Development of a flash drought intensity index [PDF]
Atmosphere, 2021 <p>Flash droughts are characterized by a period of unusually rapid drought intensification over sub-seasonal time scales that often take vulnerable stakeholders by surprise given their rapid onset. Various studies have shown that flash drought is more likely to develop when extreme weather conditions persist over the same region for ...

Drought Monitoring With Spectral Indices Calculated From Modis Satellite Images In Hungary
Journal of Environmental Geography, 2015 In this study a new remote sensing drought index called Difference Drought Index (DDI) was introduced. DDI was calculated from the Terra satellite’s MODIS sensor surface reflectance data using visible red, near-infrared and short-wave-infrared spectral ...

GTDI: a game-theory-based integrated drought index implying hazard-causing and hazard-bearing impact change [PDF]
Natural Hazards and Earth System SciencesDeveloping an effective and reliable integrated drought index is crucial for tracking and identifying droughts. The study employs game theory to create a spatially variable weight drought index (game-theory-based drought index, GTDI) by combining two ...

Actual Precipitation Index (API) for Drought Classification [PDF]
Earth Systems and Environment, 2021 AbstractThe Standard Precipitation Index (SPI) is a widely used statistical technique for the characterization of droughts. It is based on a probabilistic standardization procedure, which converts a Gamma-type probability distribution function (PDF) into a normal (Gaussian) standard series with zero mean and unit standard deviation.
