Long-term changes in thermal conditions on the surface of the Far-Eastern Seas and North-West Pacific and their relationship with large-scale climate processes

Previously published results of the study [Khen et al., 2019b] are continued. Long-term changes sea surface temperature (SST) in Far-Eastern Seas and North-West Pacific (NWP) described for 1950–2019 their relationship with large-scale climate processes by climatic indices (AO, Nino 3.4, PDO, ALPI, NPI, PNA, SHI, WP) is analyzed. SST has increased all seasons, higher rate winter autumn less significant trend summer. A prominent shift to warmer regime occurred Bering Sea 1977 that coincided a sharp change dynamics PNA indices. Such shifts were observed Okhotsk 1981 Japan 1990, one year after time-series AO, Smaller warming happened NWP 2008 2018. Decadal Oscillation main contributor variability though contribution ALPI variation considerable spring. Arctic most important Sea. Variations SHI WP Any single index does not determine NWP, seasons. The set can be divided into two categories: western eastern ones, according certain regions. group includes WP, which contribute mostly variations regions, westward from longitude Kamchatka. ALPI.
