ABSTRACT
The skill of a mesoscale-model-based model output statistics (MOS) system that provided hourly forecasts for 18 sites over northern Utah during the 2002 Winter Olympic and Paralympic Games is evaluated. The MOS system was developed using three winters (November-April 1998/99, 1999/2000, and 2000/01) of forecasts by the fifth-generation Pennsylvania State University-National Center for Atmospheric Research Mesoscale Model (MM5) and observations from Olympic venues and transportation corridors.
MOS temperature, relative humidity, wind speed, and wind direction forecasts were considerably more accurate than those produced by the 12- and 4-km MM5 grids. A primary contributor to MM5 ...
