一个东海潮汐数值模式及检验
Verification of a tidal model for the East China Sea
摘要
Abstract
In this paper,measured data from the Donghai Daqiao and Yangshan Stations are used to verify the accuracy of a tidal model.First,the process for performing a tide harmonic analysis of these stations is verified using the T_TIDE package.Second,the eight major subtides in the study area,including M2,S2,K1,O1,N2,K2,P1,and Q1,are compared to the harmonic analysis results of the measured data and model results of the two stations.The ratio of the mean square error D of the model results and sea surface height observation of the two stations to the tidal sea surface height change V is found to be 25.99％and 25.29％,respectively.Finally,the cotidal maps for the M2 and K1 subtides calculated using the model results are compared with those reported by Fang(1986).Furthermore,the cotidal maps drawn utilizing the model are characteristically similar to those reported in previous studies,and uncertain factors possibly leading to the low accuracy of the developed numerical model are analyzed.The accuracy of the East China Sea tidal model needs to be improved for amplitude simulation.This improvement would benefit further understanding of tidal currents in the East China Sea.关键词
