| 摘 要： | 基于余水位的配置模型,通过潮汐调和分析,利用已知长期验潮站余水位结合临近短期验潮站天文潮位来恢复短期站的实际水位,并对其进行误差分析,证明基于余水位进行推算未知验潮站潮位的可行性与实用性。为了保证验潮仪采集数据的精确度,基于日(月)平均海面在较大的空间尺度内有较强的相关性这一原理,对短期验潮站验潮仪零点漂移进行检测,并对其进行误差分析。

| Abstract: | Based on model of residual water level, this study recovered water level of short-term stations in combination of known long-term tide gauge stations and astronomical tide in short-term tide gauge stations by tidal harmonic analysis. The uncertainty of the performance was also considered during the analysis. The results proved possibility to predict the water level of unknown tide gauges by figuring residual water level. In view of a significant correlation existed between daily and monthly averages of sea level in a large spatial scale, tide gauge instrument at zero drift was tested to ensure accuracy of data collection under consideration of its uncertainties. |
