This enlightening, entertaining, and well-illustrated text for anyone curious about nature features numerous diagrams and full-page illustrations. Topics include the atmosphere, climatology, storms, historical weather studies, and weather lore.

Fascinating, authoritative, easy-to-follow guide to flower form and function, orchids, Eastern and Western wildflowers, older cultivated varieties, today’s perennials, annuals and biennials; flowering trees and shrubs, and tropical and subtropical flowers. Includes botanical and common names, places of origin, outstanding characteristics, and practical advice on planting and cultivation.

This highly readable and informative guide answers hundreds of fascinating questions about storms and atmospheric phenomena. In addition to dispelling common misconceptions, it imparts a wealth of solid scientific data about hurricanes, tornadoes, thunderstorms, wind, fog, ice storms, and other events. The text is embellished with 72 drawings and 20 photographs.

Takes the reader on a voyage of discovery as the author traces a single mass of air traveling from the Canadian Rockies to the northeastern United States.

"Mark Wilson presents a highly original and broad-ranging investigation of the way we get to grips with the world conceptually, and the way that philosophical problems commonly arise from this. He combines traditional philosophical concerns about human conceptual thinking with illuminating data derived from a large variety of fields including physics and applied mathematics, cognitive psychology, and linguistics. Wandering Significance offers abundant new insights and perspectives for philosophers of language, mind, and science, and will also reward the interest of psychologists, linguists, and anyone curious about the mysterious ways in which useful language obtains its practical applicability."--Publisher's description.

This excellent text is a pioneering work in the study of landform development under processes associated with running water. Its primary emphasis is on subjects that were the focus of the authors' studies in both field and laboratory. Part I deals with the process of change in the evolving landscape. Part II explores process and form, and Part III, the effects of time. In Part I, the relation of geomorphology to field problems is analyzed in studies of a mountain block in a semiarid climate, a meandering river cut into bedrock, and benches along a sea coast. Part Two contains studies of weathering, climate, and such denudational processes as flooding and erosion. Here, too, are examinations of the drainage basin as a geomorphic unit, water and sediment in channels, channel form and process, and hillslope characteristics and processes. In Part III, the authors cover geochronology, drainage pattern evolution, channel changes with time, and the evolution of hillslopes. Two appendixes will help readers convert units and equivalents, and identify symbols and nomenclature. 1964 edition.

This book reviews the principles of Doppler radar and emphasizes the quantitative measurement of meteorological parameters. It illustrates the relation of Doppler radar data and images to atmospheric phenomena such as tornadoes, microbursts, waves, turbulence, density currents, hurricanes, and lightning. Geared toward upper-level undergraduates and graduate students, this text was written by two scientists at the National Severe Storms Laboratory in Norman, Oklahoma, a division of the National Oceanic and Atmospheric Administration. Topics include electromagnetic waves and propagation, weather signals and their Doppler spectra, weather signal processing, measurements of precipitation and turbulence, and observations of winds and storms as well as fair weather. Radar images and photographs of weather phenomena highlight the text.
