基于内波动力学方程,提出利用TOPEX/Poseidon高度计资料提取内潮的方法.利用该方法,结合1992年10月到2002年6月共10 a的TOPEX/Poseidon高度计资料和Levitus(1998)资料,给出了整个太平洋M2内潮能通量的分布,并与观测资料进行比测,两者符合较好.同时也发现沿整个太平洋边界M2内潮能通量向大洋内部输入的总功率为58.4 GW,其中北太平洋对此贡献为30.2 GW,南太平洋为28.2 GW,可见南、北太平洋的贡献是基本相等的.东太平洋的总量为17.8 GW,而西太平洋为40.6 GW,两者差异较大(以160°W作为东、西太平洋分界线).
Based on the internal wave dynamic equation, a method of extracting internal tide based on the TOPEX / Poseidon altimeter data is proposed. By using this method, combining TOPEX / Poseidon altimeter data and Levitus (1998) data of 10 a from October 1992 to June 2002, The distribution of the M2 tide fluxes over the entire Pacific Ocean is measured and compared with the observed data, which is in good agreement with the conclusion that the total input of M2 tidal fluxes into the ocean along the entire Pacific boundary is 58.4 GW , Of which the contribution of the North Pacific to 30.2 GW and the South Pacific to 28.2 GW, showing that the contribution of the North and South Pacific is basically equal to the East Pacific totals 17.8 GW, while the Western Pacific is 40.6 GW, the difference between the two large (At 160 ° W for the East and West Pacific Divisions).
