| 英文摘要 | The Indonesian Throughflow (ITF) regulates heat and freshwater distributions over the Indo-Pacific Oceans and fundamentally affects the climate. The past decade has witnessed acute interannual variations in the volume transport within the Makassar Strait-the main ITF inflow passage-such as a decrease of similar to 4 Sv (1 Sv equivalent to 106 m3 s-1) in 2015-2016 boreal winter and an enhancement of similar to 3 Sv in 2017 autumn, relative to a mean transport of similar to 12 Sv. The Pacific Ocean dynamics, dictated largely by El Ni & ntilde;o-Southern Oscillation (ENSO), cannot fully explain these variations, and a quantitative understanding of the Indian Ocean (IO) dynamics involved in the ITF transport variability remains lacking. Here, by performing regional forcing experiments with a 0.1 degrees ocean general circulation model, we reveal that the wind-driven IO dynamics have operated as a buffering effect for similar to 56% of the time and a reinforcing effect for similar to 44% of the time during the past decade. Notably, the IO dynamics buffered the weakened ITF by similar to 2 Sv in 2015-2016 winter and contributed to the enhanced ITF by similar to 0.5 Sv in 2017 autumn. The buffering effect of IO winds is commonly seen during strong ENSO events, while the reinforcing effect arises from Indian Ocean Dipole (IOD) events independent of ENSO. Our study aids in the prediction of the ITF strength under the amplifying ENSO and IOD variabilities expected in a warming climate. |
