An Evaluation of High-Resolution Modeling and Statistical
AN EVALUATION OF HIGH-RESOLUTION MODELING AND STATISTICAL FORECAST TECHNIQUES OVER COMPLEX TERRAIN by Kenneth Alan Hart A dissertation submitted to the faculty of The University of Utah in partial fulfillment of the requirements for the degree of Doctor of Philosophy Department of Meteorology The University of Utah August 2004 Copyright © Kenneth Alan Hart 2004 All Rights Reserved ABSTRACT The accuracy of weather forecasts produced during the 2002 Olympic and Paralympic Games (23 Jan – 25 Mar 2002) by a multiply nested version of the PSU- NCAR Mesoscale Model (MM5) and associated model output statistics (MOS) system is evaluated using observations collected by the MesoWest cooperative network. Using traditional verification measures, the accuracy of MM5 wind and precipitation forecasts improved as model grid spacing decreased from 12 to 4 km. In contrast, temperature forecasts did not improve with decreasing model grid spacing due to the inability of the MM5 to properly simulate the evolution of persistent or nocturnal cold pools over lowland regions. Improved parameterization of the stable boundary layer processes may enable model skill to improve as grid spacing is decreased from 12 to 4 km. The need to improve model physics was also illustrated by the fact that MM5 MOS temperature, relative humidity, wind speed, and wind direction forecasts were considerably more accurate than those produced by either the 12- or 4-km MM5. These results suggest that, contrary to studies in regions of broader topographic features, decreasing model grid spacing (< 10 km) does improve model skill over the finescale topography of the Intermountain West. These improvements may be valuable for a variety of environmental applications including fire weather forecasting, air quality prediction, and transport and dispersion modeling. -

GOULD DISTINGUISHED LECTURE ON SCIENCE AND THE QUALITY OF LIFE Drought Happens, Get Used To It! Will Technology Help Us To Survive? by David W. Eckhoff Vice President & Regional Manager PSOMAS William R. and Erlyn J. Gould Auditorium J. Willard Marriott Library University of Utah Salt Lake City, Utah September 10, 2002 About the Gould Endowment y T T-illiam R. and Erlyn J. \/\/ Gould established an V V endowment in their names in 1992 in support of the activities conducted within the Utah Science, Engineering, and Medical Archives of the J. Willard Marriott Library. In addition to supporting the archives, the endowment also funds the annual William R. and Erlyn J. Gould Distinguished Lecture on Technology and the Quality of Life. These annual lectures focus on technical and environmental topics, and how they relate to society as a Erlyn and William Gould whole. William R. Gould, one of the world's leading engineers, businessmen, and entrepreneurs, has named the Marriott Library as repository of record for his professional and personal papers spanning more than forty years. As with many of the donors of collections housed in the Utah Science Archives, extensive oral history interviews have been conducted with Mr. Gould, as a supplement to his collection. Through support by the Gould Endowment of the Gould Distinguished Lecture series, William and Erlyn have expressed their desire to share with the public their hope for the future: that through a more complete understanding of technology and its application, perhaps the humanity of which we are all a part may find a stronger path to greater social potential.
