Time series of the zero wind stress curl latitude and of the zonally averaged wind stress curl magnitude are used to drive volume transport in a linear, one-layer, quasi-geostrophic numerical model with a Drake Pasagelike gap. The wind stress curl time series, computed from observed winds and low-pass filtered to retain only seasonal time scales, are used to test the hypothesis that changes in the latitude of zero wind stress curl influence volume transport fluctuations through Drake Passage. Model results show that variations in the latitude of zero wind stress curl are coherent and in phase with model volume transport at periods greater than 30 days. When the time series of the latitude of zero wind stress curl are analyzed with transport acceleration both from the model and from Drake Passage observations, coherence squared between acceleration and the integrated wind stress curl are good. Both model experiments and Drake Passage field measurements suggest that variations in the latitude of zero wind stress curl are an important mechanism in modifying volume transport fluctuations in the Antarctic Circumpolar Current. ¿ American Geophysical Union 1989
