| 摘要: |
| 根据Munk 等提出的响应法( Response Method) 和Groves 等( 1975) 的正交响应方法( Orthogonalized Convolution Method) 的思想, 利用正交潮响应法对248 个周期超过6 年的南中国海的TOPEX/ POSEIDON 卫星高度计资料进行潮波分析。在分析中引入全日潮族和半日潮族,并利用正交潮函数( Orthotide Function) 分析出了3 个主要的全日分潮( K1、O1、P1) 和3 个主要半日分潮(M2、S2、N2) , 并给出了K1、O1、M2、S2 的等振幅线和同潮时图, 结果与其他学者的主要结果符合得很好。通过与整个海区53 个验潮站的主要全日分潮K1 分潮和主要半日分潮M2 分潮的比较, K1 分潮的振幅和迟角的平均绝对误差分别为4.73cm 和11.6?, 而M2 分潮的分别为11.91cm 和28.4?, 优于Mazzega( 1994) 的结果。 |

| Abstract: |
| Based upon the response method presented by Munk et al ( 1966) , and the orthogonalized convolution method given by Groves et al ( 1975) , a procedure is used to analyze TOPEX/POSEIDON satellite altimeter data in the South China Sea, which was produced by the Jet Propulsion Laboratory Distributed Active Archive Center. Six principal tidal constituents K1, O1, P1, M2, S2 and N2 are inversed by the orthogonized tidal function, and the tidal regimes are presented. The results agree well with the results obtained elsewhere. Compared with the results from the data of 53 tide gauge stations, the average absolute error for the K1 constituent between the computed and the observed harmonic constants are 4.73cm and 11.6? for amplitudes and phase-lags respectively, these are 11.91cm and 28.43? for M2 constituent. Such results are more accurate than those derived Mazzega( 1994) ( 15—20cm for M2) . |
