| Scope | The Asian Monsoon (AM) is an inter-hemispheric atmospheric system driven by the thermal contrast between ocean and land and has a significant impact on the global climate. The uplift of Himalaya and Tibetan Plateau (HTP) has been considered to have played a significant role in the establishment and intensification of the Asian monsoon, but its importance is still controversial. On the other hand, a comparison of AM evolution process with global climatic changes suggests that AM evolution during Cenozoic is significantly affected by global climate changes most likely through pCO2. In addition, Indo-Pacific oceanic climate condition is also essential for the land-ocean thermal contrast as well as water vapor circulation because these areas have the largest heat content in the world ocean and supply heat and moisture to the atmosphere.
In this session, we promote understanding of AM and Indo-Pacific climate evolution, variability at multiple time scales (millennial to tectonic time scale) as well as their controlling factors, and their interaction with the global climate system. Presentations from various archives such as piston cores, DSDP/ODP/IODP cores as well as land sections relying on a wide panel of paleoenvironmental proxy are welcome (e.g. Geochemistry, Geophysics, Sedimentology, Micropaleontology as well as modeling studies). We also welcome presentations from older time periods such as Mesozoic and Paleozoic for a better understanding of the evolution of the monsoon system during the Phanerozoic.
