Estimation of bottom friction coefficient for a 2 - d nonlinear tidal model of the bohai sea by the adjoint method 利用伴随同化方法估计渤海潮汐模式的底摩擦系数
Following the launch of topex / poseidon in 1992 , there has been considerable improvement in the accuracy of the global tidal models Topex / poseidon的发射极大地促进了大洋潮汐模型研究的进展,但大洋模型在浅海区域精度比较差。
The main task of this dissertation is to establish a three - dimensional numerical tidal model based on the three - dimensional tidal governing equations . by comparing the case studies with analytical solution , the accuracy of the model has been verified 本文的主要工作是从三维潮流控制方程出发,建立了一个三维潮流数值模型,通过对有解析解情况的模拟,验证了模型的合理性。
Firstly , a 1 - d flow numerical model based on the preissmann scheme , a 1 - d rivernet flow numerical model based on the direct solution method and a 2 - d tidal model based on the implicit scheme of finite difference method are programmed 本文首先建立了基于preissmann算法的一维水流模型、基于直接解法的平原河网模型和基于有限节点法的平面二维水力模型,在对各模型的算法进行推导的基础上自行开发了计算程序。
This method is better than the traditional method that relates the divergence of sediment transport rate to the deposition rate . the output of the tidal modelling reaches the required precision according to a comparison between the calculated tidal amplitudes / phases and the observed ones at 42 coastal tide gauge stations 潮汐潮流的模拟计算结果与沿岸42个潮汐测站的实测值结果对比达到了精度的要求,同时,计算得到的各分潮同潮图与实测结果相符。
Based on systematical study of each constituent of iss , the foundation , computation and precision analysis of the models of geoid , sea surface topography , mean sea surface and ocean tide are mainly discussed ; the conceive of mean sea surface height model and ocean tidal model suitable to chinese near sea and its neighborhood is provided ; two kinds of iss model are derived out 本文在系统研究瞬时海面高各组成要素的基础上,主要讨论了大地水准面模型、海面地形模型、平均海平面模型和海洋潮汐模型的建立、计算以及精度评价等问题;提出了建立适于我国近海及邻域平均海平面模型和海洋潮汐模型的设想;综合得出了两种瞬时海面高模型,并进行了精度估计,编制了相应的软件。
Based on the review of recent advances in surveying and controlling techniques of river models , described in this paper is a new controlling technique , which makes use of a two - way axial - flow pump and a immersion pump to control the up - boundary condition of discharge and the down - boundary condition of water level respectively , with the tidal model of the huangpu river estuary as an example 在对河工模型量测与控制技术进行回顾的基础上,以黄浦江河口潮汐河工物理模型为例,介绍了潮流河段上边界采用轴流泵进行双向流量控制、下边界采用潜水泵进行水位控制的新技术。
Though adopting the - coordinate transformation in the control equations and mode - splitting technique , the external mode ( surface gravity waves ) is solved by the improved double - sweep - implicit finite difference method ; the internal mode ( internal gravity waves ) untilizes the eulerian - lagrangian method , which improves the implicit - difference scheme for the vertical direction . the newly developed 3d numerical tidal model with implicit scheme has been successfully applied in the radial sandbanks area 基于过程分裂法及垂向坐标伸缩变换,外模式采用改进型双步全隐有限差分dsi法,内模式采用欧拉?拉格朗日公式,改进了三维垂向隐式格式,成功地建立了南黄海辐射状沙脊群海域三维全隐格式潮流数学模型。
However , the application of global tidal model to the study of shallow sea tides is much worse in the accuracy . tidal signal in topex / poseidon altimetric data is the largest contributor to sea surface height variability and accounts for more than 80 % of the signal variance . so it is urgent to develop tide model in the shallow area wi th high accuracy 潮汐是高度计资料海面变化中最大的成份,占总变化80以上,伴随着卫星高度计资料在海洋研究中的广泛应用,发展基于卫星高度计资料的高精度浅海潮汐模型成为进一步利用高度计资料研究其它物理海洋问题的基础。
