Energy at the Surface of the Earth: An Introduction to the Energetics of Ecosystems presents way of looking at the manner in which the biological, physical, and cultural systems that mantle the landmasses of our planet receive, transform, and give off energy, which is an essential condition of existence that takes many forms. Energy conversions establish the climate in which these systems operate. The principal forms of energy that are converted at the ecosystem scale include radiant, latent, mechanical, chemical and fossil, and thermal. The book begins with radiant energy absorbed by ecosystems—a phenomenon that is independent of their surface temperature and that can be looked on as a burden or a gift, depending on circumstances. An increase in such absorption raises surface temperature, as described in the fulcrum chapter of the book, Chapter VIII. This increase in turn sets into action outflows of energy that by the first law of thermodynamics are equal in energy units, although not necessarily equal in quality to the inflows. The final chapters deal with vertical stratification and areal contrasts in energy budgets, the augmented energy budget of the city, and the responses that serve to keep the budget balanced.
This book focuses on the dynamics of clouds and of precipitating mesoscale meteorological systems. Clouds and precipitating mesoscale systems represent some of the most important and scientifically exciting weather systems in the world. These are the systems that produce torrential rains, severe winds including downburst and tornadoes, hail, thunder and lightning, and major snow storms. Forecasting such storms represents a major challenge since they are too small to be adequately resolved by conventional observing networks and numerical prediction models. Key Features * Key Highlights of This Text * Provides a complete treatment of clouds integrating the analysis of air motions with cloud structure, microphysics, and precipitation mechanics * Describes and explains the basic types of clouds and cloud systems that occur in the atmosphere-fog, stratus, stratocumulus, altocumulus, altostratus, cirrus, thunderstorms, tornadoes, waterspouts, orographically induced clouds, mesoscale convection complexes, hurricanes, fronts, and extratropical cyclones * Presents a photographic guide, presented in the first chapter, linking the examination of each type of cloud with an image to enhance visual retention and understanding * Summarizes the fundamentals, both observational and theoretical, of atmospheric dynamics, thermodynamics, cloud microphysics, and radar meteorology, allowing each type of cloud to be examined in depth * Integrates the latest field observations, numerical model simulations, and theory * Supplies a theoretical treatment suitable for the advanced undergraduate or graduate level
Today's greater public awareness of how climate affects our quality of life and environment has created an increasing demand for climatological information. Now this information is available in one convenient, accessible source, The Encyclopedia of Climatology. This comprehensive volume covers all the main subfields of climatology, supplies data on climates in major continental areas and explains what is known about the causes of climatic processes and changes. Contents include articles on bioclimatology, El Niño, climatic models, world regional climates, civilization and climate, climatic variations and the greenhouse effect.
Summarizes a joint Soviet-American effort to review the role of geographers in global change studies and to suggest how they might contribute to achieving a sustainable development of our planet that will still preserve it as a living system.
The purpose of this extensive annotated bibliography is to assist libraries in the United States, Canada, and other countries to identify, select, and secure publications of value in geography that are appropriate for the purposes and resources of each library collection. More than 2900 entries, published between 1970 and 1984, are arranged by general categories with numerous subdivisions: general aids and sources; history, theory, methodology, and geography; the physical geography; the human geography; applied geography; regional geography; and publications suitable for school libraries. Although publications in other languages have not been excluded, works in English have been emphasized. Basic information provided in each entry includes author, title, place of publication, publisher, publication date, number of pages, identifying numbers, price, Library of Congress card number, and a brief annotation. Where appropriate, translation information including translator and original language are provided. (LH)
