【摘要】 利用了多年连续的冬季水文调查数据,以黄海暖水舌作为黄海暖流的示性指标,采用经验函数正交分解及相关分析的方法,探讨了黄海暖流的年际变化特征,结果表明:1)黄海暖流的强弱存在4～7a的年际变化周期,并与冬季局地季风的经向分量具有较好的相关关系;2)黄海暖流的流轴存在一个3～6a的变化周期,而且其流轴的摆动明显受冬季季风纬向分量的影响;3)季风增强,黄海暖流增强且流轴西移。更多还原

【Abstract】 Based on multi-years,continuous hydrographic survey data for indicating the Yellow Sea Warm Current(YSWC)which is identified with the Yellow Sea Warm water tongue,the YSWC interannual variation is studied by means of the methods of Empirical Orthogonal Functions(EOF)and correlation analysis.The results show that(1)the YSWC strength obviously has an interannul variation of 4~7 years period,being well corretated to the longitudinal component of winter monsoon,(2)the YSWC path has a 3～7 years period,obviously influenced by the latitudinal component of winter monsoon,and(3)when the winter monsoon strenthens,YSWC becomes stronger and its path shifts westward.更多还原
