The project aims to develop a new method for understanding drought drivers in eastern Australia and how well these are portrayed by climate models. The intended outcome of the project is to provide a framework for evaluating climate models on their representation of drought drivers and then use this information to develop improved downscaling schemes. Traditional downscaling approaches do not capture changes in variability in rainfall and evaporation at interannual and interdecadal timescales. This project aims to address this problem by providing a comprehensive drought downscaling framework which will provide inputs to water sharing plans that can be used to assess the future risks of droughts in catchments across New South Wales.

该项目旨在开发一种新的方法来了解澳大利亚东部的干旱驱动因素，以及气候模型对这些因素的描述。该项目的预期成果是提供一个框架，用于评估气候模型对干旱驱动因素的代表性，然后利用这一信息制定改进的降尺度方案。传统的降尺度方法不能捕捉年际和年代际时间尺度上降雨和蒸发变化的变化。该项目旨在解决这一问题，提供一个全面的干旱降尺度框架，为可用于评估新南威尔士州集水区未来干旱风险的水资源共享计划提供投入。
