Average Forecast Errors Using MM5 and WRF Over Complex Terrain: Utah, July/August 2003 and January/February 2004

Abstract

This report documents average weather forecast errors associated with two mesoscale models run over northern Utah during two months in the summer (2003) and two months in the winter (2004). The models used were the Pennsylvania State University/National Center for Atmospheric Research Mesoscale Model Version 5 (MM5) and the Weather Research and Forecast (WRF) model, version 1.3. The forecast values of surface temperature, dew-point temperature, wind speed, and wind direction were compared to station observation data obtained through the University of Utah MesoWest Cooperative.
