Based on oceanic and atmospheric parameters retrieved by satellite remote sensing using a neural network method, air-sea heat fluxes over the western Pacific warm pool area were calculated with the advanced the advanced Coupled Ocean-Atmosphere Response Experiment 3.0 (COARE3.0) bulk algorithm method. Then, the average annual and interannual characteristics of these fluxes were analyzed. The rela- tionship between the fluxes and the South China Sea (SCS) summer monsoon onset is highlighted. The results indicate that these fluxes have clear temporal and spatial characteristics. The sensible heat flux is at its maximum in the Kuroshio area, while the latent heat flux is at its maximum in the North Equatorial Current and Kuroshio area. The distribution of average annual air-sea heat fluxes shows that both sensible and latent heat fluxes are maximized in winter and minimized in summer. The air-sea heat fluxes have obvious interannual variations. Correlation analysis indicates a close lag-correlation between air-sea heat fluxes in the western Pacific warm pool area and at the SCS summer monsoon onset. The lagcorrelation can therefore predict the SCS summer monsoon onset, providing a reference for the study of precipitation related to the monsoon.
利用1958—2007年间的月平均SODA(Simple Ocean Data Assimilation/海洋同化数据)资料,较系统地研究了北太平洋经向盐量输送的基本特征和季节变化,并探讨了盐量输送季节变化的可能原因。结果表明,北太平洋净经向盐量输送的季节变化具有明显的区域性特征,在14°N以南海域盐量输送的季节变化较显著,而在14°N以北海域则较小;北太平洋净经向盐量输送的季节变化在很大程度上是由同一纬度上Ekman盐量输送和中东太平洋经向盐量输送的季节变化引起的。
