摘要

本文研究并提出了一种基于海洋潮汐动力模型的水位改正方法。该方法通过对数值模拟的天文潮位进行改正,结合残差改正获得特定站的潮位数据。结合实际资料,将基于海洋潮汐动力模型的水位改正方法与传统的水位改正方法(时差法和最小二乘潮位拟合法)进行了比较,新方法改正的精度明显高于传统方法,显示其在地形变化较为复杂海域进行水位改正的可行性与独特优势。该方法可以在海洋测绘中减少短期验潮站的布设,用于潮位序列缺失的修补。

Abstract

A water-level correction method based on ocean tide dynamic model was studied and proposed. This method corrected astronomical tide projected by numerical simulation, combined with the correction of residual water level, and obtained the tide data of specific station. Combined with the actual data, this method compared with the traditional level correction method (the time- difference method and least squares fitting method). The results show that it has higher accuracy than that of traditional methods, and has unique advantages in more complex topography seas. This method can reduce the short-term tide gauge emplaced in the hydrographic surveying and charting,and use for fixing the missing tide level.
