This report describes the morphology of the 2012 summer U.S. central Great Plains drought, placing the event into a historical context, and providing a diagnosis of its proximate and underlying causes. Precipitation deficits for the period May-August 2012 averaged over the central Great Plains were the most severe in the instrumental record since 1895, eclipsing the height of the Dust Bowl. The drought developed suddenly, with little forewarning of failed rains. Climate simulations and empirical analysis suggest that neither the effects of ocean surface temperatures nor changes in greenhouse gas concentrations produced a substantial summertime dry signal over the central Great Plains during 2012. This assessment report clarifies whether such drought could have been anticipated, and it suggests investments that may lead to better guidance on mitigating effects of future drought. Figures. This is a print on demand report.
