Available in PDF, EPUB and Kindle. Book excerpt: Mathematical modeling of atmospheric composition is a formidable scientific and computational challenge. This comprehensive presentation of the modeling methods used in atmospheric chemistry focuses on both theory and practice, from the fundamental principles behind models, through to their applications in interpreting observations. An encyclopaedic coverage of methods used in atmospheric modeling, including their advantages and disadvantages, makes this a one-stop resource with a large scope. Particular emphasis is given to the mathematical formulation of chemical, radiative, and aerosol processes; advection and turbulent transport; emission and deposition processes; as well as major chapters on model evaluation and inverse modeling. The modeling of atmospheric chemistry is an intrinsically interdisciplinary endeavour, bringing together meteorology, radiative transfer, physical chemistry and biogeochemistry, making the book of value to a broad readership. Introductory chapters and a review of the relevant mathematics make this book instantly accessible to graduate students and researchers in the atmospheric sciences.

This book was released on 1987 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the culmination of a three-year development and testing effort on a two-dimensional (x-y plane) surface-layer windflow model for complex terrain. The model was acquired from the U.S. Army Atmospheric Sciences Laboratory (ASL) at White Sands, New Mexico in 1984. The version of the model described in this report has been adapted to run using real time data on both the Zenith-100 and IBM-compatible Zenith-248 computers. The model accepts input of a single surface observation (or forecast) of wind, temperature, and cloud cover, and uses this information along with terrain information and the date/time to diagnose the surface-layer stability. The model then performs a variational analysis of the windfield, adjusting the winds through a relaxation technique until the windfield conforms to effects of topography, stability, ambient flow conditions, and mass continuity. The model is designed to produce high-resolution wind analyses, typically running on domains on the order of 10 X 10 km, with horizontal grid spacing of 100 to 200 m. We present an overview of potential military and nonmilitary uses for the model, and describe the relevant physics and computer architecture of the model and its two utility plotting routines. A user's guide, included here as Section 4, is primarily aimed at providing operational users such as forecasters some guidelines for using the model and interpreting the output. Finally, we present the results of an operational test of the model in support of Army Special Forces operations at Ft. Devens, Massachusetts. The test results illustrate the model's potential as a tactical weather support tool for low-level aviation and paradrop activities.

This book was released on 2012-12-06 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: The realism of large scale numerical ocean models has improved dra matically in recent years, in part because modern computers permit a more faithful representation of the differential equations by their algebraic analogs. Equally significant, if not more so, has been the improved under standing of physical processes on space and time scales smaller than those that can be represented in such models. Today, some of the most challeng ing issues remaining in ocean modeling are associated with parameterizing the effects of these high-frequency, small-space scale processes. Accurate parameterizations are especially needed in long term integrations of coarse resolution ocean models that are designed to understand the ocean vari ability within the climate system on seasonal to decadal time scales. Traditionally, parameterizations of subgrid-scale, high-frequency mo tions in ocean modeling have been based on simple formulations, such as the Reynolds decomposition with constant diffusivity values. Until recently, modelers were concerned with first order issues such as a correct represen tation of the basic features of the ocean circulation. As the numerical simu lations become better and less dependent on the discretization choices, the focus is turning to the physics of the needed parameterizations and their numerical implementation. At the present time, the success of any large scale numerical simulation is directly dependent upon the choices that are made for the parameterization of various subgrid processes.

This book was released on 2012-12-06 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of convection in geophysical flows constitute an advanced and rapidly developing area of research that is relevant to problems of the natural environment. During the last decade, significant progress has been achieved in the field as a result of both experimental studies and numerical modelling. This led to the principal revision of the widely held view on buoyancy-driven turbulent flows comprising an organised mean component with superimposed chaotic turbulence. An intermediate type of motion, represented by coherent structures, has been found to play a key role in geophysical boundary layers and in larger scale atmospheric and hydrospheric circulations driven by buoyant forcing. New aspects of the interaction between convective motions and rotation have recently been discovered and investigated. Extensive experimental data have also been collected on the role of convection in cloud dynamics and microphysics. New theoretical concepts and approaches have been outlined regarding scaling and parameterization of physical processes in buoyancy-driven geophysical flows. The book summarizes interdisciplinary studies of buoyancy effects in different media (atmosphere and hydrosphere) over a wide range of scales (small scale phenomena in unstably stratified and convectively mixed layers to deep convection in the atmosphere and ocean), by different research methods (field measurements, laboratory simulations, numerical modelling), and within a variety of application areas (dispersion of pollutants, weather forecasting, hazardous phenomena associated with buoyant forcing).
Download or read book Sensitivity Tests of a Surface layer Windflow Model to Effects of Stability and Vegetation written by John M. Lanicci and published by . This book was released on 1985 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines the sensitivity of surface-layer windflow over gently rolling terrain to different stability conditions, both with and without the effects of vegetation used to modify terrain heights and determine surface roughness. The numerical model used produces simulations of surface-layer windflow by using Gauss's Principle of Least Constraints to allow an initially uniform windfield to adjust to topography and buoyancy forces while conserving mass. The model experiments used simulated meteorological data (at only one observation point) and detailed terrain and vagetation data (on a 51-by-51 grid with 100 m spacing) for an area covering 5 by 5 km over the Fort Polk Military Reservation in Louisiana. Results show that the model simulates topographically induced flows such as cold air drainage and upslope flow, despite the simple physics employed. We also show that the presence to tall vegetation over the area (mainly coniferous and deciduous trees) alters the flow patterns under various stability conditions. These effects are shown to be caused primarily by changes in the area of chemical transport and diffusion, because they mean that even gently rolling terrain influences the surface windflow, and that tall vegetation has a considerable influence as well.
