Here we present multicentennial‐length and near annually‐resolved reconstructions of monsoon precipitation, inferred from absolute‐dated and instrumentally calibrated speleothem oxygen isotope records from regions (central and northeast India) that have diametric responses to active‐break monsoon circulation patterns. On centennial timescales (AD 1400–2008), precipitation variability from these two regions exhibit opposing behavior, oscillating between periods with a persistently “active‐dominated” (AD ∼1700 to 2007) and a “break‐dominated” (AD 1400 to ∼1700) regime. The switch between these regimes occurs abruptly (within decades) at a time (AD ∼ 1650–1700) when a proxy record of upwelling intensity from the Arabian Sea suggest an abrupt increase in the monsoon winds. On the basis of these observations, we hypothesize that the frequency distribution of active‐break periods varies on centennial timescales, implying a leading role of internal dynamics in governing the ISM response to slowly‐evolving changes in the external boundary conditions.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1384233270740955264","@type":"Researcher","foaf:name":[{"@value":"Ashish Sinha"}],"jpcoar:affiliationName":[{"@value":"Department of Earth Science California State University Dominguez Hills  Carson California USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1384233270740955267","@type":"Researcher","foaf:name":[{"@value":"Max Berkelhammer"}],"jpcoar:affiliationName":[{"@value":"Cooperative Institute for Research in Environmental Sciences University of Colorado at Boulder  Boulder Colorado USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1384233270740955268","@type":"Researcher","foaf:name":[{"@value":"Lowell Stott"}],"jpcoar:affiliationName":[{"@value":"Department of Earth Science University of Southern California  Los Angeles California USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1384233270740955266","@type":"Researcher","foaf:name":[{"@value":"Manfred Mudelsee"}],"jpcoar:affiliationName":[{"@value":"Climate Risk Analysis  Hanover Germany"},{"@value":"Alfred Wegener Institute for Polar and Marine Research  Bremerhaven Germany"}]},{"@id":"https://cir.nii.ac.jp/crid/1384233270740955392","@type":"Researcher","foaf:name":[{"@value":"Hai Cheng"}],"jpcoar:affiliationName":[{"@value":"Institute of Global Environmental Change Xi'an Jiaotong University  Xi'an China"},{"@value":"Department of Geology and Geophysics University of Minnesota  Minneapolis Minnesota USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1384233270740955265","@type":"Researcher","foaf:name":[{"@value":"Jayant Biswas"}],"jpcoar:affiliationName":[{"@value":"National Cave Research and Protection Organization  Raipur India"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00948276"},{"@type":"EISSN","@value":"19448007"}],"prism:publicationName":[{"@value":"Geophysical Research Letters"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"2011-08","prism:volume":"38","prism:number":"15","prism:startingPage":"L15703"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2F2011GL047713"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2011GL047713"}],"createdAt":"2011-08-04","modifiedAt":"2023-09-14","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050001202548679168","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Seasonal modulation of the Asian summer monsoon between the Medieval Warm Period and Little Ice Age: a multi model study"}]},{"@id":"https://cir.nii.ac.jp/crid/1360004240192164096","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"On the low-frequency component of the ENSO–Indian monsoon relationship: a paired proxy perspective"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285715169038208","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Decreasing Indian summer monsoon on the northern Indian sub-continent during the last 180 years: evidence from five tree-ring cellulose oxygen isotope chronologies"}]},{"@id":"https://cir.nii.ac.jp/crid/1360565166663048960","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"An Abrupt Shift in the Indian Monsoon 4000 Years Ago"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567180151480448","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Effects of intensification of the Indian Summer Monsoon on northern Andaman Sea sediments during the past 700 years"}]},{"@id":"https://cir.nii.ac.jp/crid/1361137045220882688","@type":"Article","resourceType":"preprint","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"On the low frequency component of the ENSO-Indian Monsoon relationship;
