Abstract

An algorithm for taking into account salt fluxes through the open boundary of the simulated water area, that is based on the method of variational data assimilation, is proposed. The results of the numerical experiment on simulating the major Baltic inflow that occurred in December 2014 are presented. The experiment utilized the Baltic Sea hydrodynamic model developed on the basis of the INMOM ocean and sea circulation model with implementation of the proposed algorithm. A comparison between the simulation results obtained using the algorithm and the results obtained by relaxation to observational data is carried out.

基于盐度数据变分同化的波罗的海水热力学模型中开放横向边界条件的设定方法

摘要

提出了一种基于变分数据同化方法的模拟水域开放边界盐通量计算算法。给出了模拟 2014 年 12 月发生的波罗的海主要流入的数值实验结果。实验利用了在INMOM海洋和海洋环流模型基础上开发的波罗的海水动力模型，并实施了所提算法。将使用该算法获得的模拟结果与通过对观测数据进行松弛获得的结果进行了比较。
