摘要：

Based on the NCEP/NCAR reanalysis data set, empirical orthogonal function analysis and correlation analysis have been carried out. Antarctic oscillation index (AOI) is defined as the difference between the zonal-mean monthly sea level pressure departures of 40 degrees S and 65 degrees S. Regional surface temperature and precipitation over the extratropical Southern Hemisphere have a close relationship with AOI.
