本文用最大熵方法并结合付氏分析方法分析了黄海中部海区(36°N,124°E)内波调查资料。分析表明该海区存在很强的温度密度跃层。根据对海流资料的分析得出潮汐频率的波动是正压的。从消除了正压潮流后的余流中得到0.049Cph的波动,由温度资料得到频率为0.0514Cph的波动,且发现它基本是斜压的,即为低频内波。该低频波动主要为最低模态朝西方向传播的惯性内波。本文阐明了惯性波的产生来自局地风应力的作用。
In this paper, the maximum-entropy method and the Fourier analysis method are used to analyze the data of the internal waves in the central Yellow Sea (36 ° N, 124 ° E). Analysis shows that there is a strong thermocline jump in the sea. According to the analysis of ocean current data, the tidal frequency fluctuation is positive pressure. The 0.049Cph fluctuation was obtained from the residual flow after eliminating the positive pressure tide. The temperature was found to have a frequency of 0.0514Cph and found to be mainly baroclinic, which was the low frequency internal wave. This low frequency fluctuation is mainly the inertial internal wave propagating in the west direction with the lowest mode. This paper illustrates the role of inertial waves from local wind stress.
