ABSTRACT
A system for operational multi-model evaluation was developed to investigate the behavior of surface circulation patterns in operational forecast oceanic models, focusing on the analysis of South Atlantic variability. The methodological approach consisted on the evaluation of operational simulations from five different oceanic circulation models: HYCOM/RTOFS-NCEP, HYCOM/GOFS-NRL, MERCATOR-OCEAN, POM/Tetra Tech and HYCOM/USP-Tetra Tech. Preliminary results are presented with the analysis of surface features, comparing model results against sea surface height anomalies, obtained from AVISO, and sea surface temperature, obtained from the GHRSST program. Available data from drifters and moored buoys were used for complementary comparisons, in terms of time series analyses. Differences in models’ configurations are discussed and consistency in forecast results is verified. The use of the multi-model evaluation tool is checked for operational applications.
