Extreme climate events,
Research by Omid Mazdiyasni and Amir AghaKouchak (University of California, Irvine), funded by CPO’s Modeling, Analysis, Predictions, and Projections program, was recently published in Proceedings of the National Academy of Sciences (PNAS). This study applied the Cramer-von Mises change point detection test statistic approach, a technique common to economics and finance, to analyze changes in concurrent meteorological droughts and heatwaves from 1960-2010. While the authors found no significant changes over time in meteorological drought, the concurrence of droughts and heatwaves have significantly increased specifically in the south, southeast, and western U.S.
