'… provides a very nice deductive derivation of the planetary geostrophic equations using scaling analysis, and is one of the most rigorous treatments that this reviewer has seen … There is also a nice selection of exercises at the end of the book relating to each chapter, varying in degree of difficulty. Speaking as an educator, this is a useful and welcome resource for those who plan on using this book as a class text … I would recommend this book to anyone who wishes to gain an understanding of some of the fundamental ideas that underpin our current thinking about the dynamics that govern the large-scale circulation. I would also recommend it as a graduate-level text for a dynamics-based physical oceanography class.' Andrew M. Moore, Bulletin of the American Meteorological Society
