Here, we present a high-resolution continental record from southwestern China that demonstrates the importance of interhemispheric forcing in driving ISM variability at the glacial-interglacial time scale as well. Interglacial ISM maxima are dominated by an enhanced Indian low associated with global ice volume minima. In contrast, the glacial ISM reaches a minimum, and actually begins to increase, before global ice volume reaches a maximum. We attribute this early strengthening to an increased cross-equatorial pressure gradient derived from Southern Hemisphere high-latitude cooling. This mechanism explains much of the nonorbital scale variance in the Pleistocene ISM record.completedQuaternary geologyArabian SeaAsiaBrunhes ChronCenozoicChinaFar Eastglacial environmentHeqing BasinIndian OceanIndian summer monsooninterglacial environmentisotope ratiosisotopesLeg 117Matuyama ChronmonsoonsO-18/O-16Ocean Drilling ProgramODP Site 722oxygenpaleoclimatologypaleomagnetismpaleotemperatureQuaternarystable isotopesupper Cenozoicupper QuaternaryYunnan Chinaurn:org.iodp:exp:117urnlargerWorkCitationcampaignurn:org.iodp:exp:117:site:722urnlargerWorkCitationstudyurn:org.iodp:exp:117urnlargerWorkCitationcampaignEnglishgeoscientificInformation59.4745100.101416.371826.4343application/pdfunknownSEDIS Publication Catalogue
