The Accuracy Evaluation of Harmonic Constants for Long Term Tidal Stations Along the Coast of China
摘要
Abstract
The accuracy index and the approaches of accuracy evaluations for tidal harmonic constants at tidal stations are discussed. For the typical long term tidal stations along the coast of China, the accuracy evaluations are performed based on statistics of the analyzed results series from yearly and monthly observations. The statistics shows that the harmonic constants at stations face to open ocean and seas can reach mm and cm accuracy level for yearly and monthly results respectively. However, for the tidal stations along the other part of the coast of China,the harmonic constants represent tendency or periodic variation with large magnitude. For the applications of tides to calculate chart datum and for the evaluation of tide models, it is essential to define reference epoch and to correct the harmonic constants.关键词
