In this paper the relationship between the interannual variations of East Asia winter monsoon and the El Nino events is examined based on the monthly mean sea level pressure (SLP) data set over the greater parts of the globe (50°S-60°N),and the sea surface tempereture (SST) in the Equatorial Eastern Pacific (0°-10°S,180°-90°W) from 1951 to 1986. The main results are as follows: (1) Significant correlations between the SST in the Equatorial Eastern Pacific and the SLP during predominating of the East Asia winter monsoon (Oct.-Mar.), | occur in southern Asia and western Pacific (positive correlation), northern Austra-l lia (positive correlation) and Aleutians Island (negative correlation). (2) The variations of the SST lead that of the SLP in one or two seasons. The greatst correlation is found between the SST in November and the SLP in the months preceded and followed. (3) In the winters (Dec. of 0 year to Feb. of 4- 1 year) of an El Nino year, the path of cold wave over East Asian continent migrates to the east in comparing; to the normal and the precipitations increase in South China. On the contrery, in an anti-El Nino year the path of cold wave moves to the west and the .precipitation decreasesin in South China.
