摘要
使用NCEP/NCAR再分析资料和CMAP月平均降水资料分析了亚洲夏季风各个子系统的相互关系。结果表明亚洲夏季风子系统之间存在显著相关。从同期强度变化可知,当东亚季风偏强时,大尺度亚洲季风、东南亚季风、南亚季风均偏弱,相关区域降水偏少;而同时大尺度亚洲季风偏强时,东南亚和南亚季风偏强,相关区域降水偏多;东南亚季风偏强时,南亚季风偏弱,南亚地区降水偏少;反之亦然。从不同周期强度变化可知各个子系统相关仍然显著。
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.
