Book Description
This is an introductory textbook on global spectral modeling designed for senior-level undergraduates and possibly for first-year graduate students. This text starts with an introduction to elementary finite-difference methods and moves on towards the gradual description of sophisticated dynamical and physical models in spherical coordinates. Computational aspects of the spectral transform method, the planetary boundary layer physics, the physics of precipitation processes in large-scale models, the radiative transfer including effects of diagnostic clouds and diurnal cycle, the surface energy balance over land and ocean, and the treatment of mountains are some issues that are addressed. The topic of model initialization includes the treatment of normal modes and physical processes. A concluding chapter covers the spectral energetics as a diagnostic tool for model evaluation. This revised second edition of the text also includes three additional chapters. Chapter 11 deals with the formulation of a regional spectral model for mesoscale modeling which uses a double Fourier expansion of data and model equations for its transform. Chapter 12 deals with ensemble modeling. This is a new and important area for numerical weather and climate prediction. Finally, yet another new area that has to do with adaptive observational strategies is included as Chapter 13. It foretells where data deficiencies may reside in model from an exploratory ensemble run of experiments and the spread of such forecasts.

Book Description
"This volume is based on the "School/Workshop on Linear Time, Branching Time and Partial Order in Logics and Models for Concurrency" organized by the editors and held in the period May 30-June 3, 1988 at Noordwijkerhout, The Netherlands. The School/Workshop was an activity of the project REX - Research and Education in Concurrent Systems. The volume contains tutorials and research contributions to the three approaches - linear time, - branching time, and - partial order in semantics and proof theory of concurrent programs by the main specialists in this field. It promotes an in-depth understanding of the relative merits and disadvantages of these three approaches. An introduction to the recent literature on the subject is provided by the invited research contributions.''--Publisher's website.

Book Description
This is an introductory text on numerical weather prediction (numerically modelling the general circulation of the atmosphere), utilizing the spectral transform method. The book covers finite difference methods and time-differencing schemes; the theoretical development of the spectral transform method (using spherical surfaces rather than grids for determining variation in the elements of weather); physical processes; current issues in dynamical and physical initiation; and data analysis. Several practical examples of the spectral transform method are included.

Book Description
General circulation models (GCMs), which define the fundamental dynamics of atmospheric circulation, are nowadays used in various fields of atmospheric science such as weather forecasting, climate predictions and environmental estimations. The Second Edition of this renowned work has been updated to include recent progress of high resolution global modeling. It also contains for the first time aspects of high-resolution global non-hydrostatic models that the author has been studying since the publication of the first edition. Some highlighted results from the Non-hydrostatic ICosahedral Atmospheric Model (NICAM) are also included. The author outlines the theoretical concepts, simple models and numerical methods for modeling the general circulation of the atmosphere. Concentrating on the physical mechanisms responsible for the development of large-scale circulation of the atmosphere, the book offers comprehensive coverage of an important and rapidly developing technique used in the atmospheric science. Dynamic interpretations of the atmospheric structure and their aspects in the general circulation model are described step by step.

Book Description
This book describes the methods used to construct general circulation models of the atmosphere, and how such models perform in applications relating to the real climate and environmental systems. The author describes the fundamental dynamics of the atmospheric circulation, modelling of the general circulation, and applications of GCMs. The book consists of three parts: - Part 1 summarizes the physical processes involved, including basic equations, waves and instabilities; - Part 2 covers atmospheric structures, including various types of one- and two-dimensional structures and circulations; - Part 3 describes the basic notions for construction of general circulation models of the atmosphere and their applications. Atmospheric Circulation Dynamics and General Circulation Methods includes an appendix incorporating the basic data and mathematical formulae required to enable readers to construct GCMs for themselves.

Book Description
This textbook provides a fast-track pathway to numerical implementation of phase-field modeling—a relatively new paradigm that has become the method of choice for modeling and simulation of microstructure evolution in materials. It serves as a cookbook for the phase-field method by presenting a collection of codes that act as foundations and templates for developing other models with more complexity. Programming Phase-Field Modeling uses the Matlab/Octave programming package, simpler and more compact than other high-level programming languages, providing ease of use to the widest audience. Particular attention is devoted to the computational efficiency and clarity during development of the codes, which allows the reader to easily make the connection between the mathematical formulism and the numerical implementation of phase-field models. The background materials provided in each case study also provide a forum for undergraduate level modeling-simulations courses as part of their curriculum.
