Role of the ENSO–Indian Ocean coupling on ENSO variability in a coupled GCM
نویسندگان
چکیده
[1] The effect of the Indian Ocean on El Niño/La Niña life cycles has been studied using 200-yrs simulation data of a coupled GCM. The results show that the interactive feedback between the ENSO and the Indian Ocean holds the key to the rapid transition to an opposite phase. This remote impact of the IndianOceanSSTanomaly is linked to the change of zonal wind stress in the western Pacific, which leads to a rapid demise of El Nino/La Nina. Without the involvement of the IndianOcean, the phase transition ismuch slower. This role of the ENSO–Indian Ocean coupling on ENSO transition is consistent with that derived from the observational analysis. Citation: Kug, J.-S., T. Li, S.-I. An, I.-S. Kang, J.-J. Luo, S.

Contrasting Indian Ocean SST variability with and without ENSO influence: A coupled atmosphere-ocean GCM study
In this study, we perform experiments with a coupled atmosphere-ocean general circulation model (CGCM) to examine ENSO’s influence on the interannual sea-surface temperature (SST) variability of the tropical Indian Ocean. The control experiment includes both the Indian and Pacific Oceans in the ocean model component of the CGCM (the Indo-Pacific Run). The anomaly experiment excludes ENSO’s infl...

12 The impact of Indo-Pacific climate feedback on the dynamics of El Niño Southern Oscil13 lation (ENSO) is investigated using an ensemble set of Indian Ocean decoupling experiments 14 (DCPL), utilising a millennial integration of a coupled climate model. It is found that elim15 inating air-sea interactions over the Indian Ocean results in stronger ENSO variability with 16 various degrees of am...
متن کاملA Simple Model for the Pacific Cold Tongue and ENSO*
A conceptual model is constructed based upon the Bjerknes hypothesis of tropical atmosphere–ocean interaction. It is shown that strong feedbacks among the trade winds, equatorial zonal sea surface temperature contrast, and upper-ocean heat content occur in the tropical Pacific basin. Coupled atmosphere–ocean dynamics produce both the strong Pacific cold-tongue climate state and the El Niño–Sout...
متن کاملImpacts of the Indian Ocean on the ENSO cycle
[1] This study examines the impacts of the Indian Ocean on the ENSO (El Niño-Southern Oscillation) cycle by performing experiments with a coupled atmosphere-ocean general circulation model (CGCM). In one of the experiments, the ocean model domain includes only the tropical Pacific Ocean (the Pacific Run). In the other experiment, the ocean model domain includes both the Indian and tropical Paci...
متن کاملTropical climate variability: interactions across the Pacific, Indian, and Atlantic Oceans
Modes of tropical climate variability, such as the El Niño– Southern Oscillation (ENSO), the Indian Ocean Basinwide Mode (IOBM), the Indian Ocean Dipole (IOD), and the Atlantic Equatorial Mode (AEM) (sometimes referred to as the Atlantic Zonal Mode, or Atlantic Niño) interact most readily via the atmosphere. Sea surface temperature anomalies (SSTAs) in the tropics drive changes in the Walker Ci...
