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.

Surveys the horizontal, vertical and temporal discretization techniques for today's and future-generation global atmospheric models. Gives practical guidance in designing dynamical cores: including formulation of the equations, numerical conservation properties, shape-preserving transport, unstructured computational grids and parallel computing aspects. Reviews in depth the many poorly documented dissipation and filtering mechanisms in operational weather prediction and climate models. Includes supplementary material: sn.pub/extras
