Available in PDF, EPUB and Kindle. Book excerpt: The dynamics of the ocean surface boundary layer are examined using theory, high-resolution moored observations from the equatorial Atlantic ocean, and idealized modeling. An approximate solution is found for the ocean response to wind-forcing in the presence of baroclinic pressure gradients, surface wave shear, and spatially varying turbulent mixing. The manner in which these parameters modify the classic physical model of the wind-forced ocean is discussed, and estimates of their spatial distribution are provided. Next, the role of time-varying shear in determining the near-surface eddy viscosity is assessed using velocity observations from the equatorial Atlantic, and the implications for several simple parameterizations are considered. These observations are then utilized to provide a first in situ observational assessment of the diurnal cycle of shear and stratification in the equatorial Atlantic, demonstrating how mixed-layer dynamics modulate the diurnal cycle of sea surface temperature, coupling the dynamic and thermodynamic responses. Further, these results suggest the existence of a deep-cycle turbulence layer in the equatorial Atlantic, providing a complementary perspective on similar recent work from the Pacific. Finally, the effect of time-varying eddy viscosity on the low-frequency wind-driven flow is assessed using theory and idealized modeling, providing a new conceptual tool for understanding the dynamics of the near-surface ocean, and for guiding the interpretation of observations. A particular focus throughout this thesis is the role of ocean dynamics in determining the near-surface ocean response to surface atmospheric fluxes.

This book was released on 2013-04-17 with total page 573 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 1980's a wealth of information was reported from field and laboratory experiments in order to validate andlor modify various aspects of the surface layer Monin-Obukhov (M-O) similarity theory for use over the sea, and to introduce and test new concepts related to high resolution flux magnitudes and variabilities. For example, data from various field experiments conducted on the North Sea, Lake Ontario, and the Atlantic experiments, among others, yielded information on the dependence of the flux coefficients on wave state. In all field projects, the usual criteria for satisfying M-O similarity were applied. The assumptions of stationarity and homogeneity was assumed to be relevant over both small and large scales. In addition, the properties of the outer layer were assumed to be "correlated" with properties of the surface layer. These assumptions generally required that data were averaged for spatial footprints representing scales greater than 25 km (or typically 30 minutes or longer for typical windspeeds). While more and more data became available over the years, and the technology applied was more reliable, robust, and durable, the flux coefficients and other turbulent parameters still exhibited significant unexplained scatter. Since the scatter did not show sufficient reduction over the years to meet customer needs, in spite of improved technology and heavy financial investments, one could only conclude that perhaps the use of similarity theory contained too many simplifications when applied to environments which were more complicated than previously thought.

This book was released on 2006-03-13 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until the 1980s, a tacit agreement among many physical oceanographers was that nothing deserving attention could be found in the upper few meters of the ocean. The lack of adequete knowledge about the near-surface layer of the ocean was mainly due to the fact that the widely used oceanographic instruments (such as bathythermographs, CTDs, current meters, etc.) were practically useless in the upper few meters of the ocean. Interest in the ne- surface layer of the ocean rapidly increased along with the development of remote sensing techniques. The interpretation of ocean surface signals sensed from satellites demanded thorough knowledge of upper ocean processes and their connection to the ocean interior. Despite its accessibility to the investigator, the near-surface layer of the ocean is not a simple subject of experimental study. Random, sometimes huge, vertical motions of the ocean surface due to surface waves are a serious complication for collecting quality data close to the ocean surface. The supposedly minor problem of avoiding disturbances from ships’ wakes has frustrated several generations of oceanographers attempting to take reliable data from the upper few meters of the ocean. Important practical applications nevertheless demanded action, and as a result several pioneering works in the 1970s and 1980s laid the foundation for the new subject of oceanography – the near-surface layer of the ocean.

This book was released on 2022-10-28 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes achievements of the study on circulation and air–sea interaction and development of the ocean observation network in the South China Sea in the last 20 years, thus serving as a comprehensive reference book to understand the dynamic environment in the SCS. It consists of seven chapters, briefly reviewing our understanding of the SCS circulation and air–sea interaction in chapter 1, then describing in detail the upper layer circulation from large scale (SCS through flow, SCS western boundary current, etc.), to meso- and submeso-scale in Chapters 2 and 5, dilute river plume and coastal upwelling over the shelf in Chapter 3, deep ocean circulation in Chapter 4, tropical cyclone activities and air–sea flux at the interface in Chapter 6, and the construction of the observation network and database in Chapter 7. Besides the basic features of these physical processes, the book also discusses their variations and fundamental dynamics. Thus, it is written in a way that meets the different information demands from researchers working in various marine related fields.

Download or read book Air Sea Interaction written by F. Dobson and published by Springer. This book was released on 1980-10-31 with total page 824 pages. 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'.

Available in PDF, EPUB and Kindle. Book excerpt: During the Conference on Air-Sea Interaction in January 1986, it was suggested to me by David Larner of Reidel Press that it may be timely for an updated compendium of air-sea interaction theory to be organized, developed, and published. Many new results were emerging at the time, i.e., results from the MARSEN, MASEX, MILDEX, and TOWARD field projects (among others) were in the process of being reported and/or published. Further, a series of new experiments such as FASINEX and HEXOS were soon to be conducted in which new strides in our knowledge of air-sea fluxes would be made. During the year following the discussions with David Larner, it became apparent that many of the advances in air-sea interaction theory during the 1970s and 1980s were associated with sponsor investments in satellite oceanography and, in particular, remote sensing research. Since ocean surface remote sensing, e.g., scatterometry and SAR, requires intimate knowledge of ocean surface dynamics, advances in remote sensing capabilities required coordinated research in air-sea fluxes, wave state, scattering theory, sensor design, and data exploitation using environmental models. Based on this interplay of disciplines, it was decided that this book be devoted to air sea interaction and remote sensing as multi-disciplinary activities.

Available in PDF, EPUB and Kindle. Book excerpt: Little work has been done to explore air-sea interaction and upper ocean dynamics in very light winds, and few observations are available that describe the mesoscale and smaller scale horizontal variability of the upper ocean and lower atmosphere in such conditions. Therefore, observational components of this program will investigate the temporal and spatial evolution of the Coupled Boundary Layers (CBLs) over vertical scales of centimeters to hundreds of meters, horizontal scales of 10 meters to 10's of kilometers, and time scales of minutes to months. Mesoscale models, large eddy simulations (LES), and direct numerical simulations (DNS) will provide nowcasts, forecasts, and simulations over similar scales. The numerical results will provide a context for interpreting our measurements, while our measurements will provide a means to initialize and evaluate the estimates of turbulent fluxes and dissipation rates calculated by these models. The objective of the Coupled Boundary Layers and Air-Sea Transfer (CBLAST) DRI Program Office is to assist the CBLAST principal investigators in their research and publication efforts in all aspects of the program.

Bala Subrahamanyam and published by GRIN Verlag. This book was released on 2011-08-26 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2003 in the subject Physics - Applied physics, grade: None, Mahatma Gandhi University (Space Physics Laboratory - Vikram Sarabhai Space Centre, Thiruvananthrapuram - 695 022), course: Atmospheric Sciences, language: English, abstract: The Atmospheric Boundary Layer (ABL) over the oceanic surface is commonly referred to as the Marine Atmospheric Boundary Layer (MABL) and it can be considered as the turbulent region in the immediate vicinity of the oceanic surface. The major features that distinguish the ABL over ocean from its land counterpart are the wet, mobile, lower boundary in addition to certain ocean-specific thermodynamic and dynamic characteristics. The structure and characteristics of the MABL and its interactions with the oceanic surface and the overlying free atmosphere are known mainly as a result of a synergistic combination of observational studies, numerical and laboratory simulations, and dimensional analysis. Our present knowledge and understanding of the MABL over various oceanic regions of the globe comes from the experience and expertise acquired during various field experiments. The present thesis aims at improving our understanding of the structural characteristics of the MABL and its associated dynamics over the data-sparse region of western tropical Indian Ocean by making use of the meteorological data collected onboard Oceanic Research Vessel (ORV) Sagar Kanya and Kaashidhoo Climate Observatory (KCO) during the Intensive Field Phase (IFP-99) of the Indian Ocean Experiment (INDOEX).
