摘要
采用全球分布的565个验潮站水位资料对NAO.99b,CSR4.0和TPXO7.2三种潮汐模型进行精度评估。结果表明:在全球海洋范围内,NAO.99b模型精度最高;在黄海海域,TPXO7.2模型的精度最高;在东海和南海海域,则是NAO.99b模型最优;在深海海域,三种模型精度差异不大;在浅海海域,采用同化方法的潮汐模型比采用经验方法的潮汐模型更有优势。
565 tidal gauge stations are used to analysis the accuracy of NAO. 99b ,CSR4.0 and TPXO7.2 tide models. The results show that the performance of NAO. 99b is globally best. Among these models ,TPXO7.2 has the best accuracy in the Yellow Sea, and in the East China Sea and South China Sea, NAO. 99b fits the tide gauge data better. The difference of three models＇ accuracy is little in deep ocean areas, but the model using assimilation methods has more advantage than that using empirical methods in shallow waters.
