Solar-terrestrial physics deals with phenomena in the region of space between the surface of the Sun and the upper atmosphere of the Earth, a region dominated by matter in a plasma state. This area of physics describes processes that generate the solar wind, the physics of geospace and the Earth's magnetosphere, and the interaction of magnetospheric processes with the upper atmosphere. Such processes are important for energy transfer between the Sun and the terrestrial environment. Many of these processes are mediated by long period wave phenomena, which are usually treated by magnetohydrodynamic methods.Magnetohydrodynamic Waves in Geospace: The Theory of ULF Waves and Their Interaction with Energetic Particles in the Solar-Terrestrial Environment provides the theoretician and experimentalist with a coherent account of the important theoretical ideas that underpin current understanding of ultra-low-frequency wave phenomena in solar-terrestrial physics, and that may be used to address future problems. Brief accounts of observational results are included, as well as appendices describing some key mathematical techniques and magnetic field properties in detailWritten in a concise and clear manner, this book will prove valuable reading for advanced graduate students while active researchers in space plasma physics, solar physics, geophysics, planetary science, and astrophysics in need of a source of detailed information will also appreciate this work.

This book is a study of plasma waves which are observed in the earth''s magnetosphere. The emphasis is on a thorough, but concise, treatment of the necessary theory and the use of this theory to understand the manifold varieties of waves which are observed by ground-based instruments and by satellites. We restrict our treatment to waves with wavelengths short compared with the spatial scales of the background plasma in the mag­ netosphere. By so doing we exclude large scale magnetohydrodynamic phenomena such as ULF pulsations in the Pc2-5 ranges. The field is an active one and we cannot hope to discuss every wave phenomenon ever observed in the magnetosphere! We try instead to give a good treatment of phenomena which are well understood, and which illustrate as many different parts of the theory as possible. It is thus hoped to put the reader in a position to understand the current literature. The treatment is aimed at a beginning graduate student in the field but it is hoped that it will also be of use as a reference to established workers. A knowledge of electromagnetic theory and some elementary plasma physics is assumed. The mathematical background required in­ cludes a knowledge of vector calculus, linear algebra, and Fourier trans­ form theory encountered in standard undergraduate physics curricula. A reasonable acquaintance with the theory of functions of a complex vari­ able including contour integration and the residue theorem is assumed.
