摘　　要：基于高分辨率的ROMS模式,以黄海暖水舌作为黄海暖流的示性指标,采用了谱分析及相关分析的方法,分析了黄海暖流主轴东西向的摆动和暖水舌南北向的变动,结果表明:(1)黄海暖流暖水舌的南北向变动存在5 a左右的周期变化特征,与纬向风速、超前其1个月的纬向风速和超前其1个月的经向风速相关,风速大则前锋位置就北移;(2)黄海暖流主轴的东西向摆动存在6~7 a的周期变化特征,与超前其1个月的经向风速相关,风速大则主轴西移。Based on the high resolution ROMS model,the Yellow Sea Warm Water tongue is taken as an indicator to study the variability of Yellow Sea Warm Current(YSWC) by using the methods of the spectrum analysis and correlation analysis.The results show that:(1) There are obvious 5 years variability of the YSWC in the south-north shifting,which is well agree with the zonal and moridional wind variability.When the wind is strong,the YSWC will intrude deeply to the northern Yellow Sea.(2) There are obvious 6～7 years variability in the east-west shiftting of the YSWC axis,which is related to the moridional wind speed one month ahead of it.When the wind is strong,the axis moves westward.
