Written for the undergraduate, non-majors course, the Third Edition engages students with real-world examples and a captivating narrative. It highlights how we observe the atmosphere and then uses those discoveries to explain atmospheric phenomena. Early chapters discuss the primary atmospheric variables involved in the formation of weather: pressure, temperature, moisture, clouds, and precipitation, and include practical information on weather maps and weather observation. The remainder of the book focuses on weather and climate topics such as the interaction between atmosphere and ocean, severe/extreme weather, and climate change.
