PL31A:
Tropical Indo-Pacific Ocean Circulation and Climate Variations I

Session ID#: 92658

Session Description:
Tropical Indo-Pacific ocean circulation and climate variations. The Indo-Pacific warm pool plays a vital role in the coupled ocean-atmosphere evolution of the tropical and extratropical oceans, affecting interannual-decadal climate variability and change, including ENSO, the Indian Ocean Dipole, and mid- to high-latitude climate variations. The Indian and Pacific basins exchange mass and energy through the Indonesian Throughflow and also via atmospheric teleconnections. The warm pool is influenced strongly by the ocean circulation in the western Pacific and eastern Indian Oceans. The area has been the focus of recent ocean observations and climate studies aiming to better understand the dynamics and predictability of the variability in the Indo-Pacific ocean circulation and climate. This session seeks contributions on topics including oceanic circulation variability in the western Pacific Ocean, Indonesian seas, South China Sea, and eastern Indian Ocean, the Indonesian and South China Sea Throughflows, tropical air-sea coupling, tropical-extratropical interactions, and impacts on monsoon/typhoon predictability studies at times scales ranging from diurnal, intra-seasonal, interannual, decadal, and centennial impacts of global warming.
