Towards a High-Resolution Global Coupled Navy Prediction System
Abstract
A computational project is underway to bring about the realization of a high-resolution global coupled atmosphere/ocean/ice prediction system for Navy meteorological and oceanographic forecasting. A fully coupled near-global ocean/atmosphere prediction system has been constructed using resolutions of 0.75 degrees in the atmosphere and 0.5 degrees in the ocean (eddy-permitting) at the Naval Research Laboratory at Monterey (NRL-MRY). The system consists of the Navy Operational Global Atmospheric System (NOGAPS) that incorporates the NRL Atmospheric Variational Data Assimilation Scheme (NAVDAS), the Los Alamos National Laboratory Parallel Ocean Program (POP), and the Navy Coupled Ocean Data Assimilation (NCODA), an optimal interpolation scheme. The next steps in the development of this system are the inclusion of ice, improving the data assimilation scheme, and moving to higher resolution; fulfillment of these goals is being advanced by university and national laboratory partners. An eddy-permitting fully global coupled ocean/ice simulation is underway using POP and the Los Alamos sea ice model known as CICE.
