Owing to the rise in water demand and looming climate change, recent years have
witnessed much focus on global drought scenarios. As a natural hazard, drought is best …

Drought is a stochastic natural hazard that is instigated by intense and persistent shortage of
precipitation. Following an initial meteorological phenomenon, subsequent impacts are …

Under global climate change and pressure from human activities, water scarcity is becoming
a major concern in the quest for regional sustainable development in the Yellow River Basin …

This study elucidates drought characteristics in China during 1980–2015 using two
commonly used meteorological drought indices: standardized precipitation index (SPI) and …

The authors propose a new climatic drought index: the standardized precipitation
evapotranspiration index (SPEI). The SPEI is based on precipitation and temperature data …

Beguería, S., SM Vicente-Serrano, F. Reig, and B. Latorre, 2014: Standardized precipitation
evapotranspiration index (SPEI) revisited: Parameter fitting, evapotranspiration models …

The monitoring and analysis of drought have long suffered from the lack of an adequate
definition of the phenomenon. As a result, drought indices have slowly evolved during the …

In this study we analyzed the sensitivity of four drought indices to precipitation (P) and
reference evapotranspiration (ETo) inputs. The four drought indices are the Palmer Drought …

The relationship between the satellite-based Vegetation Condition Index (VCI) and a
number of frequently used meteorological drought indices was evaluated using data from all …
