This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The turbulent fluxes of momentum, mass, and energy across the ocean-atmosphere boundary are fundamental to our understanding of a myriad of geophysical processes, such as wind-wave generation, oceanic circulation, and air-sea gas transfer. In order to better understand these fluxes, empirical relationships were developed to quantify the interfacial exchange rates in terms of easily observed parameters (e.g., wind speed). However, mounting evidence suggests that these empirical formulae are only valid over the relatively narrow parametric space, i.e. open ocean conditions in light to moderate winds. Several near-surface processes have been observed to cause significant variance in the air-sea fluxes not predicted by the conventional functions, such as a heterogeneous surfaces, swell waves, and wave breaking. Further study is needed to fully characterize how these types of processes can modulate the interfacial exchange; in order to achieve this, a broad investigation into air-sea coupling was undertaken. The primary focus of this work was to use a combination of field and laboratory observations and numerical modeling, in regimes where conventional theories would be expected to breakdown, namely: the nearshore and in very high winds. These seemingly disparate environments represent the marine atmospheric boundary layer at its physical limit. In the nearshore, the convergence of land, air, and sea in a depth-limited domain marks the transition from a marine to a terrestrial boundary layer. Under extreme winds, the physical nature of the boundary layer remains unknown as an intermediate substrate layer, sea spray, develops between the atmosphere and ocean surface. At these ends of the MABL physical spectrum, direct measurements of the near-surface processes were made and directly related to local sources of variance. Our results suggest that the conventional treatment of air-sea fluxes in terms of empirical relationships developed from a relatively narrow set of environmental conditions do not generalize to the coastal and extreme wind environments. This body of work represents a multi-faceted approach to understanding physical air-sea interactions in varied regimes and using a wide array of investigatory methods.
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.
Book Synopsis Advances in Coastal and Ocean Engineering by : M. Brocchini
Download or read book Advances in Coastal and Ocean Engineering written by M. Brocchini and published by World Scientific. This book was released on 2002 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a useful source of ideas and information for scientists whose work involves understanding and modelling turbulent flows with free surfaces. It has the following merits: (1) It provides a framework for developing the analysis of this field, which, although important, has received only limited study; (2) It recognizes the importance of the two-phase nature of strongly disturbed free surface flows, with both natural and technological applications; (3) It suggests possible lines of future research (especially experimental) to quantify the characteristics of flow regimes which are mainly known qualitatively at present.

Book Synopsis Physical Oceanography of the Baltic Sea by : Matti Leppäranta
Download or read book Physical Oceanography of the Baltic Sea written by Matti Leppäranta and published by Springer Science & Business Media. This book was released on 2009-03-20 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Baltic Sea oceanographic research community is wide and the research history is over 100 years old. Nevertheless, there is still no single, coherent book on the physical oceanography of the Baltic Sea as a whole. There is a strong need for such a book, coming from working oceanographers as well as the university teaching programmes in advanced undergraduate to graduate levels. In the regional conference series in physical oceanography (Baltic Sea Science Conference, Baltic Sea Oceanographers' conference, Baltex-conferences) about 500 scientists take part regularly. Even more scientists work in the fields of marine biology, chemistry and the environment, and they need information on the physics of the Baltic Sea as well. There are nine countries bordering on the Baltic Sea and five more in the runoff area. The Baltic Sea as a source of fish, means of transportation and leisure activities is highly important to the regional society. In the runoff area there are a total of 85 million people. Research and protection strategies need to be developed, as the Baltic Sea is probably the most polluted sea in the world. Since the Baltic Sea has become an inner sea of the EU (apart from small shore parts of Russia in Petersburg and Kaliningrad), it is anticipated that the importance of the region will consequently rise. The book will arouse interest among students, scientists and decision makers involved with the Baltic problems. It will also give important background information for those working with biogeochemical processes in the Baltic Sea, because the physical forcing for those processes is of vital importance.
Book Synopsis The Impact of Air-sea Coupling on Simulating SST Variability in the California Current System by : Daniel Burton Walton
Download or read book The Impact of Air-sea Coupling on Simulating SST Variability in the California Current System written by Daniel Burton Walton and published by . This book was released on 2012 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here we show that air-sea coupling significantly impacts the simulation of sea surface temperature (SST) variability in the California Current System (CCS). Previous work has shown important differences between coupled and uncoupled models in simulating coastal SST, but only using empirical coupling or idealized scenarios. We compare the output of the UCLA Mesoscale Coupled Model to the output of a similar but uncoupled model over the CCS. These high resolution, realistic regional models have identical coastlines, bathymetry, and topography. They are forced at the boundaries by reanalysis data over the historical period 1981-1990. This model setup allows us to evaluate how including air-sea coupling impacts the accuracy of our simulation by comparing our model output to buoy observations. Both the spatial patterns and the amount of variability are more realistic in the coupled model, which is likely due to improved simulation of internal variability.

Available in PDF, EPUB and Kindle. Book excerpt: During the past decade, man's centuries-old interest in marine me teorology and oceanography has broadened. Ocean and atmosphere are now treated as coupled parts of one system; the resulting interest in air-sea interaction problems has led to a rapid growth in the sophistication of instruments and measurement techniques. This book has been designed as a reference text which describes, albng with the instruments themselves, the accumulated practical experi ence of experts engaged in field observations of air-sea interac tions. It is meant to supplement rather than replace manuals on standard routine observations or instnunentation handbooks. At the inception a textbook was planned, which would contain only well tested methods and instruments. It was quickly discovered that for the book to be useful many devices and techniques would have to be included which are still evolving rapidly. The reader is therefore cautioned to take nothing in these pages for granted. Certainly, every contributor is an expert, but while some are back ed up by generations of published work, others are pioneers. The choice of topics, of course, is debatable. The types of observa tions included are not exhaustive and topics such as marine aero sols and radio-tracers are omitted, as was the general subject of remote sensing, which was felt to be too broad and evol ving too rapidly. The guideline adopted in limiting size was maximum use fulness to 'a trained experimentalist new to the field'.

This book was released on 2013 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: We use a comprehensive observational ensemble to assess the modern-day IPSL model representation of turbulent air-sea fluxes at large, climatological scales in the intertropical region. We consider the surface fluxes, as well as their associated meteorological state variables. In a first step, we create estimates of the observational uncertainties, and use them to highlight the significant biases in the atmospheric component of IPSL-CM5A, when forced with observational sea surface temperatures. In a second step, we apply the same methodology to the evaluation of several versions of the coupled IPSL model from CM4 to CM5B and assess flux-related differences due to ocean-atmosphere coupling, changes in horizontal resolution, surface albedo adjustment, and historical model development. Finally, we discuss methodological aspects of model evaluation, as well as the possible generalization of the relationship between coupled and uncoupled model biases found for the IPSL-CM5A model.
Book Synopsis The Interaction of Ocean Waves and Wind by : Peter Janssen
Download or read book The Interaction of Ocean Waves and Wind written by Peter Janssen and published by Cambridge University Press. This book was released on 2004-10-28 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was published in 2004. The Interaction of Ocean Waves and Wind describes in detail the two-way interaction between wind and ocean waves and shows how ocean waves affect weather forecasting on timescales of 5 to 90 days. Winds generate ocean waves, but at the same time airflow is modified due to the loss of energy and momentum to the waves; thus, momentum loss from the atmosphere to the ocean depends on the state of the waves. This volume discusses ocean wave evolution according to the energy balance equation. An extensive overview of nonlinear transfer is given, and as a by-product the role of four-wave interactions in the generation of extreme events, such as freak waves, is discussed. Effects on ocean circulation are described. Coupled ocean-wave, atmosphere modelling gives improved weather and wave forecasts. This volume will interest ocean wave modellers, physicists and applied mathematicians, and engineers interested in shipping and coastal protection.
