| Abstract | The El Niño-Southern Oscillation (ENSO) profoundly affects Australian weather, climate, ecosystems and socio-economic sectors. As such, efforts have been made to better understand and predict its impacts, particularly in light of observed and projected changes in ENSO and its climatic impacts. In this Review, we summarise the advances in understanding the ENSO-Australian climate relationship, including the mechanisms and corresponding climatic impacts. Notably, ENSO's influence is most coherent during austral spring, with La Niña exhibiting a more robust influence on rainfall than El Niño, and Central Pacific El Niño events having greater impacts than Eastern Pacific events. These effects can be amplified during prolonged ENSO episodes and land-atmosphere feedbacks, influenced by local sea surface temperature and moisture advection, altered by interactions with other climate modes, and modulated on multidecadal timescales. While ENSO predictability has improved with advanced understanding of ocean processes and dynamical forecasting, predicting its impacts is challenged by large internal atmospheric variability. Ongoing changes in ENSO underscore the need for strategic research, continuous in-situ monitoring, efforts to reduce climate model biases and develop a deeper understanding of the processes contributing to the anthropogenically induced changes in Pacific background surface temperatures, which collectively help inform adaptation strategies. |
