The Navy Global Environmental Model (NAVGEM) is a global numerical weather prediction computer simulation run by the United States Navy's Fleet Numerical Meteorology and Oceanography Center. [1] This mathematical model is run four times a day and produces weather forecasts . [ 2 ]
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 US Navy.
A wave model requires as initial conditions information describing the state of the sea. An analysis of the sea or ocean can be created through data assimilation, where observations such as buoy or satellite altimeter measurements are combined with a background guess from a previous forecast or climatology to create the best estimate of the ongoing conditions.
Along with the NWS's Global Forecast System (GFS), which runs out to 16 days, the ECMWF's Integrated Forecast System (IFS), which runs out 10 days, the US Naval Research Laboratory Navy Global Environmental Model (NAVGEM), which runs out eight days, the UK Met Office's Unified Model, which runs out to seven days, and Deutscher Wetterdienst's ...
The Navy Operational Global Atmospheric Prediction System (NOGAPS) is a global numerical weather prediction computer model run by the United States Navy's Fleet Numerical Meteorology and Oceanography Center. This mathematical model was run four times a day and produced weather forecasts. The NOGAPS was replaced by the NAVGEM in February 2013.
Within the United States National Weather Service (NWS), forecast weather maps began to be published by offices in New York City, San Francisco, and Honolulu for public use. North Atlantic forecasts were shifted from a closed United States Navy endeavor to a National Weather Service product suite via radiofacsimile in 1971, while northeast ...
