Professor, Department of Meteorology
My research is centered on the observation and analysis of weather and climate processes in mountainous regions. I helped establish the NOAA Cooperative Institute for Regional Prediction in 1996 and currently serve as the Director of the Institute, which conducts a broad program of research aimed at improving weather and climate prediction in regions of complex terrain. The development and implementation of weather support for the 2002 Winter Olympics and Paralympics was a critical component of Institute activities from 1996-2002.
My current research activities include further development of MesoWest (see http://www.met.utah.edu), which provides access to surface weather observations for operational, research, and educational applications. MesoWest has evolved since 1996 from providing weather information at a few dozen weather stations in northern Utah using a handful of graphical displays to the current availability of weather conditions at thousands of stations around the nation using a state-of-the-art database and dozens of tabular and graphical displays. Specialized application software has been developed to support the fire weather community (see http://www.met.utah.edu/roman). The MesoWest observations also provide a foundation from which to conduct research to improve data assimilation techniques over complex terrain.
