Book Description :

This chapter reports on the spatial scale of mesoscale systems, and then presents examples of mesoscale atmospheric systems. They are classed into two types, terrain- and physiographically-induced mesoscale systems, and mesoscale systems primarily forced through lateral boundaries or from internal atmospheric instabilities. Mesoscale model studies of Mars, Titan, and Venus are also introduced. The different types of dynamic downscaling to the regional and mesoscale from global models and reanalyses are presented. The use of mesoscale models to assess air quality is discussed.

Book Description :

This chapter provides a framework to assess the quantitative accuracy of numerical computational tools that are used to model advection, subgrid-scale fluxes, the pressure gradient force, and the Coriolis effect. Exact solutions are presented for linear forms of these terms. Nonlinear effects are also discussed including the concept of aliasing in which information is transferred between spatial scales. Among the results, it is shown that two grid increments are required to minimally resolve a modeled field with at least four increments in each spatial direction (and probably more) required to adequately resolve the modeled variables.

Book Description :

This chapter presents a new approach to parameterize physical processes in atmospheric models. Referred to as a “look-up table” (LUT) approach, it catalogs them into LUTs used within traditional parameterizations, to replace traditional parameterizations, and for the integrated parameterized effects that result in diabatic heating and cooling and other physical processes.

Book Description :

This chapter shows how comparisons with analytic, other numerical models, different model approximations, and observations can be used to assess the robustness of the model calculations. Also, for this purpose, model budgets for mass, energy and momentum are shown to be essential tests of model skill. The tank model is used to illustrate how these budgets can be applied for assessing the accuracy in the computation of the mass and energy budgets.

This chapter discusses physical and analytical modeling. The study of realistic wind tunnel simulations of mesoscale atmospheric flows is presented. External and internal gravity waves when a vertical density discontinuity occurs are derived for idealized tank models. Internal gravity waves, sound waves, and inertial waves are derived for a continuously stratified atmosphere. The validity of the hydrostatic approximation is examined quantitatively using a sea-breeze model. The role of compressibility is discussed.

The foundation for any model is a set of conservation principles. For mesoscale atmospheric models, these principles are conservation of mass, conservation of heat, conservation of motion, conservation of water, the conservation of other gaseous and aerosol materials, and an equation of state.

This chapter presents the mathematical methodology of using tensors to transform a Cartesian coordinate system to other types of coordinate systems. The emphasis is on the development of generalized vertical coordinate systems including those based on pressure, potential temperature, and terrain-following. Specific examples of how the coordinate system can facilitate improved understanding of atmospheric flows is presented.

‘Mesoscale Modelling for Meteorological and Air Pollution Applications’ combines the fundamental and practical aspects of mesoscale air pollution and meteorological modelling. Providing an overview of the fundamental concepts of air pollution and meteorological modelling, including parameterization of key atmospheric processes, the book also considers equally important aspects such as model integration, evaluation concepts, performance evaluation, policy relevance and user training.

Book Description :

This chapter discusses how the fundamental conservation equations can be simplified using scale analysis. These simplifications can result in the conversion of a prognostic conservation equation to a diagnostic equation. Such simplifications are used, for example, to create the replacement of the vertical equation-of-motion with the hydrostatic, and the replacement of the prognostic equation for mass with the anelastic and incompressible so-called “continuity” equations.

Book Description :

This book, as the outcome of the COST-728/NetFAM workshop, focuses on the following main topics: 1) on-line coupled meteorology-chemistry modelling with two-way feedbacks, 2) off-line coupled modelling and interfaces, 3) validation and case studies including air quality related episodes, and 4) integration of atmospheric chemical transport (ACT) models with numerical weather prediction (NWP). This book is one of the first attempts to give an overall look on such integrated meso-meteorology and chemistry modelling approach. It reviews the current situation with the on-line and off-line coupling of mesoscale meteorological and ACT models worldwide as well as discusses advantages and shortcomings, best practices, and gives recommendations for on-line and off-line coupling of NWP and ACT models, implementation strategy for different feedback mechanisms, direct and indirect effects of aerosols and advanced interfaces between both types of models. The book is oriented towards numerical weather prediction and air quality modelling communities.

Book Description :

Accurate predictions of air quality and atmospheric dispersion at high spatial resolution rely on high fidelity predictions of mesoscale meteorological fields that govern transport and turbulence in urban areas. However, mesoscale meteorological models do not have the spatial resolution to directly simulate the fluid dynamics and thermodynamics in and around buildings and other urban structures that have been shown to modify micro- and mesoscale flow fields (e.g., see review by Bornstein 1987). Mesoscale models therefore have been adapted using numerous approaches to incorporate urban effects into the simulations (e.g., see reviews by Brown 2000 and Bornstein and Craig 2002). One approach is to introduce urban canopy parameterizations to approximate the drag, turbulence production, heating, and radiation attenuation induced by sub-grid scale buildings and urban surface covers (Brown 2000). Preliminary results of mesoscale meteorological and air quality simulations for Houston (Dupont et al. 2004) demonstrated the importance of introducing urban canopy parameterizations to produce results with high spatial resolution that accentuates variability, highlights important differences, and identifies critical areas. Although urban canopy parameterizations may not be applicable to all meteorological and dispersion models, they have been successfully introduced and demonstrated in many of the current operational and research mode mesoscale models, e.g., COAMPS (Holt et al. 2002), HOTMAC (Brown and Williams 1998), MM5 (e.g., Otte and Lacser 2001; Lacser and Otte 2002; Dupont et al. 2004), and RAMS (Rozoff et al. 2003). The primary consequence of implementing an urban parameterization in a mesoscale meteorological model is the need to characterize the urban terrain in greater detail. In general, urban terrain characterization for mesoscale modeling may be described as the process of collecting datasets of urban surface cover physical properties (e.g., albedo, emissivity) and morphology (i.e., ground elevation, building and tree height and geometry characteristics) and then processing the data to compute physical cover and morphological parameters. Many of the surface cover and morphological parameters required for mesoscale meteorological models are also needed by atmospheric dispersion models. Thus, most of the discussion below is relevant to both types of modeling. In this paper, the term urban morphological analysis will be used to define the component of urban terrain characterization concerned with the morphological parameters. Furthermore, the focus will be building morphological parameters; therefore, the term urban morphological analysis will refer exclusively to the task of inventorying, computing or estimating building morphological parameters. Several approaches to perform urban morphological analysis exist; however, all have in common three types of practice issues related to the uncertainty of (1) data, (2) parameter definitions and calculation methods, and (3) extrapolation techniques. The objective of this paper is to describe the state-of-the-practice of urban morphological analysis by reviewing the primary approaches presented in the literature and outlining and commenting on key aspects of the three types of practice issues listed above.
