Causal Links on Interannual Timescale Between ENSO and the IOD in CMIP5 Future Simulations

What is it about?

The global climate is influenced by several major climate modes, including the El Niño–Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD). In the present study, we investigate the future connection between ENSO and the IOD as understanding their relationship is important for future climate extreme predictions in and around Indian Ocean and Pacific Ocean. We used data from 22 different climate model simulations for the 2006–2100 period. The results indicate significant impact of the IOD on ENSO in 10/22 models, while the influence of ENSO on the IOD is found in 14/22 models. This study allows us to gain insight into the future relationship between ENSO and the IOD, as well as understanding the consistency of climate models in simulating the links between these two climate modes.
