Real-Time Ocean Modeling Systems

Abstract

The first operational weather prediction occurred in May 1955 as a joint United States Air Force, Navy, and Weather Bureau project. In principle numerical ocean modeling is similar to atmospheric modeling, but global operational oceanography has lagged far behind (see the 'Atmospheric versus Oceanic Prediction' sidebar). This has been a concern for the U.S. Naval Research Laboratory; because, as a nation protected from adversaries and linked to partners by the world's great oceans, it is fundamental that the U.S. understand its surrounding marine environment. Consequently, for the past decade, the NRL has been working on the problem of eddy-resolving global ocean modeling and prediction. Further more, it has developed the world's first global ocean nowcast and forecast system using the Department of Defense's High Performance Computing Modernization Program (HPCMP) computing resources. It has been running in real time at the Naval Oceanographic Office (NAVO) since October 2000. Here, we describe the computational requirements of numerical ocean modeling and how the NRL system operates.
