Australia's variable rainfall - how dry or wet can it really get?

澳大利亚的降雨量变化无常，这意味着现有的天气记录太短，无法计算出干旱和洪水带来的真正风险。该项目旨在量化来自印度-太平洋中纬度地区的降雨的自然变化程度，从而在长期背景下评估最近的极端降雨和未来的预测。该项目希望通过对南印度洋具有湿度的1000年风暴的重建，对澳大利亚和南极洲之间的大气湿度预算做出新的估计。这些新信息对于水资源管理者来说是至关重要的，这样他们就可以正确地计算（并最终做好准备）澳大利亚与降雨相关的最坏风险。

Australia’s rainfall is extremely variable, which means existing weather records are too short to calculate the true risk posed by droughts and floods. This project aims to quantify how naturally variable the rainfall coming from the Indo-Pacific mid-latitudes is, allowing recent rainfall extremes and future projections to be assessed in a long-term context. This project expects to produce new estimates of atmospheric moisture budgets between Australia and Antarctica based on a novel, 1000-year length reconstruction of moisture-bearing southern Indian Ocean storms. This new information is critically needed by water managers so that they can properly calculate (and ultimately prepare for) the worst of Australia’s rainfall-related risks.
