Book Turbulence in the Free Atmosphere

Download or read book Turbulence in the Free Atmosphere written by N. Vinnichenko and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turbulence-the randomly disordered movement of volumes of air of widely varying size-is one of the characteristic features of atmospheric air flows; its investigation is essential for the solution of several theoretical and practical problems. Until recently, owing to experimental difficulties, research on turbu lence was confmed mainly to the lower half of the troposphere. Theoretical investigations have consequently been based on these data. The rapid development of high-altitude aviation and cases of aircraft encoun tering hazardous turbulence led to a sharp intensification of research on turbu lence in the atmosphere up to 10-12 km, and subsequently at greater altitudes. Such research was confined initially to the characterization of the frequency of occurrence of gusts of different speeds, their relation to altitude, geographical conditions, time of day and year, and so on. At the end of the fifties, when the required measuring equipment and experimental techniques had been developed, it became possible to investigate the complete statistical characteristics of turbu lence: the spectral densities of the velocity fluctuations of air flows, structure functions, etc. These data stimulated the further development of theory related to the specific conditions of the free atmosphere.

Book Mean Distributions of Ozone Density Over North America 1963 1964

Download or read book Mean Distributions of Ozone Density Over North America 1963 1964 written by Wayne S. Hering and published by . This book was released on 1965 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: An interim summary of the ozone climate over North America has been prepared from AFCRL ozonesonde network observations made during 1963 and 1964 (AD-435 873, -604 880, -623 018). Mean bimonthly distributions of ozone density computed for individual network stations depict the average ozone structure as a function of altitude and season for the first two years of network operation. Data are also presented on the standard deviation of ozone density and the mean seasonal distributions along a meridional cross section extending from the Canal Zone to Greenland. A brief statistical analysis indicates that approximately 35 to 50 percent of the variance in the total ozone amount at middle and high latitudes is given by the fluctuations in ozone density in the 11- to 13-km or 13- to 15-km layers.

Book A Verification of the Use of the Effective Vertically Integrated Standard Deviation of the Wind in Estimating Dispersion of Vertically Rising Balloons

Download or read book A Verification of the Use of the Effective Vertically Integrated Standard Deviation of the Wind in Estimating Dispersion of Vertically Rising Balloons written by George F. Nolan and published by . This book was released on 1965 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monthly dispersion patterns of vertically rising balloons for various probability levels are computed for the altitude of 90,000 ft by using the effective vertically integrated standard deviation of the wind. These are representative of conditions at the Holloman AFB - White Sands Missile Range complex. The use of this procedure to obtain a reliable measure of dispersion is verified by testing with individually computed ascent trajectories. The importance of considering interlevel correlation coefficients in estimating dispersion is emphasized by the results of this study. The resulting dispersion patterns afford a means of increasing balloon operational efficiency and effectiveness for the cited area by defining the best locations for target flight launchings, and by giving the probable dispersions for flights launched from a fixed site. The findings of this study can also be of assistance in planning balloon operations at other midlatitude locations. (Author).

Book Clear Air Turbulence a Bibliography 1950 1967

Download or read book Clear Air Turbulence a Bibliography 1950 1967 written by Dorothy E. Bulford and published by . This book was released on 1968 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clear air turbulence encounters can occur unexpectedly without any visual evidence or warning. As operations of higher altitude aircraft increase, the phenomenon is encountered more often. Clear air turbulence is defined as 'all turbulence in the free atmosphere of interest in aerospace operations that is not in or adjacent to visible convective activity (this includes turbulence found in cirrus clouds not in or adjacent to visible convective activity).' This bibliography consists of 578 references to technical reports, articles in periodicals, and books published during the past 17 years. References about other forms of turbulence such as that occurring with storms and airplane wake vortices are not included. (Author).

Book Extreme Wind Speeds Gustiness and Variations with Height for MIL STD 210B

Download or read book Extreme Wind Speeds Gustiness and Variations with Height for MIL STD 210B written by Norman Sissenwine and published by . This book was released on 1973 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: MIL-STD-210A, 'Climatic Extremes for Military Equipment', is being revised. The revision will include two sets of windspeed design goals for military equipment being developed for worldwide usage over land: (1) the speed up to which 'operations' are expected to proceed, (2) the speed that equipment should 'withstand' without irreversible damage. A study of gustiness and variations of wind with height during strong wind regimes is presented. Nomograms of gust factor versus gust duration and steady windspeed are used to assign the most dynamically effective gust according to equipment dimensions. Based on a power-law relationship, factors for adjusting windspeed to a common height to describe windspeed and gusts over the vertical extent of military equipment usage are presented. Also included is a tabulation of wind statistics for selected stations considered in the search for worldwide wind extremes.

Book Evaluation of Infrared Emission of Clouds and Ground as Measured by Weather Satellites

Download or read book Evaluation of Infrared Emission of Clouds and Ground as Measured by Weather Satellites written by Clifford Dalton Kern and published by . This book was released on 1965 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of prime interest are the radiation data from that portion of the infrared spectrum known as the atmospheric water-vapor window, ranging from about 8 to 12 microns. Infrared signals received by weather satellites and aircraft depend, in clear air, on surface temperature, atmospheric interference and surface emissivity. For the latter, very different data in literature are found for clouds, water, rocks, etc. In this report correct emissivity data were sought in three ways: (1) Reflectivity of polished rock samples was tested in an infrared spectrograph for 5-16 microns wavelength. Using Kirchhoff's law this method yielded emissivities for near normal incidence. (2) Using an 8-13 microns sensitive radiometer and an aggregate, called emissivity box, the emissivity of many surfaces was measured directly. (3) A summer noon time flight of Tiros over the Mediterranean and the Sahara was evaluated.
