The new edition of this text addresses the needs of professors to quantify the concepts in Ahrens by providing the mathematical equations needed for a more detailed understanding of weather. The organization maps directly to Ahrens, making Stull the perfect companion. It is not a lab manual nor a workbook, but it does contain numerous solved problems which students can solve. The text demonstrates how to use equations by including numerous solved examples that demonstrate with mathematics (algebra, geometry, trigonometry and finite differential equations but not calculus) the dominant characteristics of certain atmospheric phenomena and processes.
