Download or read book Conditional Probabilities of the Geomagnetic Index Ap written by Philip M. Pazich and published by . This book was released on 1976 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data of the geomagnetic index A sub p from 1932 to 1973 were used to determine the conditional probabilities for the occurrence of certain values of that index. The range of values was divided into three categories that approximately correspond to quiet, moderate, and disturbed levels of geomagnetic activity. Conditions applied were the category level of activity on the initial and subsequent day and the portion of the solar sunspot cycle. Conditional probabilities were determined for 100 successive days after the initial day, both for the quiet and active portions of the sunspot cycle. (Author).

This book was released on 1971 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ionospheric propagation of high-frequency radio waves is profoundly influenced by the variations of sunspot numbers and of geomagnetic activity. Thus, details of these variations, and of the relationship between them, has practical application. The variation of the geomagnetic activity index Ap over the 38-year interval January, 1932 through January, 1970 differs in several important characteristics from the variation of sunspot numbers over the same interval. A spectral analysis approach was used d to investigate this variation of AP, as well as its relation to the variation of sunspot numbers. The data analyzedconsisted of the 457 monthly average AP indices (AP) for the interval and the corresponding observed monthly sunspot numbers. Several large samples of the original daily Ap indices were also analyzed. Two of the latter samples covered 11-year intervals (April 1, 1944 - June 2, 1955; and June 1, 1956 - July 31, 1967) and the third covered a 23-year interval (April 1, 1944 - December, 1967).

Available in PDF, EPUB and Kindle. Book excerpt: Data concerning the spatial and temporal inhomogenities of atmospheric density and composition and their implication concerning the atmospheric infrared radiance are reviewed. Preliminary estimates of the variability in the radiance are presented. In addition, the range of scale sizes from small-scale variations is also considered.

Download or read book Hydro Environmental Analysis written by James L. Martin and published by CRC Press. This book was released on 2013-12-04 with total page 5742 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing on fundamental principles, Hydro-Environmental Analysis: Freshwater Environments presents in-depth information about freshwater environments and how they are influenced by regulation. It provides a holistic approach, exploring the factors that impact water quality and quantity, and the regulations, policy and management methods that are necessary to maintain this vital resource. It offers a historical viewpoint as well as an overview and foundation of the physical, chemical, and biological characteristics affecting the management of freshwater environments. The book concentrates on broad and general concepts, providing an interdisciplinary foundation. The author covers the methods of measurement and classification; chemical, physical, and biological characteristics; indicators of ecological health; and management and restoration. He also considers common indicators of environmental health; characteristics and operations of regulatory control structures; applicable laws and regulations; and restoration methods. The text delves into rivers and streams in the first half and lakes and reservoirs in the second half. Each section centers on the characteristics of those systems and methods of classification, and then moves on to discuss the physical, chemical, and biological characteristics of each. In the section on lakes and reservoirs, it examines the characteristics and operations of regulatory structures, and presents the methods commonly used to assess the environmental health or integrity of these water bodies. It also introduces considerations for restoration, and presents two unique aquatic environments: wetlands and reservoir tailwaters. Written from an engineering perspective, the book is an ideal introduction to the aquatic and limnological sciences for students of environmental science, as well as students of environmental engineering. It also serves as a reference for engineers and scientists involved in the management, regulation, or restoration of freshwater environments.
