摘要
发现了由一个月逐时潮位观测资料调和分析求得的调和常数与年资料观测序列分析结果存在的明显偏差,而且这种偏差在同步观测的邻近验潮站之间具有一定的相关性。设计并实现了由长期验潮站观测资料或分析结果订正月观测资料调和常数的三种算法,实例验证了订正效果。
It is discovered that large bias exists in harmonic constants of tides derived from monthly tidal observations,and that the biases show correlation between adjacent tidal gauge stations.Three algorithms are designed for the correction of harmonic constants from monthly observation through the information from the adjacent long term tidal gauge station.Example is given for verifying the efficiency of the algorithms presented in this paper.
