Book Description
This report documents the ten-year (1981-91) development of the Phillips Laboratory Global Spectral Model (PL GSM). Beginning with the National Meteorological Center Model of 1980, the hydrodynamics of the model were recoded and new physical parameterizations were developed for radiation, planetary boundary layer, cumulus convection, and gravity wave drag effects on the large- scale forecast fields. A sequence of tests and parameterization refinements were carried out to arrive ultimately at the current version of the PL GSM, termed PL-91. The report describes its performance with respect to that of the operational AFGWC GSM in a series of six January and June forecasts. The PL-91 version appears to produce better forecasts of virtually all parameters, producing small systematic errors and slower error growth. The model is envisioned to serve as a research tool to develop techniques for global cloud forecasting.

Spectral Numerical Weather Prediction Models
Author: Martin Ehrendorfer
Publisher: SIAM
ISBN: 1611971993
Category : Mathematics
Languages : en
Pages : 503
Book Description
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.
