FOR IMMEDIATE RELEASE

 

National Weather Service's Modernization Successful in Improving Science, Forecasts

   

WASHINGTON — The National Weather Service's program that modernized and restructured operations between 1989 and 2000 led to greater integration of science into weather service activities and was a success despite schedule and budget overruns, says a new report from the National Research Council.

 

The modernization and associated restructuring of the National Weather Service developed five major technologies to modernize its operations, costing approximately $4.5 billion.  The committee that wrote the report said that this investment was both needed and generally well-spent.  The implemented technologies were:

  • the Automated Surface Observing System, which replaced manual weather observations;
  • the Next Generation Weather Radar, a network of advanced Doppler radars that contributed to increased lead times in predicting severe weather events, such as tornadoes, hail, and flash floods;
  • a new series of satellites that provided improved, all-weather data for longer-term forecasting;
  • advanced computer systems that increased the computing power to support National Centers tenfold; and
  • the Advanced Weather Interactive Processing System, which allowed communication among forecast offices and distribution of centrally collected data as well as offered field forecasters access to the data provided by the other new technologies.

Overall, the modernization significantly increased the amount of data and information available to field forecasters, academia, the private sector, and the general public.  It also improved outreach and coordination with state and local government, emergency management, and communities; provided for more uniform radar coverage and surface observations across the U.S.; and dramatically enhanced forecast and warning products.  However, certain aspects of weather forecasts and warning still need improvement, the committee said.  For instance, the probability of detection and forecast lead times for tornadoes and flash floods grew after the modernization, but the ratios for false alarms have remained high.  In addition, the performance of hurricane track forecasts have seen gains, whereas hurricane intensity forecasts have not.

 

The budget, schedule, and technological issues encountered during the modernization reflected traditional challenges of large projects, such as shifting budget constraints and ambitious technology leaps, the committee found.  For example, during the early stages, there was insufficient communication between the organization's management at the national level and the field office managers and their staff.  However, the framework left in place allows and encourages the technology and work-force composition to continue to evolve.

 

The study was sponsored by the U.S. Department of Commerce.  The National Academy of Sciences, National Academy of Engineering, Institute of Medicine, and National Research Council make up the National Academies.  They are independent, nonprofit institutions that provide science, technology, and health policy advice under an 1863 congressional charter.  Panel members, who serve pro bono as volunteers, are chosen by the Academies for each study based on their expertise and experience and must satisfy the Academies' conflict-of-interest standards.  The resulting consensus reports undergo external peer review before completion.  For more information, visit http://national-academies.org/studycommitteprocess.pdf.  A panel roster follows.
