摘要

Results of numerical modeling to reconstruct the circulation in the region of the Tsushima Strait using the variation method based on a specially developed regional model of the general ocean circulation are presented in this paper.Optimal solutions describing the climatic mean circulation and synoptic circulation in 1999-2000 were obtained on the basis of climatic data and current measurements in the strait carried out in 1999-2000.The variation algorithm for the data assimilation was implemented on the basis of the modification of the general circulation model developed at the Laboratoire d'Oceanographie Dynamique et de Climatologie.Semi-implicit formulation of the finite difference model significantly simplifies the solution of the data assimilation problem.The results of the data assimilation during a 9-month-long period allow us to make conclusions about the applicability and efficiency of the developed variation algorithm for the data assimilation to reproduce the seasonal cycle in limited regions of the World Ocean with open boundaries.
