摘　　要：The article emphatically reviews the research progress in interconnections between the East Asian and Indian Ocean summer monsoons, between the Asian monsoon and the El Ni?o-South- ern Oscillation (ENSO) activity, and between the monsoon, ENSO and the changing of the North At- lantic climate during the Holocene. According to the studies of recent years, it is found that the intensity variations of the East Asian and Indian Ocean sum- mer monsoons show an opposite relationship, which may be closely related to the phenomena of ENSO in the equatorial Pacific Ocean and the variation of the deep-water formation of the North Atlantic Ocean on the interannual to orbital time scales. The 4k and 8k events occurring at around 4200 and 8200 a BP, re- spectively, might be the two in a series of severe pa- leo-El Ni?o events during the Holocene, strongly re- flecting the interactions and influences of the mon- soons, ENSO and the North Atlantic climate. In order to better understand the relationships between these paleoclimatic phenomena, scientists need to strengthen the research work on the Asian monsoon division and the comparison between monsoon proxy records, and the study on the proxy record of sea surface temperature with high time-resolution in the equatorial Pacific Ocean and the simulation research of paleoclimate condition.The article emphatically reviews the research progress in interconnections between the East Asian and Indian Ocean summer monsoons, between the Asian monsoon and the El NiSo-Southern Oscillation （ENSO） activity, and between the monsoon, ENSO and the changing of the North Atlantic climate during the Holocene.
