Although there are many climate patterns and systems that exist at widely varying time scales, the El Nino/Southern Oscillation (ENSO) phenomenon remains recognised as the core driver of climate variability in eastern Australia. The term 'ENSO' is also intended to include the now infamous La Nina pattern. Climate forecasts available for the northern cropping region, such as those based on or similar to the 'SOI-phase system', have been demonstrated to provide significant and relatively high skill when verification tests have been applied to assess all those forecasts in real-time over the past 10 years. Other climate forecast systems, especially those that also utilise Indian Ocean inputs, tend to provide less skill for a region such as the northern cropping region but otherwise provide high skill in regions such as Western Australia. New developments in general circulation model (GCM) forecasts (whether they are produced in Australia or in other countries) suggest enhanced and useful forecast skill for seasonal and longer time periods for the northern cropping region in the future. With further development and testing, GCM forecast systems may provide increased lead time and greater forecast accuracy than currently applied statistically-produced systems.
