【 摘 要 】

Drought is one of the most complex and costly natural hazards. It develops slowly and can affect a large area meaning it can be difficult to pinpoint the start and/or the end of an event. Drought is primarily driven by a deficit in precipitation but an additional level of complexity is introduced when these deficits in precipitation propagate to other parts of the hydrological cycle such as soil moisture, river flows and groundwater levels over different time scales.
