The prime motivation that has led to the writing of this book has been my desire to present in a single place all the details that need to be attended to when an NWP model is constructed. These details are covered in the book by constructing a specific spectral model named PEAK. Such a comprehensive and detailed presentation does not - so far and to the best of my knowledge - exist in the available NWP literature.
Of course, detailed technical documentation is, sometimes electronically, available for most, if not all, NWP models that are in use. In view of the degree of complexity of such presently-used models, however, sometimes these documentations are very complex themselves, difficult to access without prior NWP modeling experience, and frequently do not directly link to the coded structure of the model.
In an attempt to provide an accessible and complete model description starting with the formulation of the continuous model equations and ending with the coded model, this book describes spectral NWP models, in general, as well as the newly-created spectral NWP model PEAK, in particular.
The book contains in printed form the entire Fortran 90/95 code of PEAK available electronically on the code page, in addition to a succint flow diagram and description of tasks carried out by individual subroutines. The book contains in its first part a presentation of theoretical fundamentals of atmospheric dynamics that serve as the stepping stone for building a numerical model describing atmospheric flows.
