| Abstract | The most important coupled ocean- atmosphere anomaly pattern is the El Nino Southern Oscillation (ENSO) of the tropical Pacific. The extratropical teleconnection to ENSO occur via preferred modes of the Rossby barotropic waves that are both zonally symmetric, and zonally asymmetric. They include the following: the Pacific-South America pattern of a standing wavenumber 3 anomaly; the Antarctic Circumpolar Wave, or a dominantly 2-wave pattern of coupled atmosphere-ocean-ice anomalies that migrate eastwards within the Antarctic Circumpolar Current (ACC); an eccentricity in zonal wavenumber 1 that occurs preferentially between the Australia and South America sectors; and the Antarctic Oscillation or zonal alternation of atmospheric mass between Antarctica and middle latitudes. The Article discusses mainly the ENSO teleconnection to the southern high latitudes and raises some unresolved issues. |
