Fluid Mechanics of the Atmosphere presents the fundamental equations which govern most of the flow problems studied by atmospheric scientists. The equations are derived in a systematic way that is intended to facilitate critical evaluation. The goal of this text is twofold. First, the book supplies the student a background familiarity in the underlying physics behind the mathematics. Second, it explores some systematic methods of relating these physics to atmospheric problems, including rotating frames of reference effects, vorticity dynamics, and turbulence effects on closure. It stresses vorticity, principles of scaling, and turbulence. It is extensively illustrated. It includes end-of-chapter summaries and problem sets. It is been classroom tested for five years.
