 note = {We investigated an influence of sea ice anomaly in the Pacific sector of the Southern Ocean upon large-scale atmospheric circulation using an Atmospheric General Circulation Model (AGCM). It is well known that Pacific South American (PSA) teleconnection pattern is induced by El Niño-Southern Oscillation (ENSO) over the Southern Hemisphere. Changes in zonal winds associated with the PSA pattern affect sea ice anomalies in the Amundsen-Bellingshausen Sea (Pacific sector) and the Weddell Sea (Atlantic sector) of the Southern Ocean, which is called Antarctic Dipole (ADP) pattern. Based on the ADP sea-ice anomalies, an AGCM simulation under the low sea-ice condition in the Pacific sector and Atlantic sector (Ice run) are conducted. Comparison of geopotential height at 500 hPa between the Ice run and NCEP/NCAR Reanalysis indicated that the sea ice condition in the Pacific sector enhances positive phase of PSA pattern anomalies over western part of the Southern Hemisphere., 第4回極域科学シンポジウム
