This book was released on 1960 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: The joint tower-airplane experiment was designed to provide concurrent turbulence data for one flight level (at or near tower height) and at the same time to supplement these data with airplane measurements above, and tower measurements below, the tower height. Three tower locations were incorporated in this experiment in an attempt to determine the effects of diffn be simply related to turbulence measured at a fixed point as a function of time, (2) Obtain data for examining low level temporal and spatial homogeneity, (3) Investigate the influence of terrain variations on the turbulence power spectral densitrent topographical conditions on the turbulence spectrum. The 4 principal objectives were: (1) Obtain data to test the hypothesis of G.I. Taylor (1937) that turbulence encountered along a path in space aligned with the mean wind can be simply related to turbulence measured at a fixed point as a function of time, (2) Obtain data for examining low level temporal and spatial homogeneity, (3) Investigate the influence of terrain variations on the turbulence power spectral densities, and (4) Investigate the variation of turbulence characteristics with height above ground.

This book was released on 1959 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memorandum presents results of a limited literature survey showing the atmosphere is typically in a turbulent state and contains vertical motions due to eddies having a wide range of size and intensity. The methods of power spectral analysis and their applications to atmospheric turbulence studies are outlined, and references provided, for possible use in implementing needed programs at test ranges and in development projects. These programs should include comprehensive studies of the environmental turbulence at test ranges, which should themselves be regarded as instruments possessing inherent physical characteristics which influence the tests being made.

Book excerpt: The objects of the American Meteorological Society are "the development and dissemination of knowledge of meteorology in all its phases and applications, and the advancement of its professional ideals." The organization of the Society took place in affiliation with the American Association for the Advancement of Science at Saint Louis, Missouri, December 29, 1919, and its incorporation, at Washington, D. C., January 21, 1920. The work of the Society is carried on by the Bulletin, the Journal, and Meteorological Monographs, by papers and discussions at meetings of the Society, through the offices of the Secretary and the Executive Secretary, and by correspondence. All of the Americas are represented in the membership of the Society as well as many foreign countries.

This book was released on 1956 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method for obtaining a power spectrum of gust vertical velocity over a wide range of wavelength from simultaneous measurements made in flight has been devised and applied. This method has the advantage of not involvhg the use of airplane transfer functions. A gust vertical velocity spectrum was determined for one meteorological condition for wavelengths from 10 feet to 60,000 feet. The test was conducted at low altitude in clear- turbulence having a root-mean-square intensity of 5 feet per second. At the higher frequencies (shorterwavelengths), the power spectral density varied at a rate which was between the -5/3 power which has been predicted theoretically and the inverse square of the frequency. The spectrum which was obtained tended to flatten out for the longest test wavelengths.The break frequency which provides an indication of the scale of the turbulence occurred at a wavelength of approximately 6,000 feet. The results obtained indicate that the method of obtaining spectra used in this investigation is practicable.
