Our results show that SST on the eastern margin of the South Atlantic followed the global cooling trend during the transition to MIS 4, while the western margin experienced warming during the same interval. We propose that the eastern-western thermal contrast observed in the first half of MIS 4 was caused by changes in the trade wind system. During the onset of MIS 4, a period of minimum Northern Hemisphere summer insolation led to an intensified trade wind zonal component and a weakened west African monsoon. This, in turn, strengthened the South Atlantic westward flowing currents, enhancing the transport of warm surface waters to the western margin. The intensified and more zonal southeastern trade winds increased eastern boundary upwelling, resulting in lower temperatures on the African margin. Our results highlight the importance of considering changes in the trade wind system in order to interpret the thermal responses of the South Atlantic during past glacial periods.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"369 ","pages":"Article 109613"},"PeriodicalIF":3.3,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145045442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Major-minor-trace element glass geochemistry and high-resolution radiocarbon chronologies were used to correlate cryptotephra deposits with known explosive eruptions at Reclus volcano (R1), Monte Burney and Hudson volcano (H2).
