摘要
从分潮数目选择、调和常数稳定性优化两个关键环节入手,选择11个主要分潮用于潮位推算,并利用邻近长期站对中短期验潮站调和常数做差比订正,显著提高了中短期验潮站的潮位推算精度。
This paper starts from two key aspects,namely selecting number of tidal components and optimizing the stability for harmonic constant.There are 11 tidal projections chosen to estimate sea levels.Furthermore,correction for the differences in harmonic constants between long-term tide gauge and the nearby short-term one is involved,which significantly improves the accuracy of forecasting for short-term tide gauge.
