摘要为了更好地了解沿海海平面的变化和变化，提出了一种利用海洋内部海平面信息预测沿弯曲西边界沿着海平面的理论。西边界海平面在一个特定的纬度表示的贡献的总和从内部海平面传播到西边界的长Rossby波之间的纬度和较高的纬度，从西边界海平面。这个理论是通过使用线性，减少重力模型。理论和模型之间的比较显示出良好的一致性。一个简单的比例定律（或经验法则）从理论中得出的高纬度海平面和海洋内部海平面的贡献提供了一个衡量。然后，使用耦合模式相互比较项目（CMIP 5）第5阶段的34个气候模式的数据，对20世纪末至21世纪之间的海平面动态变化进行了测试。该理论抓住了nea…
AbstractTo better understand coastal sea level variability and changes, a theory that predicts sea levels along a curved western boundary using interior ocean sea level information is proposed. The western boundary sea level at a particular latitude is expressed by the sum of contributions from interior sea levels propagating onto the western boundary by long Rossby waves between that latitude and a higher latitude, and from the western boundary sea level at the higher latitude. This theory is examined by using a linear, reduced gravity model. A comparison between the theory and the model shows good agreement. A simple scaling law (or rule of thumb) derived from the theory provides a measure of the higher-latitude sea level and ocean interior sea level contributions. The theory is then tested using data from 34 climate models in phase 5 of the Coupled Model Intercomparison Project (CMIP5) for dynamic sea level changes between the end of the twentieth and twenty-first centuries. The theory captures the nea...
