A copula-based joint deficit index for droughts

31 Mar 2010 | Publications | 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,...

Market-mediated environmental impacts of biofuels

31 Jul 2014 | Publications | Contributor(s): Tom Hertel, Wallace E. Tyner

This paper surveys the evidence on market-mediated environmental impacts of biofuels, with special attention to the indirect greenhouse gas emissions stemming from land cover change in the wake of increased demand for biofuel feedstocks. We find clear evidence that market mediated land use...
