THE ANALYSIS OF THE RELATIONSHIP BETWEEN THE SUBSYSTEMS OF THE ASIAN SUMMER MONSOON

In this study,the relationship between the subsystems of Asian summer monsoon is analyzed using U.S.National Centers for Environmental Protection/National Center for Atmospheric Research reanalysis and Climate Prediction Center Merged Analysis of Precipitation monthly mean precipitation data.The results showed that there is significant correlation between the subsystems of Asian summer monsoon.The changes of intensity over the same period show that weak large-scale Asian monsoon,South-East Asia monsoon and South Asian monsoon are associated with strong East Asian monsoon and decreasing rainfall in related areas.Meanwhile the large-scale Asian monsoon is relatively strong,Southeast Asia and South Asia monsoons are relatively strong,and precipitation is increasing.While the South-East Asia monsoon is strong,the South Asia monsoon is weak and the rainfall of South Asia is decreasing,and vice versa.The various subsystems are still significantly correlated as shown from the intensity changes in different cycles.
