In this paper, the characteristics of change in the Antarctic sea ice area are analyzed by using the observed data from 1973 - 1986. The analyzed results show that the monthly and annual change of the Antarctic sea ice area is obvious, the biggest change value is in 160°E - 120°W and 60°W - 100°E, the smallest value is in 110°E - 160°E and 120°W - 60°W. The relation between the Antarctic sea ice area and the Sea Surface Temperature (SST) in tropical Pacific is close, and the relation between the Antarctic sea ice area in each longitude belt and SST in tropical Pacific shows a clear difference. It is obvious that the Antarctic sea ice areas in 0°- 90°E and 100°E - 110°W have a different feedbacking relation with SST in the tropical Pacific. The notable relationship occurs in the 3 - 4 and 41 - 45 months, that quite tallies with the occurrence of El Nino
