Analysis of the barotropic model of the subtropical gyre in the ocean for finite Reynolds numbers. Part II.
Abstract:This paper is a continuation of Part I of the suggested study of the barotropic model of the subtropical gyre for finite Reynolds numbers. The statement of the problem, the motivation of the analysis, and the description of the general properties of the solution are presented in Part I (Kamenkovich et al., 1995). Here, in Part II of the study, the detailed investigations of the peculiarities of the solution are offered. The most striking feature of the solution is the formation of a recirculation gyre in the northwest corner of the basin. To study the gyre structure for various Reynolds numbers the time-averaged fields of the stream function, and that of the relative and potential vorticity are thoroughly examined. The role of the eddies, appeared within the boundary layer, in the transfer of positive vorticity from the west coast is clarified. The analysis of the energy characteristics of the system is presented and the vorticity balance both integral and regional (within a closed streamline) is elucidated. Finally, the consistent discussion of the process of the formation of the recirculation gyre for different Reynolds numbers is suggested.

- The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
