The AMRC is one of the primary archives of meteorological data from Antarctica and its surrounding geographic areas. [1] The Antarctic Meteorological Forecast Center (AMFC) at UW-Madison was devised during the same time as the founding of the AMRC as a provider of weather forecasts for research vessels operating in the vicinity of Antarctica.
Nearly all of Antarctica is covered by a sheet of ice that is, on average, at least 1,500 m (5,000 ft) thick. Antarctica contains 90% of the world's ice and more than 70% of its fresh water. If all the land-ice covering Antarctica were to melt — around 30 × 10 ^ 6 km 3 (7.2 × 10 ^ 6 cu mi) of ice — the seas would rise by over 60 m (200 ft ...
An alternative name for the ACC is the West Wind Drift. The ACC is the dominant circulation feature of the Southern Ocean and has a mean transport estimated at 100–150 Sverdrups (Sv, million m 3 /s), [ 1 ] or possibly even higher, [ 2 ] making it the largest ocean current.
The Antarctic Circumpolar Current (ACC), or the West Wind Drift, is an ocean current that flows from west to east around Antarctica. The ACC is the dominant circulation feature of the Southern Ocean and, at approximately 125 Sverdrups , the largest ocean current. [ 12 ]

The Antarctic Circumpolar Wave (ACW) is a coupled ocean/atmosphere wave that circles the Southern Ocean in approximately eight years at 6–8 cm/s (2.4–3.1 in/s). [1] Since it is a wave-2 phenomenon (there are two ridges and two troughs in a latitude circle ) at each fixed point in space a signal with a period of four years is seen. [ 2 ]
The latest data shows high temperatures in portions of East Antarctica – where the most abnormal conditions are ongoing – that are typically between minus 58 and minus 76 degrees Fahrenheit ...
