The Potential for Ocean Prediction and the Role of Altimeter Data
Abstract
A skillful ocean forecasting capability will depend on adequate data input and computing power, and properly designed and adequately validated ocean models for data assimilation and forecasting . Once these conditions are satisfied, forecasts of meandering currents and eddies up to a few months appear to be a reasonable expectation. Simulation studies suggest that prediction of meandering currents and eddies requires high horizontal resolution. High vertical resolution can be obtained by using the circulation model to provide horizontal and vertical advection to a grid of one-dimensional mixed-layer models. Circulation models on subdomains of major ocean basins with extensive open ocean boundaries require accurate boundary information at all levels in the vertical and for the duration of forecasts longer than a few days. Basin-scale models appear to be the most promising source for this information. To provide useful boundary conditions, the basin-scale models must also resolve the meandering currents and eddies. Class 7 computers approx. expected on the market in the mid to late 1980s, are required for eddy-solving models of major ocean basins.
