PO31D:
Variability of Ocean Circulation in the Tropical Indo-Pacific Warm Pool and Its Climatic and Environmental Impact I


Session ID#: 7912

Session Description:
The warm pool in the tropical Indian and Pacific Oceans and its associated ocean-atmosphere interactions play a vital role in the variability of regional and global climate. Strong western boundary currents (WBCs) and Indonesian Throughflow modulate the heat, mass and freshwater budgets of the warm pool, which is of great importance to the global climate predictability.  Among them, ENSO and Indian Ocean Dipole are the strongest interannual climate modes that interact over and through the Indonesian seas.  The tropical and extra-tropical exchange through the WBCs is believed to influence the decadal and longer time-scale variability of the tropical oceans.  A number of field experiments and modeling efforts have been designed and implemented to understand the dynamics of the processes that give rise to the variability and predictability of the Indo-Pacific ocean circulation and climate.  This session seeks contributions with topics including oceanic circulation variability in the western tropical Pacific and eastern Indian Oceans, interactions with the extra-tropics, the Indonesian Throughflow, and air-sea interactions associated with the warm pool. Contributions are also encouraged about the impact of the Indo-Pacific oceans on the variability and predictability of Asian monsoon, typhoons, and multi-disciplinary studies at times scales from diurnal, intra-seasonal, interannual, to decadal.
