Book excerpt: Nous étudions le rôle des processus océaniques à petite échelle dans la formation et transformation des eaux de surface et intermédiaires qui participent à l'échange Indo- Atlantique à travers le Bassin du Cap. La dynamique de cette région est caractérisée par une forte turbulence et nous montrons l'impact que les structures de méso- ou de sous-méso- échelle, leurs interactions dynamiques et leur variabilité saisonnière ont sur les eaux locales de la thermocline. Une série des simulations numériques, allant de 'eddypermitting' à 'submesoscale resolving', souligne l'importance d'une résolution verticale adéquate pour bien représenter les propriétés des masses d'eau.Les tourbillons de Aiguilles sont principalement générés par des instabilités baroclines, et sont caractérisés par une saisonnalité, liée aux différentes instabilités dans les couches supérieures. En été, les instabilités symétriques sont plutôt en jeu, tandis qu'en hiver les instabilités de la couche de mélange prédominent.L'instabilité barocline de Charney connecte ces deux régimes de la sous-méso-échelle et joue un rôle majeur dans la formation saisonnière d'un nouveau type d'eaux modales : l'Agulhas Rings Mode Water.Enfin, on montre que tant les cyclones que les anticyclones transportent et mélangent l'Antarctic IntermediateWater, l'étirement de la méso-échelle produisant des filaments et structures thermohalines très fines.Nos résultats suggèrent l'existence des deux régimes dynamiques qui affectent les couches supérieures et intermédiaires du Bassin du Cap. Près de la surface, la frontogenèse et une énergique sous-méso-échelle conduisent à un régime agéostrophique. Les profondeurs intermédiaires sont caractérisées par un régime quasi-géostrophique due à l'action prédominante de la méso-échelle.

Book Synopsis Natural Climate Variability on Decade-to-Century Time Scales by : National Research Council
Download or read book Natural Climate Variability on Decade-to-Century Time Scales written by National Research Council and published by National Academies Press. This book was released on 1996-08-30 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reflects the current state of scientific knowledge about natural climate variability on decade-to-century time scales. It covers a wide range of relevant subjects, including the characteristics of the atmosphere and ocean environments as well as the methods used to describe and analyze them, such as proxy data and numerical models. They clearly demonstrate the range, persistence, and magnitude of climate variability as represented by many different indicators. Not only do natural climate variations have important socioeconomic effects, but they must be better understood before possible anthropogenic effects (from greenhouse gas emissions, for instance) can be evaluated. A topical essay introduces each of the disciplines represented, providing the nonscientist with a perspective on the field and linking the papers to the larger issues in climate research. In its conclusions section, the book evaluates progress in the different areas and makes recommendations for the direction and conduct of future climate research. This book, while consisting of technical papers, is also accessible to the interested layperson.

Available in PDF, EPUB and Kindle. Book excerpt: For advanced undergraduate and beginning graduate students in atmospheric, oceanic, and climate science, Atmosphere, Ocean and Climate Dynamics is an introductory textbook on the circulations of the atmosphere and ocean and their interaction, with an emphasis on global scales. It will give students a good grasp of what the atmosphere and oceans look like on the large-scale and why they look that way. The role of the oceans in climate and paleoclimate is also discussed. The combination of observations, theory and accompanying illustrative laboratory experiments sets this text apart by making it accessible to students with no prior training in meteorology or oceanography. * Written at a mathematical level that is appealing for undergraduates and beginning graduate students * Provides a useful educational tool through a combination of observations and laboratory demonstrations which can be viewed over the web * Contains instructions on how to reproduce the simple but informative laboratory experiments * Includes copious problems (with sample answers) to help students learn the material.

Book Synopsis Ocean Circulation and Climate by : Shiro Imawaki
Download or read book Ocean Circulation and Climate written by Shiro Imawaki and published by Elsevier Inc. Chapters. This book was released on 2013-10-22 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strong, persistent currents along the western boundaries of the world’s major ocean basins are called “western boundary currents” (WBCs). This chapter describes the structure and dynamics of WBCs, their roles in basin-scale circulation, regional variability, and their influence on atmosphere and climate. WBCs are largely a manifestation of wind-driven circulation; they compensate the meridional Sverdrup transport induced by the winds over the ocean interior. Some WBCs also play a role in the global thermohaline circulation, through inter-gyre and inter-basin water exchanges. After separation from the boundary, most WBCs have zonal extensions, which exhibit high eddy kinetic energy due to flow instabilities, and large surface fluxes of heat and carbon dioxide. The WBCs described here in detail are the Gulf Stream, Brazil and Malvinas Currents in the Atlantic, the Somali and Agulhas Currents in the Indian, and the Kuroshio and East Australian Current in the Pacific Ocean.

Book Synopsis Kuroshio Current by : Takeyoshi Nagai
Download or read book Kuroshio Current written by Takeyoshi Nagai and published by John Wiley & Sons. This book was released on 2019-05-29 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: An interdisciplinary study of the Kuroshio nutrient stream The surface water of the Kuroshio, a western boundary current in the North Pacific Ocean, is nutrient-depleted and has relatively low primary productivity, yet abundant fish populations are supported in the region. This is called the “Kuroshio Paradox”. Kuroshio Current: Physical, Biogeochemical and Ecosystem Dynamics presents research from a multidisciplinary team that conducted observational and modeling studies to investigate this contradiction. This timely and important contribution to the ocean sciences literature provides a comprehensive analysis of the Kuroshio. Volume highlights include: New insights into the role of the Kuroshio as a nutrient stream The first interdisciplinary examination of the Kuroshio Paradox Reflections on the influence of the Kuroshio on Japanese culture Research results on both the lower and higher trophic levels in the Kuroshio ecosystem Comparisons of nutrient dynamics in the Kuroshio and Gulf Stream Predictions of ecosystem responses to future climate variability
Book Synopsis Buoyancy Effects on Coastal and Estuarine Dynamics by : D. G. Aubrey
Download or read book Buoyancy Effects on Coastal and Estuarine Dynamics written by D. G. Aubrey and published by American Geophysical Union. This book was released on 1996-01-09 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 53. Coastal water quality, flooding, estuarine habitat diversity, and distribution of coastal organisms depend in part on the dynamics of the coastal water column. Particularly within coastal embayments and estuaries, areas within the influence of freshwater from surface and ground water sources, the water column may be stratified by temperature and/or salinity. Resulting density gradients affect the behavior of the water column, including mixing and transport processes. Understanding physical processes associated with buoyancy in the coastal oceans is a requisite first step towards understanding the effects of buoyancy on coastal processes, including geological, biological and geochemical aspects. This volume presents 23 papers addressing various aspects of buoyancy in the coastal oceans, including plumes, tidal interaction with buoyancy, shelf dynamics and mixing processes, and estuarine dynamics of buoyancy. The interwoven common thread amongst these articles is how buoyancy processes affect the density stratification and dynamics of shallow coastal flows.
