Correlation Analysis of East Asia Summer Monsoon Circulation Anomaly Index and Land-Sea Temperature Difference

Using 0.8 m monthly soil temperature over China and NCAR sea surface temperature data, the land\|sea temperature difference of China with the East Asia summer monsoon circulation anomaly index were analyzed initially. The correlation analysis between the East Asia summer monsoon circulation anomaly index and the land\|sea temperature difference is notable. And there is distinguished heterogeneity of temporal\|spatial distribution of annual variation trend, the distinguished differences exist in correlation distribution in various area. Dynamic analysis further proved the effect of the land\|sea temperature contrast on the East Asia Summer monsoon.
