摘要
采用南海内波的实测资料,利用EMD方法对内波波动进行水平和垂向的分解,并由低频模态拟合函数并叠加得到了内波引起的温度波动的函数,由垂向位移得到了内波垂向模态的一种获取方法,为非线性的海洋内波研究提供了依据。
The internal wave data in the south sea are used to decompose the internal in horizontal and vertical by using the EMD method.A function of temperature fluctuations and a method to get the vertical mode functions are got,foundation of studying internal waves is provided.
