Microphysics of Atmospheric Phenomena
Author: Boris M. Smirnov
Publisher: Springer
ISBN: 3319308130
Category : Science
Languages : en
Pages : 269
Book Description
This book investigates elementary processes in the Earth’s atmosphere involving photons, electrons, ions, radicals, and aerosols. It is based on global atmospheric models such as the standard atmospheric model with averaged atmospheric parameters across the globe and over time, the Earth’s energetic balance, and the global electric circuit that allows to analyze fundamental atmospheric properties to be analyzed. Rate constants of elementary processes in the Earth’s atmosphere, together with measured atmospheric parameters and existing concepts of atmospheric phenomena, are used in the analysis of global and local atmospheric processes. Atmospheric photoprocesses result from the interaction of solar radiation with the atmosphere and processes involving ions, oxygen atoms, excited atomic particles and ozone molecules. Atmospheric electricity as a secondary phenomenon to atmospheric water circulation results in a chain of processes that begins with collisions of water aerosols in different aggregate states. Cosmic rays are of importance for atmospheric electricity, as they create positive and negative ions in the air. Air breakdown in an electric field of clouds in the form of lightning may develop under the influence of cosmic ray-created seed electrons, which are necessary for electron multiplication in ionization wave-streamers. The upper atmosphere (ionosphere) is formed under solar radiation in a vacuum ultraviolet spectrum, and absorption of this radiation leads to air photoionization. The greenhouse effect is determined by atmospheric water, whereas transitions between a water vapor and aerosols may lead to a change in atmospheric optical depth. Carbon dioxide contributes in small portions to the atmospheric greenhouse effect. Cosmic rays are of importance for atmospheric discharge, the origin of lightning and cloud formation in the first stage of aerosol growth. This book provides a qualitative description of atmospheric properties and phenomena based on elementary processes and simple models.

The Geography of South Africa
Author: Jasper Knight
Publisher: Springer
ISBN: 3319949748
Category : Science
Languages : en
Pages : 317
Book Description
This edited collection examines contemporary directions in geographical research on South Africa. It encompasses a cross section of selected themes of critical importance not only to the discipline of Geography in South Africa, but also of relevance to other areas of the Global South. All chapters are original contributions, providing a state of the art research baseline on key themes in physical, human and environmental geography, and in understanding the changing geographical landscapes of modern South Africa. These contributions set the scene for an understanding of the relationships between modern South Africa and the wider contemporary world, including issues of sustainable development and growth in the Global South.

The Weather and Climate of Southern Africa
Author: P. D. Tyson
Publisher: Oxford University Press, USA
ISBN:
Category : Nature
Languages : en
Pages : 420
Book Description
The Weather and Climate of Southern Africa, the second edition of The Atmosphere and Weather of Southern Africa, further consolidates and expands Tyson and Preston-Whyte's in-depth textbook on the meteorology of southern Africa. It offers an introduction to the structure of the atmosphere, and detailed, well-illustrated discussions on the physics of meteorology, measurement, weather systems, ocean-atmosphere interactions, pollution, climactic change, and forecasting. With a new emphasis on the growing field of climatology, this book is especially pertinent to environmental studies in and on the developing countries of southern Africa, and the relationship of the subcontinent to global weather and climatic changes.
