全球垂向位移负荷潮模式在渤海、黄海、东海及周边区域的准确度评估

Accuracy assessment of global vertical displacement loading tide models in the Bohai Sea,Yellow Sea,East China Sea and surrounding areas

本研究利用渤海、黄海、东海及周边区域21个GPS站的调和常数资料,对5个全球垂向位移负荷潮模式(FES2014、EOT11a、GOT4.10c、GOT4.8和NAO.99b)在渤海、黄海、东海及周边区域的准确度进行了评估。结果表明,在渤海、黄海、东海及周边区域,对于M_(2)分潮,FES2014和EOT11a模式结果准确度相对较高;对于S_(2)分潮,NAO.99b和EOT11a模式结果准确度相对较高;对于K_(1)分潮,EOT11a和FES2014模式结果准确度相对较高;对于O_(1)分潮,EOT11a和GOT4.8模式结果准确度相对较高;对于N_(2)分潮,EOT11a和FES2014模式结果准确度相对较高;对于K_(2)分潮,NAO.99b和FES2014模式结果准确度相对较高;对于P_(1)分潮,EOT11a和GOT4.8模式结果准确度相对较高;对于Q_(1)分潮,FES2014和EOT11a模式结果准确度相对较高。除此之外,本文还简单分析了渤海、黄海、东海及周边区域8个主要分潮的垂向位移负荷潮分布特征。

In this study,the harmonic constants of the 5 global vertical displacement loading tide models FES2014,EOT11a,GOT4.10c,GOT4.8 and NAO.99b are validated evaluated to the observed data of 21 GPS stations in Bohai Sea,Yellow Sea,East China Sea and surrounding areas.The results show that the accuracy of the M_(2) constituents of FES2014 and EOT11a models are relatively high,S_(2) constituents of NAO.99b and EOT11a models are relatively high,K_(1) constituents of EOT11a and FES2014 models are relatively high,O_(1) constituents of EOT11a and GOT4.8 models are relatively high,N_(2) constituents of EOT11a and FES2014 models are relatively high,K_(2) constituents of NAO.99b and FES2014 models are relatively high,P_(1) constituents of EOT11a and GOT4.8 models are relatively high,Q_(1) constituents of FES2014 and EOT11a models are relatively high.The distribution features of the eight vertical displacement loading tides in Bohai Sea,Yellow Sea,East China Sea and surrounding areas.
