Then the Hadley circulation in the Eastern Hemisphere is weakened and that in the Western Hemisphere is enhanced, followed with the moment of momentum taken by its ascending branch increased in the Western Hemisphere while weakened in the Eastern Hemisphere. The PNA pattern is enhanced and the Pacific-East Asian teleconnection is weakened. As a result, the atmospheric circulation's response to the ENSO events in the Eastern Hemisphere is weakened and that in the Western Hemisphere is enhanced.

o事件使Walker环流减弱及其上升支东移的现象更明显，Hadley环流在东半球减弱而在西半球增强，由其上升支带至中纬的角动量在东半球减少，西半球增多，造成影响西半球大气环流的PNA型遥相关增强，影响东半球的太平洋-东亚型遥相关减弱，进而使得ENSO对东半球大气环流的影响减弱而对西半球大气环流的影响则有所增强。
