Abstract

This paper develops an initialization procedure for cold-starting the Semi-spectral Primitive Equation Model (SPEM) for one week forecasts in the Gulf Stream region. Six case studies during May 6-13-20, 1987, July 7-14-21, 1987, and May 4-11-18, 1988, are included in this study, and selected forecasts from these runs are discussed in depth. We develop the initialization procedure, and then discuss the known problems with the method. We discuss the evolution of the Gulf Stream region during these time periods and qualitatively compare our model results against data. We also show, using a quantitative measure of skill, that the model has forecast skill when compared with persistence. The initialization method discussed is general, physically consistent, and applicable to other ocean models.
