This project aims to determine the magnitude, frequency and duration of dry and wet extremes across the Australian continent over the last thousand years and examine landscape responses to such climate extremes. Using terrestrial records from key lake locations, the project expects to construct a record of mega-lakes and mega-droughts and determine whether such climatic phenomena are becoming more frequent or severe through time. The project will develop palaeoclimatic data at sub-centennial resolution, examining the spatial coherence of the climate extremes. The project will integrate this with both the historical record and global climate modelling, allowing us to assess the dominant oceanographic and atmospheric conditions that lead to such extremes.

该项目旨在确定过去一千年来整个澳大利亚大陆干燥和潮湿极端的大小，频率和持续时间，并检查对这种气候极端的景观反应。该项目使用关键湖泊地点的陆地记录，希望构建巨型湖泊和大型干旱的记录，并确定这种气候现象是否变得越来越频繁或随着时间的流逝变得越来越严重。该项目将以次年分辨率开发古气候数据，研究气候极端的空间连贯性。该项目将将其与历史记录和全球气候建模融为一体，使我们能够评估导致这种极端的主要海洋学和大气条件。
