采用Green函数方法,高分辨率中国近海区域海潮模型和TOPO7.0全球海洋潮汐模型,以及Gutenberg-BullenA地球模型计算了负荷潮.结果表明,渤、黄、东海M2垂向位移负荷潮振幅最大值出现在浙江外海约150km处,其值超过28mm;次大值位于仁川湾,超过20mm;第三大值位于北黄海东北部,超过14mm.S2垂向位移负荷潮在上述三处的振幅值分别超过10,8和4mm.K1和O1垂向位移负荷潮振幅在琉球群岛中北部附近为最大,分别超过13和10mm:向内海逐渐减小.半日分潮垂向位移负荷潮基本上与海洋潮汐对应分潮具有相反的位相.在东海大部和南黄海东部全日分潮垂向位移负荷潮与对应的海潮分潮基本上具有反位相的关系,而在渤、黄海其余海域基本上不具有反位相关系.在研究海区内,全日潮的垂向位移负荷潮不出现无潮点.自吸-负荷平衡潮分布特征与垂向位移负荷潮相近,其振幅大约是垂向位移负荷潮的1.2~1.7倍,其位相与垂向位移负荷潮基本上相反.M2最大振幅值也出现在浙江外海,超过42mm.
The maximum tidal load amplitude of M2 in the Bohai Sea, the Yellow Sea and the East China Sea was calculated using the Green function method, the tide model of the high resolution China offshore region, the TOPO7.0 global ocean tide model, and the Gutenberg-BullenA earth model Appeared in the Zhejiang offshore at about 150km, its value exceeds 28mm; the second largest value is located in Incheon Bay, more than 20mm; the third largest value is located in the northeastern North Yellow Sea, more than 14mm.S2 vertical displacement load tide in the three amplitude Over 10, 8 and 4 mm.K1 and O1 vertical displacement load tidal amplitude is the largest in the central and northern part of the Ryukyu Islands, more than 13 and 10mm respectively: gradually decreases toward the inland sea.The vertical displacement load tide of semi-diurnal tide is basically the same with the ocean tide The corresponding tidal currents have the opposite phase. In the East China Sea and the eastern part of the South Yellow Sea, the vertical tidal displacement load tidal wave of the whole daytime tidal moratorium basically has the anti-phase relationship with the corresponding tidal tide tidal wave, while the other parts of the Bohai Sea and the Yellow Sea sea basically have no anti In the study area, the tidal vertical displacement load tide does not appear the tide-free point.The self-priming-load balance tidal distribution is similar to the vertical displacement load tide, and its amplitude is about the vertical displacement load Tidal 1.2 ~ 1.7 times, its phase and vertical displacement load tide is basically the opposite .M2 maximum amplitude also appears in the offshore Zhejiang, more than 42mm.
