M_(3)海洋分潮(三阶潮或一日三次周期潮汐)经常受到忽视,因而对M_(3)分潮进行更精确的分析研究,可以提高潮汐预测、海洋数值模拟、大地测量的准确度.尽管M_(3)分潮在整体潮汐所占比例较小,但由于陆架共振及其他影响,某些沿海地区M_(3)潮可大大增强.本文使用157个验潮站的数据,以及9年时间窗口,对水位变化进行了潮汐谐波分析.本文还分析了太阴M_(3)潮,将这些结果与全球同化的模型数据(TPXO9v5a)进行了比较,重点研究了西太平洋和欧洲陆架地区.与验潮站数据相比,大部分区域TPXO9v5a导出的M_(3)潮振幅和相位滞后表现良好,但在沿海和地形复杂的区域,其结果误差较大.在欧洲陆架海域使用了一个浅水数值模型(MARS),该模型在某些地区优于TPXO的结果.在欧洲陆架海域的五个子区域中,TPXO在三个地点的M_(3)振幅及相位滞后预测的均方根误差(RMSE)更小.而在其他子区域,MARS模拟结果更为准确.本文发现一些地点的M_(3)振幅有着显著长周期变化,这与海平面上升(SLR)导致的共振效应有关,这种共振效应可以调制海洋对天文引潮力的响应.本文使用MARS模型,应用各种海平面上升的预设情境,对M_(3)振幅的长周期变化进行了模拟研究.结果表明随着时间的推移,超过一半验潮站M_(3)振幅长期变化方向(增加或减少)与MARS模型结果一致.
