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.

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.

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. ...

Available in PDF, EPUB and Kindle. Book excerpt: The ocean has entranced mankind for as long as we have gazed upon it, traversed it, dived into it, and studied it. It remains ever changing and seemingly never changing. Each wave that progresses through the. imme diate surf zone on every coast is strikingly different, yet the waves come again and again, as if never to end. The seasons come with essential reg ularity, and· yet each is individual-whatever did happen to that year of the normal rainfall or tidal behavior? This fascination with the currents of the ocean has always had a most immediate practical aspect: shipping, transportation, commerce, and war have depended upon our knowledge, when we had it, and floundered on our surprising ignorance more often than we wish to reflect. These important practical issues have commanded attention from commercial, academic, and military research scientists and engineers from the earliest era of organized scientific investigation. The matter of direct and insistent investigation was from the outset the behavior of ocean currents with long time scales; namely, those varying on annual or at least seasonal cycles. Planning for all the named enterprises depended, as they still do, of course, on the ability to predict with some certainty this class of phenomena. That ability, as with most physical sci ence, is predicated on a firm basis of observational fact to establish what, amorig the myriad of mathematical possibilities, is chosen by Nature as her expression of fact.

Available in PDF, EPUB and Kindle. Book excerpt: An overview of the advances made in the last decade and a half in this field. Based on an advanced graduate level course, the book represents fundamental insights into the structure of the physical theory of the large-scale dynamics of the oceans. The author has maintained throughout a blend of analytical and numerical results so as to achieve as deep a physical understanding of the dynamics of the large-scale circulations as possible. The results of the theories are compared with observations and the success or inadequacies of the theories are highlighted. Topics of particular interest are: theory of the wind-driven circulation, the thermocline, the equatorial circulation and the abyssal circulation. Much of the material - previously scattered throughout the literature - has been collated here for the first time.

Download or read book Hybrid Computer Simulation of Wind-driven Ocean Currents written by Francis Joseph Vithayathil and published by . This book was released on 1974 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simulation method using a hybrid computer is developed in this dissertation to enhance the study of wind-driven ocean circulation. The simulation is based on the mathematical model developed by Ekman. Pure digital simulation is not economical due to excessive computer time required for the solution of the partial differential equations in the model. The ability of the analog section in the hybrid computer to solve differential equations rapidly and the data handling capability and programming simplicity of the digital section are utilized in the hybrid simulation. The results of the computer simulation for the simplified case of a step-function change in wind show good agreement with the results obtained by other investigators. Time-series wind data measured from a fixed buoy were used to calculate the wind stress, which formed the input to the computer model. Ocean current data taken concurrently with the wind data were used for comparison with the simulation results. Spectral analysis of the current meter record revealed the presence of diurnal and semidiurnal tidal components along with the wind driven currents. For comparison purposes, the major tidal influence from one of the current data series was filtered out by digital methods. Using only an average value for the eddy viscosity coefficient, it was found possible to reproduce some of the features of the measured currents in the computer model. For example, both the measured and simulated currents showed inertial oscillations. A simple parameter optimization scheme to determine the value of eddy viscosity coefficient was performed to demonstrate the power of the hybrid simulation in the estimation of unknown parameters in the mathematical model for the wind-driven currents.
