摘要
介绍了利用最小二乘法计算潮汐调和常数的方法,采用中国沿海具有代表性的长期验潮站数据进行了调和分析,并与NA099b海潮模型进行对比。结果表明,采用1年资料生成的调和常数已趋于稳定,NA099b海潮模型在我国海域的振幅精度为±O.15m。
The method to calculate tidal harmonic constants using the least squares is introduced. Harmonic analysis is conducted with long term data collected from typical tidal stations along the coast of China, and the obtained constants are compared with NAO99b tidal model. The results show that the harmonic constants calculated from oneyear long observations are tending towards stability, and the precision of NAO99b tidal model in the sea area of China amounts to ± 0.15m.
