A three-dimensional C-Vine copula-based composite flash drought index for global flash drought identification

Despite increasing research on Copula-based conventional seasonal drought indices, studies on multivariate flash drought identification remain limited. This study employed three variables—the difference between precipitation and potential evapotranspiration (P–PET), soil moisture (SM), and runoff (R...
