标题： An oceanic basin oscillation-driving mechanism for tides

摘要： 潮汐代表海岸线和海洋中每天的高潮和低潮交替，当前理论（称为引力强迫机制）将其解释为海水对月球（太阳）引力作用的响应表现。 然而，尽管代表当前理论的纯流体力学模型已在全球海洋中广泛测试，但它们的潮位精度通常较低。 这表明对于引力强迫机制是否是潮汐的最佳解释存在不确定性。 在本研究中，我们提出了一种新理论（称为海洋盆地振荡驱动机制），其中潮汐被解释为与由于月球（太阳）引起的伸长旋转固态地球紧密相关的振荡海洋盆地的表现。 基于这一新理论，我们开发了一个代数潮汐模型，并利用太平洋海洋33个底部压力站11年的观测数据对其进行测试，该模型预测的潮位与观测值的平均均方根（RMS）偏差为7.54厘米。 使用M2潮位RMS与海洋潮汐模型EOT11a的总潮位RMS的比值作为参考，我们估计六个纯流体力学模型（即Hallberg等密度面模型、OSU潮汐反演软件-GN、STORMTIDE模型、OSU潮汐反演软件-ERB、STM-1B和HYbrid坐标海洋模型）的总潮位RMS分别为59.93、51.64、57.05、38.56、86.92和53.56厘米。 显示英文摘要

摘要： Tides represent the daily alternations of high and low waters along coastlines and in oceans, and the current theory (termed the gravitational forcing mechanism) explains them as a manifestation of the response of ocean water to the Moon's (Sun's) gravitational force. However, although the purely hydrodynamic models representing the current theory have been widely tested over global ocean,their tidal elevation accuracies are generally low. This implies an uncertainty as to whether the gravitational forcing mechanism is the best explanation for tides. In this study, we present a new theory (termed the oceanic basin oscillation-driving mechanism), in which tides are explained as a manifestation of oscillating ocean basin that is intricately linked to the elongated spinning solid Earth due to the Moon (Sun). Based on this new theory, we develop an algebraic tide model and test it using 11-year observations from 33 bottom pressure stations over the Pacific Ocean, the average Root Mean Square (RMS) deviation of tidal elevation predicted by this model against observation is 7.54 cm. Using a ratio of M2 elevation RMS of ocean tide model EOT11a and its total tidal elevation RMS as a reference, we estimate the total tidal elevation RMS of six purely hydrodynamic models (i.e.,Hallberg Isopycnal Model, OSU Tidal Inversion software-GN ,STORMTIDE model, OSU Tidal Inversion Software-ERB,STM-1B, and HYbrid Coordinate Ocean Model to be 59.93, 51.64, 57.05, 38.56, 86.92, and 53.56 cm, respectively.
