The unprecedented absence  of TC formation is consistent with the extremely unfavorable large-scale conditions that are linked to an anomalous anticyclonic circulation over the WNP, which results mainly from sea surface temperature  (SST) anomalies across the tropical oceans. Numerical experiments suggest that the tropical Indian Ocean  SST anomalies, which were warmest in July 2020 since 1965, play a dominant role in the anomalous  WNP anticyclonic circulation, while the increased zonal SST gradient across the tropical Pacific and the  Atlantic SST warming also have important contributions. This study suggests that the configuration of SST anomalies across the tropical basins is quite important to the WNP TC activity.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"What caused the unprecedented absence of western North Pacific tropical cyclones in July 2020?","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-11 01:32:44.853372","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2023-02-07","DateCreate":"2021-05-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000675524000026","VABBcode":null,"OpenAcc":0,"Handle":"10.1029/2020gl092282"},"refs":null,"anarec":{"AnaID":336952,"PubliDate":2021,"Pagination":"e2020GL092282","XtraPublOfAnaID":null,"ISBN":null,"Volume":"48","Issue":"9","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42920,"SerRR":"Geophysical Research Letters.
