The ocean circulation is driven by a combination of winds and surface buoyancy fluxes. We run a number of experiments with varied surface forcings and look at the spatial variations in ocean circulation on short and long time-scales.
The idea is to remove time-mean wind stress and input only the temporal fluctuations. It is believed that the ocean gyres receive momentum input from the mean wind stress. A contradictory theory (refer Chris Bull's paper) highlights the role of wind variability in determining the strength of western boundary currents in ocean gyres.
