The importance of tropical Indo-Pacific modes on global climate is evident in the ongoing strong El Nino event and the Indian Ocean leading surface ocean warming. But with a short observational record that misses many different climate states, to understand how the complex tropical circulation and the resulting hydroclimate variability that is essential to billions of people will change in the future, longer records from different mean climates are required. Recent advances in Paleoceanographic and Paleoclimate studies have greatly contributed to our understanding of the link between the Indian Ocean and the Pacific Ocean and raised new questions related to hydroclimate in the region. This session invites presentations of research designed to investigate the paleoclimate changes across different time scales from the common era, Quaternary and deeper times, using a variety of physical, geochemical and biological proxies. Contributions that discuss or even model the specific local processes and regional factors in the Indo-Pacific along with their links to the global climate system are particularly welcome. Studies on the interaction between the low and high latitudes and the roles of low latitude processes, the manifestation and mechanisms of rapid climatic events and transitions, the relationship between the monsoon and ITCZ movement, and their controlling factors are encouraged.
