Book On the Barotropic Model of the Ocean Circulation

Download or read book On the Barotropic Model of the Ocean Circulation written by V. Barcilon and published by . This book was released on 1987 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper is concerned with the question of whether ocean circulation models have unique steady solutions. We consider this question for the simplest such model, namely that of a homogeneous wind-driven ocean, with bottom friction and no topography. We examine the mathematical properties of the solutions of a barotropic, wind driven ocean with bottom friction on both a beta- and f-plane. Except for small Rossby numbers, the uniqueness of the solutions of the corresponding partial differential equations is dependent on an a priori bound for the gradient of the velocity. For the f-plane, two drivings are considered which give rise to explicit, global unique solutions. For large Rossby numbers, a novel nonlocal, nonlinear boundary value problem, which does depend on the beta-effect, is obtained for the circulation.

Book Numerical Ocean Circulation Modeling

Download or read book Numerical Ocean Circulation Modeling written by Aike Beckmann and published by World Scientific. This book was released on 1999-04-29 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive overview of the models and methods employed in the rapidly advancing field of numerical ocean circulation modeling. For those new to the field, concise reviews of the equations of oceanic motion, sub-grid-scale parameterization, and numerical approximation techniques are presented and four specific numerical models, chosen to span the range of current practice, are described in detail. For more advanced users, a suite of model test problems is developed to illustrate the differences among models, and to serve as a first stage in the quantitative evaluation of future algorithms. The extensive list of references makes this book a valuable text for both graduate students and postdoctoral researchers in the marine sciences and in related fields such as meteorology, and climate and coupled biogeochemical modeling.

Book Oceanic Circulation Models Combining Data and Dynamics

Download or read book Oceanic Circulation Models Combining Data and Dynamics written by D.L.T. Anderson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book which is the outcome of a NATO-Advanced Study Institute on Mod elling the Ocean Circulation and Geochemical Tracer Transport is concerned with using models to infer the ocean circulation. Understanding our climate is one of the major problems of the late twentieth century. The possible climatic changes resulting from the rise in atmospheric carbon dioxide and other trace gases are of primary interest and the ocean pla. ys a ma. jor role in determining the magnitude, temporal evolution and regional distribution of those changes. Because of the poor observational basis the ocean general circulation is not well understood. The World Ocean Circulation Experiment (WOCE) which is now underway is an attempt to improve our knowledge of ocean dynamics and thermodynamics on global scales relevant to climate change. Despite those efforts, the oceanic data base is likely to remain scarce and it is crucial to use appropriate methods in order to extract the maximum amount of information from observations. The book contains a thorough analysis of methods to combine data of val'ious types with dynamical concepts, and to assimilate data directly into ocean models. The properties of geocl;temical tracers such as HC, He, Tritium and Freons and how they may be used to impose integral constraints on the ocean circulation are discussed.

Book Wind Driven Ocean Modeling and Ocean Model Development

Download or read book Wind Driven Ocean Modeling and Ocean Model Development written by Alan J. Wallcraft and published by . This book was released on 1985 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical simulations were performed with a 0.2 deg, two layer, free surface, primitive equation, ocean circulation model of the Gulf of Mexico with a realistic bottom topography and coastline. As in previous simulations, with idealized bottom topography and coastline, realistic Loop Current behavior could be obtained without wind forcing and with constant inflow through the Yucatan Straits. However, simulations with both wind and port forcing showed significantly more variation than those with port forcing alone. A similiar two layer model was set up for a North Atlantic region, from 20N, 82W to 48N, 30W, on a 0.25 by 0.2 deg grid. A 'Black Box' multigrid package was prepared for solving finite difference Helmholtz's equations with staggered grid Neumann boundary conditions in nonrectangular regions. In semi-implicit free surface primitive equation ocean models, it is competitive with other powerful iterative methods but slower than the direct Capacitance Matrix Technique. Several wind stress data sets were prepared for use in ocean models, based on global analysis products from FNOC and NMC, regional analysis products from FNOC, and ship observations. These data sets have been used to drive ocean circulation model of the World Ocean, the Indian Ocean, the North Atlantic, and the Western Mediterranean Sea. Keywords: Loop Current; Helmholtz solver; Multigrid method; Multilinear regression; and Wind stresses.

Book On Steady Wind driven Ocean Currents in a Stratified Model of Two Moving Layers

Download or read book On Steady Wind driven Ocean Currents in a Stratified Model of Two Moving Layers written by Worth D. Nowlin and published by . This book was released on 1965 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Considered are steady, wind-driven currents in a two-layer model ocean, confined within a rectangular basin with a horizontal sea bed. The horizontal velocities are assumed independent of elevation within each layer of this finite difference approximation to the continuously stratified real ocean. Neglecting nonlinear field accelerations, a frictional model for the entire basin is formulated which allows for vertical, but not horizontal, transfer of horizontal momentum due to turbulence. The exchange of horizontal momentum between layers and to the sea bed is provided through the assumption of interlayer and bottom stresses, which are assumed proportional to the vertical contrast of horizontal velocity across the appropriate interface. The constants of proportionality, which are estimated from considerations of the observed circulation, play decisive roles in controlling the circulation patterns within each layer and the internal dissipation of energy from the steady organized flow. The solution, obtained for a purely zonal wind stress which varies latitudinally as a cosine, depicts an anticyclonic circulation within the lower layer which is intensified more to the west than is the anticyclonic gyre within the upper layer. Numerical calculations were performed for a range of physical parameters. ...

Book Numerical Modeling of Ocean Circulation

Download or read book Numerical Modeling of Ocean Circulation written by Robert N. Miller and published by Cambridge University Press. This book was released on 2007-01-18 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The modelling of ocean circulation is important not only for its own sake, but also in terms of the prediction of weather patterns and the effects of climate change. This 2007 book introduces the basic computational techniques necessary for all models of the ocean and atmosphere, and the conditions they must satisfy. It describes the workings of ocean models, the problems that must be solved in their construction, and how to evaluate computational results. Major emphasis is placed on examining ocean models critically, and determining what they do well and what they do poorly. Numerical analysis is introduced as needed, and exercises are included to illustrate major points. Developed from notes for a course taught in physical oceanography at the College of Oceanic and Atmospheric Sciences at Oregon State University, this book is ideal for graduate students of oceanography, geophysics, climatology and atmospheric science, and researchers in oceanography and atmospheric science.

Book Ocean Circulation and Climate

Download or read book Ocean Circulation and Climate written by Sybren S. Drijfhout and published by Elsevier Inc. Chapters. This book was released on 2013-10-22 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conceptual models are a vital tool for understanding the processes that maintain the global ocean circulation, both in nature and in complex numerical ocean models. In this chapter we provide a broad overview of our conceptual understanding of the wind-driven circulation, the thermohaline circulation, and their transient behavior. While our conceptual understanding of the time-mean wind-driven circulation is now fairly mature, basic questions remain regarding the thermohaline circulation, for example, surrounding its overall strength and stability. Similarly, basic questions remain regarding the transient adjustment and internal variability of the ocean circulation.
