NWS Raleigh Science Program
The purpose of the science program is to ensure that science and technology are used effectively in forecast and warning operations to fulfill the mission of the NWS. The utilization of science often requires research, many times with collaborative partners in NOAA, academia, and other members of the weather enterprise. Implementing science effectively requires frequent training with both atmospheric and hydrologic science as well as technology and software.
One of the country's strongest collaborative research relationships between a National Weather Service (NWS) office and a university started in Raleigh in the late 1970's. The process began when meteorologists from the NWS and NC State started collaborating on various projects including internships, seminars, and jointly participating in American Meteorological Society (AMS) meetings. The relationship grew during the 1980's and 1990's with projects such as the Genesis of Atlantic Lows Experiment, the Southeast Consortium on Severe Thunderstorms and Tornadoes, and various COMET projects. In 1994, the NWS office moved and became collocated with NC State University. In the following years, NWS Raleigh co-sponsored the first AMS regional workshop for operational forecasters and hosted a National Weather Association annual meeting. NWS Raleigh has participated in three NOAA Collaborative Science, Technology, and Applied Research (CSTAR) projects and nearly a dozen COMET projects. The office participates in several NC State meteorology courses, a student internship course for credit, and has hosted numerous student volunteers. Research and science results have been published in several journals, presented in countless conferences, and shared with other NWS offices.
A much more thorough and detailed History of the NWS Raleigh Science Program and Collaboration is available.
A power point presentation illustrating the collaboration & research success between the NWS Raleigh and North Carolina State University is also available.
For many years, the National Weather Service in Raleigh and North Carolina State University have worked together to improve forecast and warning services in the Carolinas. One result of these collaborative efforts has been a better understanding of forecast problems found in the southeast and has often resulted in operational schemes that have helped NWS meteorologists forecast these meteorological phenomena. In addition to the various research projects undertaken, the collaboration also allows students the opportunity to participate in formal internships, to work alongside forecasters, and to volunteer on various projects at the NWS office.

For many years, the National Weather Service in Raleigh and North Carolina State University have worked together to study forecast problems found in the southeast. One result of this collaborative relationship have been improved operational techniques that have helped NWS meteorologists forecast these meteorological phenomena.
The transition of Research into Operations, often referred to as R2O, is a critical part of this collaborative relationship. At times the relationship takes an O2R2O framework where operational meteorologists bring problems to the researcher's attention who in turn provide improved techniques to the meteorologists.
The joint collaborations, whether they are R2O or O2R2O, are viewed as a 5-Step Process, whereby research findings ultimately are integrated into operations.
A large part of the collaboration has been facilitated with grants to support several large projects including three NOAA Collaborative Science, Technology, and Applied Research (CSTAR) projects and nearly a dozen Cooperative Program for Operational Meteorology, Education and Training (COMET) projects.
The latest information on these or any collaborative project is located on the National Weather Service - NC State Collaborative Research & Training Site.

The NWS Raleigh has a long tradition of providing event summaries and case studies for significant and unique meteorological events. The event summaries, case studies, and event maps serve many purposes including: a means to improve our meteorological understanding, a summary of the event for use as a training tool, a means to evaluate the station's performance (determining the training needs of the station and for individuals), and a review of the event for general interest needs. Our inventory of cases is well over 140 and it continues to grow.
