This first chapter is an introduction that provides all the basic information that the reader will need for a profitable use of the book. It reviews the vertical structure of the atmosphere, the surface-energy budget and concepts of atmospheric stability. The atmosphere is conventionally divided into layers based on the vertical structure of density, pressure and temperature fields. This is an important issue in understanding the dynamics of the middle atmospheric and variations of the main meteorological parameters.
