The relationship between barotropic tidal currents and sea level were established for the first 45-day period using the transfer functions and harmonic analysis, and then carry the prediction for the second 45-day period. There is very good agreement between the observed and predicted semidiurnal tidal current, the rms error is less than 3 cm s-1. However, prediction on diurnal tidal current is rather disappointing, the rms error is about 19 cm s-1, suggesting strong baroclinic tidal component may have a significant contribution to the tidal current, which is not registered in the sea level records.
利用转换函数与调和分析两种方法,验证水位预报正压潮流的可行性,将观测资料分为等长的两段时期,藉由第一段时期约45天的正压潮流与水位的关系,预报下一段时期约45天的正压潮流,结果显示半日潮流的观测值与预报值大致符合,其均方根约在3公分/秒以下;但是全日潮流的观测值与预报值的差异大,其均方根最大可达到约19公分/秒,推测其原因为斜压潮分量大而影响潮流,但是不会对水位资料造成影响。
