海潮负荷效应计算的精度估计

PRECISION ESTIMATION OF THE CALCULATION OF OCEAN LOADING EFFECTS (M2)

  • 摘要: 本文较系统地研究和讨论了海潮负荷效应计算的精度问题。建立了总的及单项的误差估算模型。对中国大陆M2波重力、倾斜和应变的负荷计算都给出了精度估值。结果表明,海潮负荷效应计算精度明显地受地球模型和海潮图精度的限制,尤其是地球模型选取不同,对结果影响更大。越靠近沿海,其相对精度越低。并对目前的负荷研究、改正精度等进行了分析和评价。

     

    Abstract: In this paper, we study and discuss the precision of the calculation of ocean loading effects (M2). Error models are developed for both synthetic and separated cases. The precisions are estimated of the calculation of ocean (M2) effects on gravity, tilt and strain in the China mainland. The results show that the precision are noticeably affected by the earth models and ocean maps, especially by the difference between the chosen earth models. The nearer to the ocean, the lower the relative precision. Finally, the present study of loading and the problem of correction precision are investigated and evaluated.
