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

It is important to investigate the propagation from meteorological to hydrological drought and
its potential influence factors, which helps to reveal drought propagation process, thereby …

A monthly global dataset of a multiscalar drought index is presented and compared in terms
of spatial and temporal variability with the existing continental and global drought datasets …

The knowledge of soil moisture spatial variability is an important issue for hydrological and
climatic studies. This paper investigates the soil moisture spatial pattern obtained from spot …

At present, the Standardized Precipitation Index (SPI) is the most widely used drought index
to provide good estimations about the intensity, magnitude and spatial extent of droughts …

Under the background of global warming, the acceleration of water cycle process will
aggravate the risk of hydrological drought in the river basin. The Yellow River basin (YRB) is …

The influence of climate variation on the availability of water resources was analyzed in the
headwaters of the Tagus River basin using two drought indices, the standardized …

The analysis of the physical processes involved in a conceptual model of soil water content
balance is addressed with the objective of its application as a component of rainfall–runoff …

The study of precipitation trends is critically important for a country like India whose food
security and economy are dependent on the timely availability of water such as 83% water …

In this study we assessed the impact of meteorological droughts on streamflow droughts in
187 river basins of the Iberian Peninsula. For each basin we correlated the 1 mo to 48 mo …
