HCM에서 ENSO 변동성에 대한 인도양의 영향

Abstract

The current study aims to identify how Indian Ocean variability affects ENSO variability in the presence of local thermodynamic coupling only. This is addressed mainly through numerical experiments with a hybrid coupled model (HCM). We adopt two different strategies for simulating the SSTAs of the Indian Ocean in the HCM. In the first strategy, the SSTA in the Indian Ocean is statistically predicted based on the state of the tropical Pacific (i.e., no local thermodynamic air-sea coupling). In the second strategy, the AGCM is coupled to a thermodynamic slab mixed layer model in the Indian Ocean (i.e., active thermodynamic air-sea coupling).
