Data Center Description
National Centers for Environmental Prediction (NCEP)

The National Centers for Environmental Prediction (NCEP), an arm
of the NOAA's National Weather Service (NWS), is comprised of
nine distinct Centers, and the Office of the Director, which
provide a wide variety of national and international weather
guidance products to National Weather Service field offices,
government agencies, emergency managers, private sector
meteorologists, and meteorological organizations and societies
throughout the world. NCEP is a critical national resource in
national and global weather prediction. NCEP is the starting
point for nearly all weather forecasts in the United States.

The Office of the Director is responsible for directing and
planning the science, technology and operations of the following
National Centers:

The Aviation Weather Center provides aviation warnings and
forecasts of hazardous flight conditions at all levels within
domestic and international air space.

The Climate Prediction Center monitors and forecasts short-term
climate fluctuations and provides guidance information on the
long-term global effects climate patterns can have on the

The Environmental Modeling Center develops and improves
numerical weather, climate, hydrological and oceanic predictions
through programs of applied research in data analysis, modeling
and product development in partnership with the broader research

The Hydrometeorological Prediction Center provides analysis and
forecast products, specializing in quantitative precipitation
forecasts to five days, weather forecast guidance to seven days,
real-time weather model diagnostics discussions and surface
pressure and frontal analyses.

The Marine Prediction Center issues weather warnings and
forecasts out to five days, in graphic, text and voice formats
for the Atlantic and Pacific Oceans.

The NCEP Central Operations sustains and executes the
operational suite of the numerical analysis and forecast models
and prepares NCEP products for dissemination. It also links all
nine of the national Centers together via computer and
communications-related services.

The Space Environment Center provides space weather alerts and
warnings for disturbances that can affect people and equipment
working in space and on earth.

The Storm Prediction Center provides tornado and severe weather
watches for the contiguous United States along with a suite of
hazardous weather forecasts, mesoscale guidance products and a
continuous watch on mesoscale atmospheric processes.

The Tropical Prediction Center provides official NWS forecasts
of the movement and strength of tropical weather systems and
issues the appropriate watches and warnings for the US and
surrounding areas. It also issues a suite of marine products
covering the tropical Atlantic and eastern Pacific.
