About This Book

The text presents an accessible introduction to meteorology, tracing how atmospheres form and behave and explaining light, heat, temperature, and condensation. It surveys observational tools and techniques, including instrument shelters, kites, and weather maps, and teaches how to read daily synoptic charts to recognize and forecast cyclones, cold waves, tornadoes, and frost. It discusses global wind and pressure patterns, climate and its modification by land, ocean, and human activity, regional climatic suitability for health and agriculture, and the organization and history of the national weather service, aiming to make practical weather knowledge usable by lay readers and students.
