Antarctic Polar Front

The southern front of the Antarctic Circumpolar Current, also known as the antarctic convergence, that separates the Antarctic Zone in the south from the polar frontal zone in the north.
It is characterized by sea surface temperatures near 5°–6°C and a salinity minimum of 33.8– 34.0 psu produced by high rainfall.

The amount of precipitation of any type (including the liquid equivalent of frozen hydrometeors); usually taken as that amount measured by means of a rain gauge (thus a small, varying amount of direct condensation is included).
