An important step in developing climate forecasts is the identification of an appropriate set of predictors. Seasonal rainfall forecasts for South Australia ( SA ) currently have low predictive skill. It is hypothesised that this is because the large‐scale climate processes influencing SA 's rainfall variability have yet to be completely identified and therefore are not adequately represented in forecast models. Here, relation...

Seasonal rainfall forecasts are an important tool for risk management across many sectors. However, significant challenges arise in the development of skilful and practically useful seasonal forecasts for regions where the temporal and spatial variability of rainfall is large and/or knowledge about what causes this variability is in its infancy. This is evident in the state of South Australia ( SA ), where seasonal rainfall cu...
