[3] The Brazil Current is a part of the South Atlantic subtropical gyre.
The southern side of the gyre consists of the eastward-flowing South Atlantic Current (SAC).
[2] It is a western boundary current like the Gulf Stream, and is its southern counterpart; however, it is considerably shallower and weaker.
[2][5] The main transport of the current leaves the continental shelf at about 38˚S and the sea surface temperature at that latitude is estimated to be about 16–18˚C,[2][6] although the latitude where the current separates from the coast has been thought to be farther north from July to September than from January to March.
[8] The range of sea surface temperature and the salinity for the Brazil-Falkland Confluence is 7–18˚C and 33.6–36 psu.
