Dynamical Evaluation of Ocean Models using the Gulf Stream as an Example
Abstract
Ocean models run with atmospheric forcing but without ocean data assimilation are useful in studies of ocean model dynamics and simulation skill. Models that give realistic simulations with accurate dynamics, when run without data assimilation, are essential for eddy-resolving ocean prediction because of the multiple roles that ocean models must play in ocean nowcasting and forecasting, including dynamical interpolation during data assimilation, representing sparsely observed subsurface ocean features from the mixed layer depth to abyssal currents, converting atmospheric forcing into ocean responses, imposing topographic and geometric constraints, performing ocean forecasts, and providing boundary and initial conditions to nested regional and coastal models. A wide range of ocean dynamics contribute to these different roles. Here we focus on evaluating the dynamics of mid-latitude ocean currents simulated by state-of-the- art, eddy-resolving ocean general circulation models (OGCMs) with high vertical resolution, using the Gulf Stream as an example.
