FIG. 8. Total volume transport of the dominant (‘‘1’’) and subordinate (‘‘V’’) meridional overturning cells as a function of QS (in units of 1026 psu cm s21, which roughly corresponds to cm yr21 of surface freshwater flux) for (a) kH 5 5000 m2 s21, (b) DT 5 308C, and (c) DT 5 38C experiments. Each dashed line connects an experiment to the experiment that is used as an initial condition (initial condition runs were generally at higher QS than succeeding runs). Solid lines show values for runs in which QS is changed continuously during the run. The S-dom experiments are not shown. In (b), the highest QS experiment data is based on a time-average of the oscillating series.
