Over the East Asia-West Pacific region, some meteorological factors are studied by using statistical diagnostic methods such as empirical orthogonal function (EOF) analysis, composite analysis and other statistical diagnosis. The results show an obvious opposite correlation exists between zonal dipole oscillation mode (APD) index and East Asian Pattern (EAP) index with a correlation coefficient of -0.23. Both APD and EAP indexes are closely correlated with precipitation during flood-prone season in China and precipitation rate over the East Asia-West Pacific region. The significant correlation area at 5% confidence level is mainly located from the southern area of the Yangtze River valley to the ocean around southern Japan, and the former is a positive correlation and the latter is a negative one
