SGI Supercomputers power mission-critical meteorological data

Navy Provides Mission-Critical Meteorological Data to U.S. Forces in Persian Gulf Generated by SGI Supercomputers

February 11, 2003

MOUNTAIN VIEW, Calif., Feb. 11 /PRNewswire-FirstCall/ -- A U.S. Navy weather center, powered by supercomputers from SGI (NYSE:SGI) , is providing U.S. military forces deployed in the Persian Gulf with highly accurate meteorological information critical to conducting land, sea and air operations. Should the United States go to war with Iraq, weather will have a major impact on how U.S. military operations are conducted in the region.

"Understanding the environment of the battlespace is critical to the success of U.S. military operations," said Dr. Richard Spinrad, technical director to the oceanographer of the Navy. "Meteorological and oceanographic conditions affect the safety and effectiveness of combat personnel, ships, aircraft and ground vehicles, as well as the performance of sophisticated sensor and weapon systems. Mission planners need accurate and timely environmental characterization to choose the right target, the right weapon, the right delivery system, the most effective tactics and even the best time for the strike. To do this requires a lot of data from remote and on-scene sensors, and a lot of computing power to analyze it."

The Fleet Numerical Meteorology and Oceanography Center, Monterey, Calif., is home to three SGI(R) supercomputers: a 512-processor SGI(R) Origin(R) 3800 server, a 128-processor SGI Origin 3800 server, and a 128-processor SGI(R) Origin(R) 2800 server. The combined computing power of these supercomputers has created one of the world's most sophisticated tools for global weather and ocean modeling, which taps into the largest existing real-time databases of oceanic and atmospheric observations.

Fleet Numerical operates 24 hours a day, 365 days per year and distributes meteorological information to military users around the world based on sophisticated global and regional meteorological and oceanographic models. For instance, the Navy's Coupled Ocean/Atmosphere Mesoscale Prediction System is used to predict changes in ocean and weather conditions in highly complex coastal areas of the world such as the Persian Gulf.

"Every day, U.S. military forces around the world depend on accurate weather forecasts generated by SGI supercomputers at Fleet Numerical to plan and carry out important missions, " said Mike Clancy, chief scientist, Fleet Numerical. "Our weather forecasting models result in about 500,000 daily oceanographic and atmospheric charts, analyses and forecasts, based on data gathered from satellites, ships buoys, and other weather and ocean sensor sources."

Weather conditions affect the successful deployment of a broad spectrum of U.S. weapons systems from ships to tanks to fighter planes:
