SPI - Standardized Precipitation Index from CRU for EU and USA

open access: yes, 2022
The "Standardized Precipitation Index" (SPI) is used to describe extremely dry or wet climate situations. The advantages of SPI usage are: Only precipitation data are needed for the calculation of the index.

Predicting Standardized Streamflow index for hydrological drought using machine learning models

open access: yesEngineering Applications of Computational Fluid Mechanics, 2020
Hydrological droughts are characterized based on their duration, severity, and magnitude. Among the most critical factors, precipitation, evapotranspiration, and runoff  are essential in modeling the droughts. In this study, three indices of drought, i.e.

Application and Comparison of Standardized Precipitation and Standardized Precipitation Evapotranspiration Indices for Evaluating Meteorological Drought Condition of Tehran Province [PDF]

open access: yesمدیریت بیابان, 2014
Numerous indicators for drought monitoring in different time scales have been used for monthly and yearly data series. One of the limitations of conventional indicators such as the Standardized Precipitation Index (SPI) is no attention to the water ...

A Standardized Precipitation Index (SPI) Climatology for the Continental U.S.

open access: yes, 2023
The standardized precipitation index SPI (McKee et al. 1993) was designed to standardize precipitation timeseries across an observational record in order to compute precipitation anomalies in both time and space.

Unraveling the pertinence of drought indices in the changing climate

open access: yesEnvironmental Research Letters, 2023
The increasing divergence/disagreement between the meteorological drought indicators, majorly due to the changing climate conditions, has disputed their pertinency in the monitoring and modeling of drought events.
