In response to Air Weather Service requirements, the Air Force Geophysics Lab has been involved in research in the development of mesoscale advection fog prediction techniques. A two-dimensional fog prediction model developed at the Naval Environmental Prediction Research Facility (NEPRF) was selected for evaluation because it can operate on a mini-computer of the size planned for the Air Force's Automated Weather Distribution System (AWDS). Six case studies developed by Calspan Advanced Technology Center were used to test the model's accuracy. These case studies covered a wide range of fog/stratus formation and dissipation stages. Four major weaknesses were identified in the model. The most important was that cloud tops increased in temperature through infrared radiative heat processes rather than decreased. The other weaknesses include lack of solar radiation processes, unreliable treatment of the height of mixed layer during stable conditions, and insufficient handling of vertical motions. The model may have potential in AWDS. However, these weaknesses must first be corrected.

Methods in Computational Physics, Volume 17: General Circulation Models of the Atmosphere is a five-chapter text that covers the fundamentals and application of general circulation models to solving practical problems related to the atmosphere. The first chapter describes the various options in modeling physical processes and computational procedures. The next two chapters illustrate the influence of practical considerations to the compromise between a detailed physical description and reasonable computing time. Other chapters outline the computational details of two different numerical schemes for general circulation models. These chapters particularly provide an in-depth analysis of finite difference methods by proceeding from general considerations of homogeneous incompressible flow to the fine details of the particular numerical scheme. The final chapter discusses the fundamentals of the alternative spectral method for a multilevel spectral model that illustrates the capability of that approach. This book is of value to geoscientists, mathematicians, and physicists.

Dealing with issues related to the modelling, monitoring and management of air pollution, this book includes papers presented at the 26th International Conference on Modelling, Monitoring and Management of Air Pollution. The papers from this conference continue a wide ranging collection of high quality research works that develop the fundamental science of air pollution. Air pollution issues remain one of the most challenging problems facing society. The scientific knowledge derived from well-designed studies needs to be allied with further technical and economic studies in order to ensure cost effective and efficient mitigation. Increasingly, it is being recognised that the outcome of such research needs to be contextualised within well formulated communication strategies that help policy makers and citizens to understand and appreciate the risks and rewards arising from air pollution management. Details of the wide spread nature of the air pollution phenomena and in depth explorations of their impacts on human health and the environment are covered in this book.
