Surface drift in the South-East Atlantic Ocean

Surface drift in the South-East Atlantic Ocean is described using historica l shipdrift data. The Benguela Current has a width of 200 km in the south a nd 750 km in the north. The mean speeds of the current vary from < 11 cm.s( -1) to a maximum of 23 cm.s(-1). The highest current speeds occur during su mmer in the southern regions and during winter in the northern regions. and this seasonality corresponds well with seasonal wind speeds. Eddy kinetic energy is enhanced in the Subtropical Convergence zone and is highest in th e general vicinity of the Agulhas Current retroflection. The Subtropical Co nvergence is evident as a line where northward Ekman drift terminates.
