スコープ和文The Asian Monsoon (AM) is a part of interhemispheric atmospheric phenomena that is driven by the thermal gradient between ocean and land. Contrasts of insolation, heat content and latent heat transfer between ocean and land may have affected the behavior of the AM in the past, but the proxy records are occasionally controversial and do not show a clear picture of the AM variability. Recent proxy and modeling studies suggest that glacial pCO2 cycles could be related to the position of southern westerlies, which is sensitive to interhemispheric heat imbalance. Because monsoon is driven by the heat imbalance, knowledge on the variability of the AM is important to understand the behavior of the global climate system. In this session, presentations on the reconstruction of long-term AM variability from various archives such as IODP expedition cores, discussion on its forcing, and the roles of the AM in global climate changes are welcome.
