%X The correlations between the sea surface temperature (SST) of the Pacific and Indian Oceans and the global land surface temperature (LST) and the summer rainfall over the eastern China respectively are studied in this paper. Results show: (1) The positive correlation between the SST of Kuroshio area and the summer rainfall over the Yangtze River valley is apparent. There are obvious negative correlation between the summer rainfall over North China and the SST of Indian Ocean near Fast Africa coast. (2) The relationship between the variances of the summer rainfall over China and the global SST is also investigated by the singular value decomposition (SVD) analysis. There is an apparent trend with a regime shift (SVDI) of overall anomalies in the late 1970s in both SST and rainfall variations. It is evolved from negative to positive rainfall anomalies over the Yangtze River valley, and opposite to its north and south, when SST was developed from dominated by La Nina events to dominated by El Nino events. (3) There are the obvious correlation regions between the regional rainfall of the eastern China and LST. a) The evident positive correlations between the summer rainfall over the Yangtze River valley and LST cover the tropic Africa in spring and summer, and the partial Asian continent in summer. b) The clear negative correlation between the summer rainfall over the northern China and the partial Asian LST is showed in April and May. (4) The findings by comparison, contrast and analysis are that the common underlying surface conditions of the anomalously heavy rainfall over the Yangtze River valley (1954, 1998 and 1999) or the Changjiang-Huaihe (1991) valley are the positive departure of SST in the Kuroshio area and the mostly positive anomaly of LST over Eurasia.
