El Niño and La Niña events have a profound influence on Australian drought conditions and rainfall. Forecasting is hampered by short climate records, which do not capture the full range of El Niño dynamics. This project aims to generate records of unprecedented length and spatial coverage from key sites across the western and central equatorial Pacific. Five hundred years of continuous, monthly-resolution climate data will be integrated with output from state-of-the-art climate model simulations to distil the key processes that cause El Niño to vary. This project aims to provide major advances in determining the full range of El Niño and La Niña behaviour, leading to improved forecasts of future changes, with consequences for Australia's water security.

厄尔尼诺和拉尼娜事件对澳大利亚的干旱状况和降雨量有着深远的影响。气候记录较短，无法捕捉到厄尔尼诺现象的全部动态，从而阻碍了预测。该项目旨在从赤道中西部太平洋的关键地点生成前所未有的长度和空间覆盖范围的记录。五百年的连续、每月分辨率的气候数据将与最先进的气候模型模拟的输出相结合，以提炼出导致厄尔尼诺现象变化的关键过程。该项目旨在在确定厄尔尼诺和拉尼娜现象的全部范围方面取得重大进展，从而改进对未来变化的预测，从而对澳大利亚的水安全产生影响。
