Antarctic polar front
Antarctic polar front A convergence line in the seas that circle Antarctica between latitudes 50°S and 60°S. It is where the cold waters from the Antarctic region meet and sink beneath the warm waters from the middle latitudes, so forming the
Antarctic intermediate water. This convergence line was formerly known as the Antarctic convergence (AAC).
