This book was released on 1961 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This bibliography constitutes the second in a series of four or five being prepared by Meteorological Abstracts for the Boulder Laboratories of the National bureau of Standards. The general subject area of these compilations in propagation of electromagnetic (radio) waves in the atmosphere. The present bibliography consists of 368 abstracts on meteor trail propagation, arranged alphabetically by author and including articles dating from the earliest studies by Nagaoka (B-245) in 1929 on the effect of meteoric ionization on radio communications, to the numerous papers reflecting the recent emphasis on meteor burst communication. No material published after 1960 has been included.

Available in PDF, EPUB and Kindle. Book excerpt: The possibility of detecting communication systems which use signals scattered by meteor trails, and intercepting information passed over such systems is discussed. To obtain the statistical data required on the fraction of meteor trails that scatter energy to an intercept location, and the fraction of transmitted messages that can be intercepted, a computation program is formulated. For a specified distribution of meteor sources, the fraction of the meteor trails that will scatter a signal to any point in a large area about the transmitter, and the fraction of message fragments received that can be intercepted at any point in the region about a receiver location, can be readily found. The computed results for a uniform distribution of meteor sources across the sky are displayed graphically. An example is worked out showing that the data can be used to estimate the performance of a meteor-scatter communications link. Sample computations on the probability of detecting the operation of a meteor-burst communications system are carried out. Finding the locations of transmitters using meteor-scatter signals, recognition of operating characteristics, and the interception of information passed over such links are also discussed. (Author).

Book excerpt: 45 downwards because (j on the average increases with height; but this conclusion does not follow from (18.3) when the dependency of Kc upon ~o is taken into consideration. s 2 ERTELl and PRIESTLEY and SWINBANK have shown that the upward eddy flux of sensible heat must be larger than indicated by (18.3), because this formula does not account for the fact that rising eddies are systematically warmer than sinking eddies because of the effect of buoyancy. The reader is referred to the reviews by SUTTON [22], [23] and PRIESTLEY and SHEP PARD [15) for further details concerning eddy-flux of heat and turbulent diffusion. 19. RICHARDSON'S criterion.
