Space Weather: The Physics Behind a Slogan K. Scherer, H. Fichtner, B. Heber, U. Mall, Eds. The various processes that connect the physics of the Sun with that of the Earth's environment have become known as "Space Weather" during recent years, a slogan that has emerged in connection with many other expressions adapted from meteorology, such as solar wind, magnetic clouds or polar rain. This volume is intended as a first graduate-level textbook-style account on the physics of these solar-terrestrial relations and their impact on our natural and technological environment.
