However, whether abrupt climate changes intensified during past warm periods remains poorly constrained due to the lack of high- resolution geological records. Here, we report a 512- m predominantly lacustrine sedimentary record from the Weihe Basin (North China), revealing that lake levels fluctuated significantly on suborbital (half- and quarter- precession) and millennial timescales over the last 2 Ma. Grain- size results reveal that magnitudes of rapid lake level fluctuations increased dramatically during Pleistocene interglacials, differing from glacial amplification of abrupt climate events recorded in North Atlantic marine sediments. Model results indicate that summer insolation maxima in low- latitude region of both hemispheres can lead to intensified monsoon precipitation in East Asia. Our proxy- model comparison highlights the importance of low- latitude bihemispheric insolation maxima in driving millennial- scale hydroclimatic variability in a warming future.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Suborbital- and millennial- scale monsoon variability during Pleistocene interglacials","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-11-04 01:36:57.100969","timezone_type":1,"timezone":"+01:00"},"AuthorKeywords":"East Asian monsoon;Suborbital-and millennial-scale variability;Pleistocene interglacials;Low-latitude insolation forcing;el-nino/southern oscillation;climate variability;global monsoon;asian monsoon;indian-ocean;weihe basin;insolation;equatorial;pacific;record","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2026-09-28","DateCreate":"2026-09-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001510575100001","VABBcode":null,"OpenAcc":0,"DOI":"10.1073/pnas.2426353122"},"refs":null,"anarec":{"AnaID":449249,"PubliDate":2025,"Pagination":"e2426353122","XtraPublOfAnaID":null,"ISBN":null,"Volume":"122","Issue":"23","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43690,"SerRR":"Proceedings of the National Academy of Sciences of the United States of America.
