Deriving local climate information from global models

Raymond W. Arritt, Department of Agronomy, Iowa State University

Raymond Arritt’s research emphasis is on regional-scale atmospheric processes, focusing on the interactions of the atmosphere with terrain and land-surface properties. Adaptation to climate change requires decision making at the scale of cities to states to nations.  In contrast global climate models solve their equations at points separated by 100 kilometers or more. This limitation means that they often do not realistically include influences on local and regional climate such as terrain and coastlines, or small-scale weather and climate phenomena such as thunderstorms. This talk surveys the nature of this scale mismatch, and describes methods that are used for obtaining information at decision-relevant scales from spatially coarse global climate models.
