| 摘 要： | 平均大潮高潮面在我国用作海洋测绘净空信息表示的参考面。论证了该特征潮面的定义,扩充了其含义范围,将回归潮高高潮位应用为平均大潮高潮位。分析描述了实测潮位和预报潮位统计计算方法,比较了统计方法与潮汐特征值算法的符合度,计算了平均大潮高潮位与理论最高潮位的比率。基本研究结论是:对规则半日潮和规则日潮海域,统计算法和特征值算法的结果较为一致,而混合潮海域,两种特征潮位之间存在明显差异,平均大潮高潮位计算的相关问题需深入系统论证。

| Abstract: | Mean high water spring （ MHWS ） is applied as reference surface for the expression of clearance height information in hydrography. In this paper, the definition of this characteristic water level is demonstrated, and it is extended to all types of tides. The tropical higher high water （THHW） is quoted as the M/-IWS for the diurnal and mixed tides. The statistical algorithms from the observed and predicted tidal data are described and analyzed. The coincidence of results from both from the statistics and characteristic value algorithm is verified. The ratio between MHWS and the normal highest high water is calculated for the long term tidal stations along the coast of China. The fundamental conclusion drawn from this paper is that a satisfy accordance between the results both from the statistics and characteristic value algorithm for semidiurnal and diurnal tidal area, and for the mixed tidal area, large differences exist between MHWS and THHW. In this type of tidal area, detail researches will be made for the calculation of MHWS. |
