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. The impacts of tropical Atlantic and Indian Ocean on the tropical Pacific SST variability also start to garner much attention. Interacting 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. Submission from foreign speakers will be welcomed.
