National Centers for Environmental Prediction (NCEP)
The National Centers for Environmental Prediction (NCEP) determine data requirements, optimum data processing techniques, and suitable presentation methods for predictions and products distributed to users of climatic, hydrologic, meteorological, space weather, and oceanographic information. NCEP Centers produce these products for distribution to field forecast offices of NWS, Air Force, Navy, Federal Aviation Administration, and other government and non-government users; produce for distribution to foreign meteorological centers products required of the World Weather Center; and produce extended and medium range forecasts and guidance, and develop methods and techniques for their improvement. NCEP Centers analyze and project short-term climate fluctuations on a regional and worldwide basis; identify significant climate anomalies and provide current information on them to users coping with associated climate problems, such as energy, food supply, water resources, and health. NCEP Centers maintain a continuous weather watch for thunderstorm activity, and prepare and disseminate severe local storm watches for protection of life and property; maintain a continuous weather watch in order to prepare and disseminate advisories of hazardous weather for aviation interests; and maintain a continuous weather watch for tropical cyclones on the Atlantic and Pacific Oceans, the Caribbean Sea, and the Gulf of Mexico; and prepare hurricane watches and warnings for the general public, and hurricane advisories for other marine, aviation, and military uses. NCEP Centers develop and produce oceanographic products and guidance; provide weather support for special aerospace and satellite operations; perform research and development to improve its climatic, hydrologic, meteorological, space weather, and oceanographic products; and develop plans and provide direction for improving products, and advise the Assistant Administrator of new capabilities resulting from new techniques or procedures.
