the 2000s, and a role of salinity in the tropical ocean-atmosphere interaction with new satellite salinity observations. Due to interactions between different time scales, between different ocean basins, and with the extratropics, the tropical ocean and atmosphere play a key role in climate formation, variability and change. To better understand and examine those issues from various perspectives, this session offers a forum to discuss recent progress in observational, modeling and theoretical studies of multi-scale tropical ocean-atmosphere interaction.
