Download or read book Spectral Numerical Weather Prediction Models written by Martin Ehrendorfer and published by SIAM. This book was released on 2012-01-01 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of numerical weather prediction (NWP) focusing on the application of the spectral method in NWP models. The author illustrates the use of the spectral method in theory as well as in its application to building a full prototypical spectral NWP model, from the formulation of continuous model equations through development of their discretized forms to coded statements of the model. The author describes the implementation of a specific model - PEAK (Primitive-Equation Atmospheric Research Model Kernel) - to illustrate the steps needed to construct a global spectral NWP model. The book brings together all the spectral, time, and vertical discretization aspects relevant for such a model. It provides readers with information necessary to construct spectral NWP models; a self-contained, well-documented, coded spectral NWP model; and theoretical and practical exercises, some of which include solutions.

This book was released on 2006-07-11 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book An Introduction to Numerical Weather Prediction Techniques written by T. N. Krishnamurti and published by CRC Press. This book was released on 2018-05-11 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Numerical Weather Prediction Techniques is unique in the meteorological field as it presents for the first time theories and software of complex dynamical and physical processes required for numerical modeling. It was first prepared as a manual for the training of the World Meteorological Organization's programs at a similar level. This new book updates these exercises and also includes the latest data sets. This book covers important aspects of numerical weather prediction techniques required at an introductory level. These techniques, ranging from simple one-dimensional space derivative to complex numerical models, are first described in theory and for most cases supported by fully tested computational software. The text discusses the fundamental physical parameterizations needed in numerical weather models, such as cumulus convection, radiative transfers, and surface energy fluxes calculations. The book gives the user all the necessary elements to build a numerical model. An Introduction to Numerical Weather Prediction Techniques is rich in illustrations, especially tables showing outputs from each individual algorithm presented. Selected figures using actual meteorological data are also used. This book is primarily intended for senior-level undergraduates and first-year graduate students in meteorology. It is also excellent for individual scientists who wish to use the book for self-study. Scientists dealing with geophysical data analysis or predictive models will find this book filled with useful techniques and data-processing algorithms.

This book was released on 1999-01-01 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, numerical weather prediction models have progressed from finite difference methods to spectral methods in order to obtain more accurate forecasts in less computational time. A switch from "pure" finite difference to "pure" spectral techniques, however, may not be the best approach in all cases. Indeed, for some problems a mixed approach with finite difference approximations in one coordinate and spectral approximations in the remaining coordinates may provide comparably accurate results in less computational time than either pure method alone. This is particularly evident for the case of a hurricane where a state of near-circular symmetry typically prevails. For such a problem, a semi-spectral (SS) method using finite difference approximations in the radial direction and spectral methods in the azimuthal direction is a natural choice. While the effectiveness of pure methods for certain problems in fluid dynamics and atmospheric dynamics is well documented, comparatively little work has been undertaken to examine the effectiveness of SS schemes. This is particularly evident in problems concerning the vorticity dynamics of the hurricane near-core region. Because of the nearly circular flow of a strong hurricane, we hypothesize that SS formulations may prove useful in helping to elucidate the asymmetric vorticity dynamics in the hurricane's near-core region. This study examines the effectiveness of the semi-spectral approach for two classes of problems. The first problem concerns the redistribution of vorticity anomalies within a "master" vortex possessing a vorticity profile which decreases monotonically with radius. The second problem concerns barotropic instability, vortex breakdown, and vorticity mixing that is observed in mature hurricanes.

Book excerpt: Numerical Methods in Weather Prediction focuses on the numerical methods for solving problems of weather prediction and explains the aspect of the general circulation of the atmosphere. This book explores the development in the science of meteorology, which provides investigators with improved means of studying physical processes by mathematical stimulation. Organized into eight chapters, this book starts with an overview of the significant physical factors that are instrumental in enriching the theoretical models of weather prediction. This text then examines the system of hydrodynamic equations and the equation of heat transfer related to large-scale atmospheric processes. Other chapters consider the quasigeostrophic approximation model, which is the basis for concepts of the dynamics of atmospheric motions and instrumental in establishing the basic features and laws of evolution of meteorological variables as applied to large-scale processes. The final chapter deals with the adjustment of the humidity field. This book is a valuable resource for meteorologists.
