Assessing vulnerability through storm transposition
Historical climate data for the Midwestern U.S. show substantial regional variability in the occurrence of extreme rainfall events. Climate projections for the region based on both statistically downscaled General Circulation Models and Regional Climate Models show significant inter-model variability in the magnitude and frequency of extreme rainfall events. As a result, these climate projections cannot be used alone to adaptively manage water resources in a changing climate. We believe that storm transposition provides an effective way to evaluate the vulnerability from extreme rainfall and flooding.
