This total learning package for the introductory meteorology course includes much more than a text--the book is packaged with the exciting Blue Skies™ CD-ROM and four months' free access to InfoTrac® College Edition, an online university library. At the core of this learning package is Ahrens' respected text, which presents the fundamental concepts of meteorology in the context of everyday weather observations. Fun and easy to understand and relate to, the book and its cumulative organization enables students to build on each concept and gain greater understanding into the dynamic nature of the atmosphere.
