This book surveys recent developments in numerical techniques for global atmospheric models. It is based upon a collection of lectures prepared by leading experts in the field. The chapters reveal the multitude of steps that determine the global atmospheric model design. They encompass the choice of the equation set, computational grids on the sphere, horizontal and vertical discretizations, time integration methods, filtering and diffusion mechanisms, conservation properties, tracer transport, and considerations for designing models for massively parallel computers. A reader interested in applied numerical methods but also the many facets of atmospheric modeling should find this book of particular relevance.

The geosciences, particularly numerical weather prediction, are demanding the highest levels of available computer power. The European Centre for Medium-Range Weather Forecasts, with its experience in using supercomputers in this field, organises every second year a workshop bringing together manufacturers, computer scientists, researchers and operational users to share their experiences and to learn about the latest developments. This book reports on the November 2000 workshop. It provides an excellent overview of the latest achievements in, and plans for the use of, new parallel techniques in meteorology, climatology and oceanography. Contents: Research and Development of the Earth Simulator (K Yoshida & S Shingu); Parallel Computing at Canadian Meteorological Centre (J-P Toviessi et al.); Parallel Elliptic Solvers for the Implicit Global Variable-Resolution Grid-Point GEM Model: Iterative and Fast Direct Methods (A Qaddouri & J Ct(r)); IFS Developments (D Dent et al.); Performance of Parallelized Forecast and Analysis Models at JMA (Y Oikawa); Building a Scalable Parallel Architecture for Spectal GCMS (T N Venkatesh et al.); Semi-Implicit Spectral Element Methods for Atmospheric General Circulation Models (R D Loft & S J Thomas); Experiments with NCEP's Spectral Model (J-F Estrade et al.); The Implementation of I/O Servers in NCEP's ETA Model on the IBM SP (J Tuccillo); Implementation of a Complete Weather Forecasting Suite on PARAM 10 000 (S C Purohit et al.); Parallel Load Balance System of Regional Multiple Scale Advanced Prediction System (J Zhiyan); Grid Computing for Meteorology (G-R Hoffmann); The Requirements for an Active Archive at the Met Office (M Carter); Intelligent Support for High I/O Requirements of Leading Edge Scientific Codes on High-End Computing Systems OCo The ESTEDI Project (K Kleese & P Baumann); Coupled Marine Ecosystem Modelling on High-Performance Computers (M Ashworth et al.); OpenMP in the Physics Portion of the Met Office Model (R W Ford & P M Burton); Converting the Halo-Update Subroutine in the Met Office Unified Model to Co-Array Fortran (P M Burton et al.); Parallel Ice Dynamics in an Operational Baltic Sea Model (T Wilhelmsson); Parallel Coupling of Regional Atmosphere and Ocean Models (S Frickenhaus et al.); Dynamic Load Balancing for Atmospheric Models (G Karagiorgos et al.); HPC in Switzerland: New Developments in Numerical Weather Prediction (M Ballabio et al.); The Role of Advanced Computing in Future Weather Prediction (A E MacDonald); The Scalable Modeling System: A High-Level Alternative to MPI (M Govett et al.); Development of a Next-Generation Regional Weather Research and Forecast Model (J Michalakes et al.); Parallel Numerical Kernels for Climate Models (V Balaji); Using Accurate Arithmetics to Improve Numerical Reproducibility and Stability in Parallel Applications (Y He & C H Q Ding); Parallelization of a GCM Using a Hybrid Approach on the IBM SP2 (S Cocke & Z Christidis); Developments in High Performance Computing at Fleet Numerical Meteorology and Oceanography Center (K D Pollak & R M Clancy); The Computational Performance of the NCEP Seasonal Forecast Model on Fujitsu VPP5000 at ECMWF (H-M H Juang & M Kanamitsu); Panel Experience on Using High Performance Computing in Meteorology OCo Summary of the Discussion (P Prior).

The joint U.S-Canadian project has been devoted to: (a) decadal climate studies using developed state-of-the-art GCMs (General Circulation Models) with enhanced variable and uniform resolution; (b) development and implementation of advanced numerical techniques; (c) research in parallel computing and associated numerical methods; (d) atmospheric chemistry experiments related to climate issues; (e) validation of regional climate modeling strategies for nested- and stretched-grid models. The variable-resolution stretched-grid (SG) GCMs produce accurate and cost-efficient regional climate simulations with mesoscale resolution. The advantage of the stretched grid approach is that it allows us to preserve the high quality of both global and regional circulations while providing consistent interactions between global and regional scales and phenomena. The major accomplishment for the project has been the successful international SGMIP-1 and SGMIP-2 (Stretched-Grid Model Intercomparison Project, phase-1 and phase-2) based on this research developments and activities. The SGMIP provides unique high-resolution regional and global multi-model ensembles beneficial for regional climate modeling and broader modeling community. The U.S SGMIP simulations have been produced using SciDAC ORNL supercomputers. Collaborations with other international participants M. Deque (Meteo-France) and J. McGregor (CSIRO, Australia) and their centers and groups have been beneficial for the strong joint effort, especially for the SGMIP activities. The WMO/WCRP/WGNE endorsed the SGMIP activities in 2004-2008. This project reflects a trend in the modeling and broader communities to move towards regional and sub-regional assessments and applications important for the U.S. and Canadian public, business and policy decision makers, as well as for international collaborations on regional, and especially climate related issues.

In various branches of fluid mechanics, our understanding is inhibited by the presence of turbulence. Although many experimental and theoretical studies have significantly helped to increase our physical understanding, a comp- hensive and predictive theory of turbulent flows has not yet been established. Therefore, the prediction of turbulent flow relies heavily on simulation stra- gies. The development of reliable methods for turbulent flow computation will have a significant impact on a variety of technological advancements. These range from aircraft and car design, to turbomachinery, combustors, and process engineering. Moreover, simulation approaches are important in materials - sign, prediction of biologically relevant flows, and also significantly contribute to the understanding of environmental processes including weather and climate forecasting. The material that is compiled in this book presents a coherent account of contemporary computational approaches for turbulent flows. It aims to p- vide the reader with information about the current state of the art as well as to stimulate directions for future research and development. The book puts part- ular emphasis on computational methods for incompressible and compressible turbulent flows as well as on methods for analysing and quantifying nume- cal errors in turbulent flow computations. In addition, it presents turbulence modelling approaches in the context of large eddy simulation, and unfolds the challenges in the field of simulations for multiphase flows and computational fluid dynamics (CFD) of engineering flows in complex geometries. Apart from reviewing main research developments, new material is also included in many of the chapters.
