Environmental Modeling Center

The Environmental Modeling Center ( EMC ) improves numerical weather, marine and climate predictions at the National Center for Environmental Prediction (NCEP), through a broad program of research in data assimilation and modeling. In Support of the NCEP operational forecasting task, the EMC Develops, Improves and monitors data assimilation systems and models of the atmosphere, ocean and coupled system, using advanced methods Developed internally as well as cooperatively with scientists from Universities, NOAALaboratories and other government agencies , And the international scientific community.

History

In July 1954, the Joint Numerical Weather Prediction Unit (JNWPU) was created to test numerical weather prediction techniques by computer . Operational numerical weather prediction in the United States began in 1955 under the JNWPU. [1] This unit was co-located with the Weather Bureau-Air Force-Navy (WBAN), which was located in Suitland, Maryland . When the JNWPU was dissolved in 1961, NMC became an independent organization from the National Weather Center and the Fleet Numerical Weather Central . [2] Research and computer processing abilities Increased over the years, qui allowed for the first global forecast model to run by June 1966. [3] NMC Moved to the World Weather Building in Camp Springs, Maryland entre 1974 and 1976. NMC changed icts NCEP, the National Centers for Environmental Prediction on October 1, 1995, with the Environmental Modeling Center (EMC) becoming one of its subunits. EMC moved to the National Center for Weather and Climate Prediction building in September 2012. The National Centers for Environmental Prediction on October 1, 1995, with the Environmental Modeling Center (EMC) becoming one of its subunits. EMC moved to the National Center for Weather and Climate Prediction building in September 2012. The National Centers for Environmental Prediction on October 1, 1995, with the Environmental Modeling Center (EMC) becoming one of its subunits. EMC moved to the National Center for Weather and Climate Prediction building in September 2012.

Operations

The Environmental Modeling Center is responsible for the development, running, and maintenance of more than 20 numerical weather prediction systems including NCEP’s operational production suite. These models include the Rapid Refresh (RAP) , Global Forecast System (GFS) , the Global Ensemble Forecast System (GEFS) WaveWatch III , Short Range Ensemble Forecast (SREF), the NCEP Climate Forecast System (CFS), RTOFS, North American Mesoscale Model (NAM) , Hurricane Weather Research and Forecasting Model (HWRF) , and the Geophysical Fluid Dynamics Laboratory (GFDL) . [4]
