Regional climate modeling in the Lower Mississippi River Valley for water resources assessments
We have implemented a regional climate model (RCM) covering the Lower Mississippi River Valley (LMRV) and the northern coastal zone of the Gulf of Mexico. The RCM configuration is based on the Weather Research and Forecast (WRF) model, used to downscale the IPCC AR4 global climate projections from the NASA GISS ModelE. The RCM downscaling efforts have been targetted to support impacts assessment and decision-making in water resources management, since water availability and quality are fundamental for the economic activity in the LMRV region. We are also incorporating the new regional climate projections into a data server, which will serve the needs of economic and risk management frameworks in order to facilitate climate impacts assessments under future regional climate change scenarios at relevant spatial scales. We will present initial results from a set of decade long simulations and the lessons learned.
