论文摘要

几十年来,已经讨论了全球变暖,并且是不同研究领域中最受欢迎的主题之一。近几十年来,海平面的上升主要是由全球变暖引起的,它引起了科学家的极大关注和兴趣,因为它对人类的生命以及整个地球系统至关重要。具有潜在能源景观的广义施罗宾格桥问题用于对此过程进行建模。我们引入了一种与给定初始分布(1994年的海平面高度)和给定的结尾分布(2014年的海平面高度)的相关混合控制问题的迭代数值方法。引入的迭代方法用于查找SSH的最佳转换路径的收敛是数值验证的。从1994年8月到2014年8月,在模型模拟过程中表征了海平面高度的演变,并且在海洋中尺度涡流引起的几个重要领域的海平面进化被陶醉了。

Global warming has been discussed for decades and is one of most popular topics in different areas of research. The sea level rise in recent decades, which was mainly caused by global warming, has drawn great attentions and interests from scientists because it is crucial to human life as well as the entire earth system. A generalized Schrodinger bridge problem with an underlying energy landscape is used to model this process. We introduce an iterative numerical method for the associated mixed control problem with a given initial distribution (sea level height at the year 1994) and a given ending distribution (sea level height at the year 2014). The convergence of the introduced iterative method for finding the optimal transformation path of SSH is validated numerically. The evolution of sea level height from August 1994 to August 2014 has been characterized during the model simulation and the sea level height evolutions in several significant areas induced by ocean mesoscale eddies are reveled.
