Although ocean salinity in the tropical Pacific (particularly in the western Pacific warm pool) can vary in response to El Ni&#x000F1;o events, its effect on ENSO evolution and forecasts of ENSO has been less explored. Here we present evidence that, in addition to the passive response, salinity variability may also play an active role in ENSO evolution, and thus important in forecasting El Ni&#x000F1;o events. By comparing two forecast experiments in which the interannually variability of salinity in the ocean initial states is either included or excluded, the salinity variability is shown to be essential to correctly forecast the 2007/08 La Ni&#x000F1;a starting from April 2007. With realistic salinity initial states, the tendency to decay of the subsurface cold condition during the spring and early summer 2007 was interrupted by positive salinity anomalies in the upper central Pacific, which working together with the Bjerknes positive feedback, contributed to the development of the La Ni&#x000F1;a event. Our study suggests that ENSO forecasts will benefit from more accurate salinity observations with large-scale spatial coverage.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Salinity anomaly as a trigger for ENSO events","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-13 01:31:21.947535","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2014,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2014-11-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000343983600012","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/srep06821"},"refs":null,"anarec":{"AnaID":242740,"PubliDate":2014,"Pagination":"5 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"4","Issue":" 6821","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
