Comparison of Gulf Stream Forecast Model Initialization and Verification Analyses
Abstract
The preparation of two-week duration case studies for the initialization and verification of Gulf Stream forecast models was begun jointly by Harvard and NOARL in 1988. The six case studies were chosen by determining which time periods had both the REX GEOSAT underflight AXBT surveys and good IR coverage. The data was used to generate Gulf Stream axis location and the warm and cold ring locations spaced at one-week intervals. The analysis domain extended from approximately 74W to 54W. The strength of the total data set is that coverage by any single data set in this region is patchy. After preliminary tests, it was decided that additional data was needed to better locate the Stream axis. It was also necessary to add error bars on the frontal analysis. Preliminary comparisons of the NOARL and Harvard analyses indicated that, although some analyses agreed quite well, others were very different. INO wanted to use these data sets, but when differences were observed, INO sponsored the working meeting documented in this report, where these differences were either resolved, or when they lay within the error bars, so noted.
