摘要

摘要: 本文在计算海潮对重力固体潮观测的影响时,把全球海域分成近区和远区两部分。其中近区采用格林函数数值积分法,在远区对g^N(日)采用卷积积分法,而对g^E(日)利用函数级数拟合全球海潮潮高的球函数展开法。最后计算了北京、兰州和拉萨的重力固体潮观测值的海潮改正。

Abstract: In this paper, the calculation methods of the effect of oceanic tides (M₂) on the gravity tidal observations are discussed. The global oceanic area is divided into two parts: the near area and the far area. In the near area, the numerical integration method with Green function is adopted. In the far one, convolution integration is used for the g^N (θ), while a spherical harmonic expansion in which the function series is fitted with the globel oceanic tide height is used for the g^E(θ). Finally, the corrections of the effect of oceanic tides on the gravity tidal observations in Beijing, Lanzhou and Lasa were calculated.
