Validation of the Harvard Open Ocean Model in the Gulf-Stream Region.
Abstract
During this contract period work was carried out on the evaluation of the Harvard Gulf-Stream forecasting system (GULFCAST). This was a continuation of work carried out under Contract No. N00014-86-K-6002. The Gulfcast system was designed for nowcasts and forecasts of 1 duration. It consisted of a quasigeostrophic dynamical model, feature models for initialization and updating, and an observational base of Infrared SST frontal locations, Geosat altimetric data when available, and a weekly dedicated AXBT flight designed to maintain accuracy via critical in situ data input (Robinson et at., EOS, TOR, 70 (45) 1464-1473, 1989). for over two years of real time forecasting, the Geosat determined standard deviation of the forecast stream axis offset was about 30 km, comparable to the noise level of its determination (Glenn et at., JCG 96(C4) 7145-7166, 1991). The system correctly forecasts approximately 75 percent of ring birth and reabsorption events.
