This book was released on 2016 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large-scale climate system is driven by imbalances of the reservoirs of heat contained in the world oceans. The transport and redistribution of this heat is determined in part by nonlinear mesoscale eddies (radii ~50-200 km), as well as by planetary waves whose widths approach the size of mesoscale eddies away from the equator. In this dissertation, new analysis techniques are developed and implemented to assess oceanic phenomena in two regions: mesoscale eddy-mean flow interaction in the Kuroshio Extension (KE) region, and the effects of coastal Kelvin waves and mesoscale eddies in the Indian Ocean south of Java. In the KE region, a jet-following coordinate reference frame is used to quantify the contributions of eddies to the vorticity budget along the KE jet in a strongly eddying ocean general circulation model simulation, the Parallel Ocean Program (POP). The jet reference frame preserves synoptic gradients of the jet that are not accurately represented in multi-year Eulerian means. This analysis found that eddies tend to accelerate the jet just downstream of crests in the topographically-induced meanders, implying an intensification of frontal gradients in these areas. In the Indian Ocean, a method involving projections of harmonic basis functions onto altimetry-derived sea level anomaly (SLA) is used to estimate Kelvin wave activity along the equatorial-coastal waveguide. The resulting Kelvin wave coefficient presents a more accurate representation of Kelvin wave activity than that from raw SLA. Moreover, values of the Kelvin wave coefficient in April-June are a robust predictor of positive Indian Ocean Dipole (pIOD) event development later in the calendar year. Finally, a temperature budget using a strongly eddying POP simulation isolates the specific contributions of mesoscale processes south of Java. It shows that Kelvin waves and local wind forcing both contribute substantially to anomalous cooling during pIOD years, while mesoscale eddies have a modest warming effect. These results suggest that mesoscale processes in the study regions have an important influence on the ocean's structure and can trigger a climate response; use of the new analysis techniques may help quantify the effects of mesoscale eddies and planetary waves elsewhere in the oceans.

Available in PDF, EPUB and Kindle. Book excerpt: Extending SCOAR to the tropical Atlantic TIWs shows that air-sea coupling damps the eddy kinetic energy of the waves. TIW-induced wind stress is negatively correlated with the TIW-induced ocean surface current, and this slows down the TIW-currents.
Book Synopsis Coupled Atmosphere-Ocean Dynamics by : Shang-Ping Xie
Download or read book Coupled Atmosphere-Ocean Dynamics written by Shang-Ping Xie and published by Elsevier. This book was released on 2022-12-21 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coupled Atmosphere-Ocean Dynamics of Climate Variability and Climate Change presents the patterns, mechanisms, and predictability of climate variability and anthropogenic climate change. Based on a graduate course the author has taught over 25 years, this book provides the physical foundation for those who are interested in fundamental questions such as: why climate varies from one year to another; how predictable climate is; and how climate will change in the face of increasing greenhouse gases in the atmosphere. This is the first comprehensive and systematic treatment of this subject that simultaneously draws on the latest research and is accessible for graduate students. The book takes a step-by-step systematic approach to coupled ocean-atmosphere interactions. This allows a wide range of comparative views: climate modes among and across different tropical ocean basins, ocean feedback on the atmosphere (in and out of the tropics), and spontaneous internal oscillation versus externally forced climate change. Such comparative views offer unprecedented insight into the dynamics of climate variability and predictability. This book can be used as supplementary reading for advanced undergraduate students, as coursework in climate dynamics, modeling, variability, and change, and as a reference book and research monograph for researchers in ocean, atmospheric, climate, and earth system sciences. Delivers the first authored textbook on ocean-atmosphere interactions that give rise to climate variability/predictability and shape regional patterns of anthropogenic climate change Contains historical accounts of major breakthroughs in the field Includes homework questions, helping to reinforce key concepts and applications

Book Synopsis Ocean Circulation and Climate by : Lee-Lueng Fu
Download or read book Ocean Circulation and Climate written by Lee-Lueng Fu and published by Elsevier Inc. Chapters. This book was released on 2013-10-22 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has seen tremendous progress in the application of ocean remote sensing to the study of the global ocean circulation. This chapter provides a summary of the resultant advances in our understanding of the key processes of the ocean that affect climate variability. Many of the advances result from the combined usage of remote sensing from multiple types of measurement and in situ observations. Remotely sensed ocean variables include sea surface height, wind, temperature, salinity and color, as well as the variable mass of the ocean and ice from spaceborne measurement of the earth’s gravity field. These observations have often been analyzed with various in situ observations, including moored buoys, hydrographic profiles, surface drifters, and Argo floats. The general circulation of the ocean as manifested by the ocean surface dynamic topography from satellite altimetry, and the geoid from satellite gravity measurements, can now be determined at scales approaching 100km. The information from surface drifters and Argo floats has added more details through the upper ocean depths. The large-scale changes of the ocean on decadal scales reveal complex geographic patterns in relation to the changes in the atmospheric forcing. The causes for the slow rise of the global mean sea level are diagnosed in terms of the steric and mass change of the ocean. The bottom pressure inferred from ocean mass change measured from space provides direct observation of the barotropic variability of the ocean. The detailed information of ocean surface wind measured from scatterometry and temperature from infrared and microwave radiometry reveals a positive correlation between the two, leading to new understanding of air–sea interactions at scales below 1000km. Data combined from multiple satellite altimeters through optimally designed processing have revolutionized the study of the global ocean mesoscale processes, revealing new information on the spectral transfer of energy and on global eddy propagation characteristics, which vary in relation to the mean circulation, bottom topography, and the nonlinearity of eddy dynamics. The gridded fields of remote sensing data have made satellite observations routinely accessible to general users for scientific and operational applications. The outlook for future development in ocean remote sensing is also discussed.

Download or read book Ocean Circulation and Climate written by Swadhin Behera and published by Elsevier Inc. Chapters. This book was released on 2013-10-22 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tropical oceans play important roles in the global climate system through ocean transports of heat and freshwater as well as ocean–atmosphere interactions. The developments in observational networks during recent decades have helped us to quantify the strength and variability of most of the ocean general circulations responsible for the transports. Those are discussed in detail in individual sections covering each tropical basin separately with a special emphasis on recent research results. Shallow overturning cells observed in all three tropical basins as well as the deep Atlantic meridional overturning circulation are such examples that are linked to ocean and climate variations on multiple timescales. In addition, tropical ocean–atmosphere interactions associated with oceanic planetary waves cause large-scale climate variations such as El Niño/Southern Oscillation (ENSO), Indian Ocean Dipole, Atlantic Niño, and ENSO Modoki. Recent advances in numerical modeling augmented by in situ and satellite observations are helping the research community to understand ocean process and to predict associated climate variations on seasonal to longer timescales.

This book was released on 2012-12-06 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most crucial but still very poorly understood topics of oceanographic science is the role of ocean processes in contributing to the dynamics of climate and global change. This book presents a series of high level lectures on the major categories of ocean/atmosphere processes. Three of these major issues are the focus of the lectures: (1) air--sea interaction processes; (2) water mass formation, dispersion and mixing; (3) general circulation, with specific emphasis on the thermohaline component. Global examples in the world ocean are provided and discussed in the lectures. In parallel, the Mediterranean Sea is a laboratory basin in providing analogues of the above global processes relevant to climate dynamics. They include the Mediterranean thermohaline circulation with its own `conveyor belt'; intermediate and deep water mass formation and transformations, dispersion and mixing. No other book in the field provides a review of fundamental lectures on these processes, coupled with global examples and their Mediterranean analogues.

Book Synopsis Ocean Circulation and Climate by : Scott C. Doney
Download or read book Ocean Circulation and Climate written by Scott C. Doney and published by Elsevier Inc. Chapters. This book was released on 2013-10-22 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean physics plays a central role in structuring the large-scale patterns and functioning of ocean ecosystems, and climate variability impacts marine biota in a wide variety of ways. Primary production by phytoplankton forms the base of the pelagic-ocean food web and is modulated by temperature, nutrient supply, light, and mixed layer depth. Temperature influences a host of organism physiological rates, and temperature and circulation are determining factors in the geographic ranges of many marine species. Climate variations alter predator–prey interactions, interspecies competition, the seasonal timing of biological events or phenology, the spread of diseases, parasites and invasive species, and the biogeochemical cycling of carbon, nutrients, and many trace chemicals. Ocean biology, in turn, can affect climate by influencing the atmospheric composition of radiatively important trace gases such as carbon dioxide, nitrous oxide, and dimethyl sulfide; chlorophyll also modifies the vertical absorption profile of solar radiation and thus influences sea-surface temperature and mixed layer depth. Based on historical observations, biological effects are already evident in response to anthropogenic ocean warming and sea-ice melt. Future climate change impacts are expected to grow in magnitude due to further warming and other physical changes as well as synergistic effects with other human stressors such as ocean acidification, deoxygenation, and coastal nutrient eutrophication.
