Rethinking Australian drought risk, its long-term variability and processes

干旱风险描述的是暴露在干旱下造成损害的可能性。该项目旨在从根本上重塑我们如何定义、描述和理解澳大利亚的干旱风险。将采用一个干旱风险框架，其中包括调节干旱影响的全部特征，即复发频率、持续时间、严重程度、季节性和空间范围。将审查干旱风险的长期变化，并确定基于过程的气候风险因素。提高对干旱风险长期变化的性质和原因的认识，对于改善农业和水资源部门的干旱风险管理至关重要。

Drought risk describes the likelihood that damage will result from exposure to drought. This project aims to fundamentally reshape how we define, characterise and understand drought risk in Australia. A framework for drought risk will be applied that includes the complete range of characteristics that modulate the impacts of drought, which are the frequency of recurrence, duration, severity, seasonality and spatial extent. Long-term changes in drought risk will be examined and the process-based climatic risk factors will be identified. Advancing knowledge on the nature and causes of the long-term changes in drought risk is crucial to improving risk management of drought in the agricultural and water resource sectors.
