| 摘 要： | In this paper,climatic features of sea temperature of western Pacific warm pool and therelationship with sea surface temperature (SST) of its adjacent regions are analyzed based on theobserved sea temperature on vertical cross section along 137°E in western Pacific,the monthlymean SST of Xisha Station in South China Sea and the global monthly mean SST with resolution of1°×1°(U.K./GISST2.2).The results indicate that (1) in a sense of correlation.SST of westernPacific warm pool can represent its sea subsurface temperature from surface to 200 m-depth level inwinter,and it can only represent sea temperature from surface to 70 m depth in summer.The seasubsurface temperature anomaly of warm pool may be more suitable for representing thermalregime of western Pacific warm pool.The sea subsurface temperature of warm pool has acharacteristic of quasi-biennial oscillation.(2)Warm pool and Kuroshio current are subject todifferent ocean current systems (3)Furthermore,the relationship between SST of Xisha Stationand SST of warm pool has a characteristic of negative correlation in winter and positive correlationin summer,and a better lag negative correlation of SST of Xisha Station with sea subsurfacetemperature of warm pool exists.(4)Additionally,oscillation structure of sea temperature like “aseesaw” exists in between warm pool and Regions Nino3 and Nino4.January (June) maximum(minimum) sea subsurface temperature anomaly of warm pool may serve as a strong signal thatindicates maturity phase (development phase) of La Nina (El Nino) event,it also acts as a strongsignal which reveals variations of SST of Regions Nino3 and Nino4.
