This paper will present the results of an assessment of the impacts of COMET Cooperative and Partners collaborative research projects on NWS performance metrics for tornado, severe thunderstorm, flash flood and winter storm warnings. The study evaluated relevant collaborative projects within the Eastern Region of the NWS completed between 1995 and 2001. In addition, the verification trends at WFO Raleigh, NC will be examined to evaluate the influence of long-term collaborative activities on performance. WFO Raleigh has been continuously involved in collaborative projects with North Carolina State University since January 1991.
There are many factors that influence warning program verification scores on the long-term (e.g., technology infusion; implementation of applied research results, etc.) and the short-term (weather “regime” impacts on event types and frequencies; office staffing issues; etc.). This paper will describe how the assessment methodology attempted to isolate, to the extent possible, the impacts of the collaborative projects from these other factors.
