Abstract: The relationship between different seasonal precipitations and sea surface temperature(SST) in southeastern Guizhou was analyzed by the correlation analysis method.The results indicated that the time and the correlation between SST of different regions and precipitations of different seasons were obviously different.SST in the Indian Ocean B area and NINO W area influenced remarkably precipitation in southeastern Guizhou in most seasons.SST in the eastern and central Pacific Ocean was related obviously with precipitation in autumn and winter.The correlations between precipitation in spring and winter and SST in the Indian Ocean B area and NINO W area were significant.Precipitation in summer and SST in Japan Current A area correlated remarkably.And precipitation in autumn and SST in the eastern and central Pacific Ocean and NINO 3.4 area as well as in NINO synthesis area correlated remarkably.ENSO warm event had close relationships with its occurring year winter precipitation,its ending year autumn and winter precipitation,the next year spring and summer precipitation of its ending year,while ENSO cold event was with its occurring year winter precipitation and its ending year autumn precipitation.
