THE EFFECT OF OCEANIC TIDES (M2)ON THE GRAVITY TIDAL OBSERVATIONS

  • 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gN(日)采用卷积积分法,而对gE(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 gN (θ), while a spherical harmonic expansion in which the function series is fitted with the globel oceanic tide height is used for the gE(θ). Finally, the corrections of the effect of oceanic tides on the gravity tidal observations in Beijing, Lanzhou and Lasa were calculated.
