Fleet Numerical Meteorology and Oceanography Center

Fleet Numerical Meteorology and Oceanography Center (FNMOC) provides the highest quality, most relevant and timely worldwide meteorological and oceanographic support, to U.S. and coalition forces, based out of Monterey, California and Stennis Space Center, Mississippi. FNMOC produces and disseminates assured meteorological and oceanographic products and services that enable fleet safety and the effective exploitation of the predicted environment.
FNMOC provides Global and Regional Weather Prediction Charts (WXMAP) and Global Ensemble Weather Prediction Charts (EFS). WxMAP depictions of NAVGEM predictions for side-by-side comparison with NCEP global NWS models (GFS) are also available. FNMOC provides Global and Regional Ocean Wave Prediction Charts (WW3), Global Ensemble Ocean Wave Prediction Charts (WW3 Ensemble), and Global Sea Surface Temperature and Sea Surface Anomaly Charts (NCODA). FNMOC provides links to satellite imagery of tropical cyclones (TCWEB) and current tropical storm forecast tracks.
FNMOC is composed of military and civilian personnel. The team consists of specialists in meteorology, oceanography, computer science, and Fleet operations. The team's efforts provide computerized weather and ocean prediction products, weather satellite imagery products, and related tactical decision aids and data, supporting virtually every combat platform and weapons system operated by the U.S. Navy.
History.
In 1958, the Navy Numerical Weather Problems (NANWEP) group was established in Suitland, MD. NANWEP was later moved to Naval Postgraduate School (NPS) in 1959. Fleet Numerical Weather Facility was established in 1961. In 1974, Fleet Numerical Weather Facility moved from NPS to its current location. In 1993, the current title Fleet Numerical Meteorology and Oceanography Center (FNMOC) was adopted. In 2005, Fleet Numerical was realigned under Naval Meteorology and Oceanography Command (NMOC). In 2011, Fleet Numerical completed a new Computer Operations Center.
FNMOC is one of the DoD's primary central production site for worldwide computer-generated operational meteorological and oceanographic analysis and forecast products.
Organization.
FNMOC is an echelon IV command aligned under the Naval Meteorology and Oceanography Command (COMNAVMETOCCOM) or CNMOC. FNMOC is co-located with Naval Research Laboratory (NRL) Marine Meteorology Division, a representation of successful transition of research into operations. FNMOC maintains close ties with the nearby Naval Postgraduate School (NPS).
Numerical Weather Prediction.
Central to FNMOC modeling capability is a global numerical weather model called the Navy Global Environmental Model (NAVGEM) and a global ocean prediction model called the Hybrid Coordinate Ocean Model (HYCOM). FNMOC models a variety of global, regional, sub-regional areas and specialized ocean and atmospheric environments as the DOD's premier Numerical Weather Prediction Center.
