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.


Seamless Prediction of the Earth System: from Minutes to Months

Cote, J., C. Jablonowski, P. Bauer and N. Wedi (2015), Numerical Methods of the Atmosphere and Ocean, in: Brunet, G., S Jones and P. M. Ruti (Eds.), Seamless Prediction of the Earth System: from Minutes to Months, World Meteorological Organization (WMO) No. 1156, Geneva. pp. 101-124

We are entering a new era in technological innovation and in use and integration of different sources of information for improving well-being and the ability to cope with multi-hazards. New predictive tools able to detail weather conditions to neighbourhood level, to provide early warnings a month ahead, and to forecast weather-related impacts such as flooding and energy consumption will be the main outcomes of the next ten years research activities in weather science. A better understanding of small-scale processes and their inherent predictability should go together with a better comprehension of how weather- related information influences decisional processes and with better strategies for communicating this information. Within this perspective, this book is intended to be a valuable resource for anyone dealing with environmental prediction matters, providing new perspectives for planning and guiding future research programmes.

  • The figure shows snapshots of the day-10 wind speed of an idealized tropical cyclone from the four dynamical cores FV, HOMME, EUL and SLD that are part of the NCAR Community Earth System Model CESM1. The resolutions are approximately 28 km (0.25 degrees) and 38 km (T340) with 26 vertical levels. An aqua-planet configuration with the CAM4 physics package is used.

  • The figure shows snapshots of various test cases computed with the nonhydrostatic high-order finite-volume dynamical core described in Ullrich and Jablonowski (Mon. Wea. Rev. 2012). The large-scale example (top) depicts a breaking baroclinic wave in a periodic channel on an f-plane, the meso-scale example displays linear gravity waves triggered by a small mountain (not shown), and the micro-scale example shows a rising thermal bubble that mimics convection.
