This revision retains the hallmarks professors have come to expect from Tarbuck and Lutgens: a friendly, largely non-technical narrative, timely coverage of recent atmospheric events, and carefully crafted artwork by leading science illustrator Dennis Tasa. The Twelfth Edition maintains a student-friendly approach while evolving to address various course challenges and trends. New digital visualization and assessment tools are now available on MyMeteorologyLab, a new resource that both encourages student self-study and enables instructors to manage their courses online, with customizable assessments for students. Each chapter in this revision is organized by a new active learning path to help guide and engage non-science majors. A greater focus on popular and increasingly important Severe & Hazardous Weather applications, new critical visual analysis Eye on the Atmosphere features, as well as new discussions of the real-world career opportunities of meteorology with Professional Profile essays, make the science both relevant and exciting.
