Considered in a two-layer prognostic model of the circulation in the Gulf of Mexico. This two-layer model represents the simplest finite difference approximation to the continuously stratified real ocean. The equations of momentum, which are considered for each layer, include horizontal and vertical exchange of momentum, Coriolis effect, non-linear advection of momentum and the effect of topography. In the model, however, the topography is restricted to the lower layer. The associated vorticity equations are formed and the baroclinic and barotropic modes are separated. The baroclinic and barotropic vorticity prediction equations are then put into finite difference form utilizing centered differences with a double step in time. The Du Fort-Frankel scheme is used for the lateral diffusion of vorticity terms and the resulting system of finite difference equations are solved using the Gauss-Seidel method with successive over-relaxation. Laplacian flow is initially specified in the upper layer and the lower layer is considered at rest. The model is spun up to a quasi-steady state which is in turn used as the initial state for the subsequent computations. A one-year prediction is then made of the baroclinic and barotropic modes of circulation in the Gulf of Mexico during which time the input through the Yucatan Strait is varied seasonally. (Author).

For the past several years, a number of research programs have funded significant efforts to advance understanding of and forecasting capabilities for the Gulf of Mexico circulation, including the Loop Current, its associated eddies, and abyssal dynamics. One such program is the National Academies’ Understanding Gulf Ocean Systems initiative, which focuses on improving forecasts of the physical dynamics of the open Gulf of Mexico in space and time scales useful for the reduction of risks to offshore energy exploration and production, as well as for other challenges such as forecasting hurricane intensification and managing fisheries. What has been learned, how can this scientific progress be incorporated into operational models, and what are the remaining gaps in knowledge impeding predictive skill?

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 161. In this book, we describe our current state of knowledge on circulation in the Gulf of Mexico through 22 papers at the forefront of research. The view is selective rather than all-inclusive, with primary focus on circulation at the sea surface and at depth, including nearshore flow. In choosing topics, we have attempted to avoid the distinction between observations and models, as both are essential to advance our understanding of this exceptional body of water. We have also written for specialists and non-specialists alike in both science and industry: for those who work directly on the science associated with the Gulf, and for those whose work depends on the Gulf. And we refer here to physical oceanography, marine geology, sedimentology, coastal and estuarine science, as well as to the petrochemical and fishing industries.

"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. The extensive list of references make this book a valuable text for both graduate students and postdoctoral researchers in the marine sciences and in related fields, such as meteorology, climate and coupled biogeochemical modeling."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

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.
