From The Publisher:
     This scholarly text provides an introduction to the numerical methods used to model partial differential equations governing wave-like and weakly dissipative flows. The focus of the book is on fundamental methods and standard fluid dynamical problems such as tracer transport, the shallow-water equations, and the Euler equations. The emphasis is on methods appropriate for applications in atmospheric and oceanic science, but these same methods are also well suited for the simulation of wave-like flows in many other scientific and engineering disciplines. Numerical Methods for Wave Equations in Geophysical Fluid Dynamics will be useful as a senior undergraduate and graduate text, and as a reference for those teaching or using numerical methods, particularly for those concentrating on fluid dynamics.

 From Acta Meteorologica Sinica - Ding Yihu, Zhao Nan, and Zhou Jiangxing: excellent reference in computational fluid dynamics, and numerical methods in applied partial differential equations. This book should be brought to the attention of readers in meteorology, oceanography, physics, mechanics and engineering. It is an excellent textbook. This book gives extensive and deep discussions of the main theoretical and practical research results in numerical geophysical fluid dynamics. Compared with other books in this field, the extensiveness, theoretical and practical deepness this book reaches makes it a classical work.
