A copula-based joint deficit index for droughts

31 Mar 2010 | Contributor(s): Rao S Govindaraju

Current drought information is based on indices that do not capture the joint behaviors of hydrologic variables. To address this limitation, the potential of copulas in characterizing droughts from multiplevariables is explored in this study. Starting from the standardized index (SI) algorithm, a...

A seasonal-scale climatological analysis correlating spring tornadic activity with antecedent fall–winter drought in the southeastern United States

14 Jun 2011 | Publications | Contributor(s): Dev Niyogi

Using rain gauge and satellite-based rainfall climatologies and the NOAA Storm PredictionCenter tornado database (1952–2007), this study found a statistically significant tendency forfall–winter drought conditions to be correlated with below-normal tornado days the followingspring in north...

A spatio-temporal drought analysis for the Midwestern US

15 Jun 2009 | Publications | Contributor(s): Rao S Govindaraju, Dev Niyogi

Droughts are prolonged abnormalities of moisture deficits that vary widely across temporal and spatial scales. Many hydrometeorologic variables are used to monitor the status of a drought. However, because of the dependence structure between all affecting variables under various temporal windows,...

Achieving Sustainable Irrigation Water Withdrawals: Global Impacts on Food Production and Land Use

27 Sep 2017 | Publications | Contributor(s): Jing Liu, Tom Hertel, Richard Lammers, Alexander A Prusevich, Uris Lantz C Baldos, Danielle Grogan, Steve Frolking

Unsustainable water use challenges the capacity of water resources to ensure food security and continued growth of the economy. Adaptation policies targeting future water security can easily overlook its interaction with other sustainability metrics and unanticipated local responses to the...

Analyzing Water Scarcity in Global CGE Models

08 Sep 2017 | Publications | Contributor(s): Jing Liu, Tom Hertel, Farzad Taheripour

Incorporating water into a computable general equilibrium (CGE) model operating at global scale can be extremely demanding due to the absence of standardized data, the sheer dimensions caused by intersecting river basins with countries, and difficulties to model demand for and supply of water....
