At this point the Subantarctic waters, which are characterized as being much warmer than the Antarctic waters, are just north of the Antarctic Polar Front and the Antarctic waters are just south of the Antarctic Polar Front.

This region is referred to as the Antarctic Convergence Zone / Antarctic Polar Front because of the sharp gradients in both temperature and salinity ( esp . temperature ) between the Antarctic waters and the Subantarctic waters.

Surveys of the SW Indian Ocean have shown phytoplankton group variation based on their location relative to the Polar Front, with diatoms dominating South of the front, and dinoflagellates and flagellates in higher populations North of the front.

The months of winter, mainly June and July, produce minimum temperatures between in the coastal regions, much lower in the plateau regions where temperatures of have been recorded in Chapada Diamantina after the passage of a polar front.

These major mountain ranges act as a barrier causing a strong rain shadow effect on the leeward side by dropping much of the humidity brought by atmospheric disturbances along the polar front which affects the surrounding Mediterranean climates.

As pointed out in a key paper by Jacob Bjerknes and Halvor Solberg ( 1895-1974 ) in 1922, the dynamics of the polar front, integrated with the cyclone model, provided the major mechanism for north-south heat transport in the atmosphere.

This location gives the region a typical Mediterranean climate with mild, wet winters caused by the outer edges of polar fronts, and warm to hot, dry summers, due to the domination of the subtropical high pressure systems, according to the K�ppen classification ( Csa / Csb ).

The Zonda wind is produced by the northeastward movement of polar fronts, and although is hot and dry at the low-lands, it is the main mechanism for snow precipitation at the high altitude chains, where it looks as " viento blanco ", reaching speeds sometimes over 200 km / h.

On the Hans Groeber crossection above ( Antarctic _ bottom _ water _ hg . png ), Subantarctic Surface Water is at the surface between the Antarctic Convergence ( labelled " Polar Front " ) and the Subtropical Front, with the Subantarctic Front as an unlabelled line separating nothing in particular.
