The Asian monsoon (AM) and the El Nino-Southern Oscillation (ENSO) are dominant atmospheric-ocean phenomena on the Earth and affect the climates of Asia, Oceania and circum-Pacific regions. During the Cenozoic, the climate of these areas changed drastically, but the behaviors of the Asian monsoon and the tropical ocean-atmosphere interactions like the ENSO were not fully understood. From July 2013 to December 2016, IODP conducted a series of expeditions such as 346 (Asian Monsoon), 353 (Indian Monsoon Rainfall), 354 (Bengal Fan), 355 (Arabian Sea Monsoon), 356 (Indonesian Throughflow), 359 (Maldives Monsoon and Sea Level), 361 (Southern African Climate), and 363 (Western Pacific Warm Pool) that are related to the AM and tropical Pacific climate evolution and its interaction with global climate system in NW and tropical Pacific and Indian Ocean regions, and exciting results are coming out. We believe it is timely to start synthesizing the results of these cruises and update and exchange information and ideas to promote our understanding of the AM and tropical Pacific evolution, variability, their controlling factors, and their interaction with global climate system during the Cenozoic. On orbital and millennial timescales, studies on the response of the AM and the ENSO to climate forcing are intensively studied using various archives such as sediments, speleothems, corals, etc., during the last decade. Presentations and discussions on the above topics from various backgrounds (proxy and modeling studies) are highly welcome.
