| Abstract: | In this paper, the characteristics of change in the
Antarctic sea ice area are analysed by using the observed data from 1973 1986. The
analysed 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. |
