NOAA Cooperative Institute for Regional Prediction
Overview
Beginning with modest funding from the NWS/UCAR COMET program in 1991, faculty and students at the University of Utah began applied research in cooperation with forecasters at the Salt Lake City WFO and staff at the Scientific Services Division of the Western Region of the National Weather Service (NWS). Building upon the foundation provided by COMET, the NOAA Cooperative Institute for Regional Prediction (CIRP) was established by NOAA and the University of Utah in 1996 to conduct research that would lead to improvements in operational forecasts in regions of complex terrain. CIRP has contributed to improved knowledge of western U.S. meteorology, provided advanced training for operational meteorologists, and produced operational monitoring and prediction tools that benefit the public. Although the 2002 Winter Olympic Games served as an initial focal point for many CIRP activities, the ultimate goal for establishing CIRP and for CIRP’s participation in the Olympic support effort was to provide long-term benefits to the public and the atmospheric science community. The partnership of government, private sector, and academic groups assembled to provide weather support for the 2002 Olympic Winter Games contributed to one of the most successful Winter Olympics in history.
CIRP's annual budget of roughly $700,000, which is provided by the National Weather Service, National Science Foundation, Bureau of Land Management, Department of Energy and other agencies , supports the research, educational, and public service activities of two faculty (Horel and Steenburgh) and their 4 staff members, and 7 graduate students. NWS base funding for the next 3 years (2004-2007) has recently been awarded by the NWS through a competitive proposal process.
The mission of the Institute is to foster a broad research program aimed at improving weather and climate prediction in regions of complex terrain, with emphasis placed on weather and climate issues of the Great Basin, Colorado River Basin, and other regions of the western United States. The Institute has identified research objectives to be accomplished during the next 5 years that focus on the science priorities of the USWRP program. These objectives are intended to transfer improved scientific understanding and technological advancements to local forecast offices and National Centers. Institute objectives for the next 5 years include: (1) conduct basic and applied research on problems related to the interaction of atmospheric flows and complex terrain; (2) improve access to surface weather observations throughout the nation; (3) improve data assimilation in regions of complex terrain; and (4) improve numerical weather prediction over complex terrain.
Some of the highlights of CIRP activities include:
- MesoWest. MesoWest is a real-time cooperative mesonet data exchange that provides access to weather observations from more than 180 government, educational, and commercial data providers at over 6000 surface stations around the nation, with an emphasis upon the western United States. The Real-Time Observation Monitor and Analysis Network (ROMAN) web-page interface provides access to MesoWest observations for fire weather applications.
- Data assimilation in complex terrain. CIRP generates surface analyses of temperature, wind, relative humidity, and pressure by combining the MesoWest data with background fields provided by the NCEP RUC2 analysis. Improving data assimilation in complex terrain is the major focus of CIRP research activities for the next several years.
- Mesoscale modeling and predictability in complex terrain. A real-time version of the Penn State/NCAR Mesoscale Model version 5 (MM5) had been run routinely for several years. Our focus is now shifting towards testing the next generation WRF model.
- Cool-season precipitation processes and prediction. Basic research conducted at CIRP has produced conceptual models and forecast techniques that have improved the analysis and prediction of lake-effect and orographic storms.
- Field Programs. Interest in the forecast challenges and difficulty in simulating weather in complex terrain helped to foster the Intermountain Precipitation Experiment and Vertical Transport and Mixing Experiment field programs held during 2000 in northern Utah. Numerous scientific publications and improved understanding of orographic precipitation and air quality in urban basins will follow from these field programs.
- Annual Intermountain Workshops. CIRP sponsors annual Intermountain Weather Workshops that are attended by weather professionals from across the western United States.
- Publications. Over the past 3 years (2000-2003) CIRP scientists have disseminated research results to the wider community by authoring or co-authoring 18 publications in Weather and forecasting, Monthly Weather Review, Bulletin of the American Meteorological Society, and Journal of Applied Meteorology.
The Institute is housed administratively in the Department of Meteorology, which is part of the
College of Mines and Earth Sciences.
Professor John Horel is Director of the Institute.
