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).

Book Synopsis A Discussion of the Geomagnetic Indices Kp and Ap, 1932 to 1971 by : Allan L. Cage
Download or read book A Discussion of the Geomagnetic Indices Kp and Ap, 1932 to 1971 written by Allan L. Cage and published by . This book was released on 1972 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forty years (1 January 1932 to 31 December 1971) of geomagnetic data in terms of the indices Kp and ap were examined. The frequency distributions of these indices and their semiannual and diurnal variations are tabulated and discussed. Frequency tables were generated based on the present value of the index and the succeeding value of the index. These tables clearly demonstrate the persistent nature of Kp and ap. The use of these data as an aid in geomagnetic forecasting is also discussed. (Author).
Book Synopsis Conditional Probabilities of the Geomagnetic Index Ap by : Philip M. Pazich
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).
Book Synopsis From the Earth's Core to Outer Space by : Ilmari Haapala
Download or read book From the Earth's Core to Outer Space written by Ilmari Haapala and published by Springer Science & Business Media. This book was released on 2012-03-26 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Earth's Core to Outer Space focuses on four themes: (1) Evolving Earth’s crust, (2) Changing Baltic Sea, (3) Climate Change, and (4) Planet Earth, third stone from Sun. The focus on these four topics provides both a state of the art review of earth science topics of particular importance to Scandinavia and the Baltic and also the global context in which a consideration of these topics must be made. It finishes by discussing our use of space born technologies for understanding these topics and places the Earth within the context of our neighbouring planets and their satellites. The first theme includes papers on the structure, origin and evolution of the Earth’s crust and in particular the ore deposits in Fennoscandia, plate-tectonic drift of Fennoscandia (Baltica), and postglacial isostatic rebound of the crust. The second theme contains papers dealing with changes in the ice season of the Baltic Sea, inflow and stagnation in deep basins, biology of the Baltic Sea, and carbon dioxide balance in sea water. The third theme deals with origin and evolution of oxygen in atmosphere, postglacial climate change, effects of aerosols and greenhouse gases on climate, interplay between anthropogenic and natural factors in the current climate change, and Earth’s water resources. The fourth theme includes articles on Earth’s space environment, use of satellites in cartography and geodesy, information obtained by space probes on Mars and other planets and their moons, and possibilities to find life on them.

Book Synopsis Recalibration of Bartels' Geomagnetic Activity Indices Kp and Ap to Include Universal Time Variations by : Leif Svalgaard
Download or read book Recalibration of Bartels' Geomagnetic Activity Indices Kp and Ap to Include Universal Time Variations written by Leif Svalgaard and published by . This book was released on 1975 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ap index (and derived indices) can be recalibrated using Mayuad's am-index to recover the correct Universal Time variations. Such variations were artificially removed in the original ap-index. A number of tests are performed to show that the correct index is capable of revealing the desired variations. These tests include comparisons of the UT-variations on days of opposite interplanetary magnetic sector polarity. A finding, that geomagnetic activity was considerably higher during intervals of Toward polarity prior to 1963, is strongly confirmed.

Book Synopsis Literature 1972, Part 2 by : S. Böhme
Download or read book Literature 1972, Part 2 written by S. Böhme and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is de voted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, com pared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume 8 contains literature published in 1972 and received before March 15, 1973; some older liter ature which was received late and which is not recorded in earlier volumes is also included.
