Available in PDF, EPUB and Kindle. Book excerpt: The slope and curvature distributions of wind waves along two principal axes (upwind-downwind and crosswind) have been measured in a laboratory tank under various wind velocities. In both directions, the slope distributions are very closely Gaussian, and the components of the mean-square water-surface slope vary logarithmically with the friction velocity of the wind. As the wind velocity increases, the ratio between these two components increases and falls between 0.5 and 0.6 at high wind velocities in the gravity-governing regime of wind-wave interaction. The radius of water-surface curvature, along either direction of measurement, is found to be, generally, greater at a steeper viewing angle from the normal to the mean water surface. The average radius of curvature of the disturbed surface varies inversely with the friction velocity of the wind. The ratio between the upwind-downwind and crosswind components of the average radius of curvature is unity at all wind velocities, indicating that the wind-disturbed water surface is isotropic on the smallest scale.

Available in PDF, EPUB and Kindle. Book excerpt: The wind-disturbed water surface consists of waves of various lengths moving at various speeds. There is increasing interest in determining the statistical properties of the microstructure of such a surface. Measurement of the curvature distributions of wind waves viewed from different angles is helpful for understanding nonlinear interaction between ripples and carrier waves, and is important for interpreting reflection and back-scattering from the sea surface. In the present study, both slope and curvature distributions of the disturbed water surface under various wind conditions in a laboratory tank are simultaneously and systematically measured from all inclinations to the mean water surface, but in a plane containing the wind direction and perpendicular to the water surface.

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.

Book excerpt: The microstructure of the wind-disturbed water surface, characterized by surface-slope and surface-curvature distributions is studied with a newly-developed optical instrument. The measurements show systematically some features of these distributions under various wind conditions, and are correlated with the results of airflow boundary-layer surveys. Two regimes of equilibrium with different mechanisms for limiting wave growth are also discussed. In addition, with a turbulent wind, the present laboratory results exhibit variation of the mean square slope with the shear velocity similar to older oceanic data, suggesting possibility of the laboratory simulation of the microstructure of the air-sea interface.

Available in PDF, EPUB and Kindle. Book excerpt: Basic Developments in Fluid Dynamics, Volume 2 focuses on the developments, approaches, methodologies, reactions, and processes involved in fluid dynamics, including sea motion, wave interactions, and motion of spheres in a viscous fluid. The selection first offers information on inviscid cavity and wake flows and weak-interaction theory of ocean waves. Discussions focus on steady and unsteady cavity flows, radiation balance, theory of weak interactions in random fields, interactions between gravity waves and the atmosphere, and interactions within the ocean. The text then examines low Reynolds number flows, including fundamentals, expansion procedures, stokes in flow solutions, flows with a free surface, and compressible flows. The selection is a dependable source of information for graduate students, research workers, and readers interested in fluid dynamics.
