Antarctic convergence

views updated May 08 2018

Antarctic convergence (AAC) 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 is now called the Antarctic polar front.
