| 摘 要： | 根据国家海洋局全部海洋站的水温和水位资料,以及“热带海洋和全球大气(TOGA)”的ADCP测流和CTD资料计算并分析了黑潮源流区输入西北太平洋的北向质量通量和西北太平洋及其邻近海域的水温、水位的异常变化,同时还应用美国宇航局Goddard地球观测系统(GEOS)/四维资料同化系统(DAS)计算并分析了西北太平洋的海面潜热通量的空间和时间变化.结果表明,北向质量通量具有明显的年际变化.这种年际变化与西北太平洋水温、水位和潜热通量的变化有着合理的因果关系.当前者减少时,后3者也明显减小.其物理解释是从热带西太平洋输入西北太平洋的海水质量和热量的减少将导致西北太平洋的减水和热量收入的减少,而热量收入的减少又将会引起水温和潜热通量的减小.

| Abstract: | Based on the data obtained from all the marine stations of State Oceanic Administration of China, and the ADCP and CTD data measured during "Tropical Ocean and Global Atmosphere (TOGA)", the northward flux of the sea water mass from the original sea-area of Kuroshio into the northwest Pacific Ocean (NWPO), and the water temperature and the sea surface level in NWPO and its adjacent seas are estimated and analyzed.In addition, the spacial and temporal variability of the latent heat flux through the sea surface of NWPO are estimated by use of the Goddard Earth Observing System(GEOS).It is shown from the results of the estimation that there is obvious interannual variability of the northward flux of the sea water mass.The relationship between this variability and the closely associated variabilities of water temperature, sea surface level, and the latent heat flux is the relationship between cause and effect.When the former one becomes decreased, the latter three will get obviously decreased.The physical explanation for the relationship between them is that the sea water mass and heat content transported from the western tropical Pacific Ocean into NWPO will make the water decrement and the total heat budget of NWPO decrease.Furthermore the heat budget decrease will in turn make the water temperature and the latent heat flux decrease. |
