Thor models global weather patterns and provides individual air bases and army units with specific forecasts for areas as small as 17 square kilometers. The computer system is comprised of nearly 1,000 individual blade servers. Thor’s increased capacity allows weather Airmen at Offutt to generate initial conditions and process them. Locally produced baseline data, combined with Thor’s increased processing speed, results in forecasts reaching the warfighter in half the time. This gives forecasters and mission planners up to three extra hours to exploit forecasts.
