Short summary
An analysis of observed transports in the Brazil Current shows a factor 9 increase between its origin and terminus. The 23-year time series reveals an annual cycle with a maximum in austral summer whose significance decreases on the way south and varies interannually. In addition, 2–4-year long phases with relatively high/low values are observed. A correlation of the transport with the Southern Annular Mode (Niño 3.4 index), with a lag of 6 (8) months, is present at 24° S.
