- Abstract
Drought is a multifaceted phenomenon driven by both natural climate fluctuations and human activities. Unlike traditional, slow-developing droughts, flash droughts (FDs) emerge suddenly and intensify rapidly, posing significant challenges for natural resource management. The lack of effective tools to quantify FDs exacerbates stakeholders' concerns, particularly due to the risks they pose to water management, food security, and environmental sustainability. Given their multifaceted nature, FDs evolve across both time and space, and traditional two-dimensional methods often fail to capture these dynamics. To address this issue, we developed a three-dimensional spatiotemporal framework for identifying flash droughts to analyse the spatial... (More)
Drought is a multifaceted phenomenon driven by both natural climate fluctuations and human activities. Unlike traditional, slow-developing droughts, flash droughts (FDs) emerge suddenly and intensify rapidly, posing significant challenges for natural resource management. The lack of effective tools to quantify FDs exacerbates stakeholders' concerns, particularly due to the risks they pose to water management, food security, and environmental sustainability. Given their multifaceted nature, FDs evolve across both time and space, and traditional two-dimensional methods often fail to capture these dynamics. To address this issue, we developed a three-dimensional spatiotemporal framework for identifying flash droughts to analyse the spatial and temporal features and migration patterns of FDs. The results reveal that in China, flash droughts tend to migrate north and southeast, with this trend becoming increasingly pronounced as flash drought intensity increases. From 1982 to 2022, South China and Northwest China experienced significant increases in flash drought events. Flash droughts primarily occur during the growing season, with a rising proportion of events leading to heightened risks for crop yields and vegetation growth. Additionally, the percentage of flash droughts that begin within one pentad has significantly increased, indicating shorter onset times and an accelerated occurrence rate.
