Download or read book Monthly Midlatitude Atmospheres Surface to 90 Km written by Arthur J. Kantor and published by . This book was released on 1976 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sets of mean monthly Reference Atmospheres that reflect the seasonal changes in the vertical distributions of temperature, pressure, and density at altitudes up to 90 km are presented for latitudes 30 deg N and 45 deg N. Estimates of the magnitude of the diurnal, day-to-day, and spatial variability of temperature and density are included for altitudes above 20 km. Special attention is given to the distribution of atmospheric density since density is the atmospheric property of most concern to aerospace designers and engineers. This report is part of a comprehensive effort to develop sets of mean monthly atmospheric models, surface to 90 km, for 15 deg intervals of latitude from pole to equator. The research is being performed to help satisfy the many requests that have been received from Air Force engineers and designers for information on the time and space variability of atmospheric density and temperature at altitude up to 90 km.

Book excerpt: A set of 12 mean monthly reference atmospheres, which describes the seasonal changes in the distribution of the thermodynamic properties of the atmosphere, is provided for the North Pole for altitudes up to 55 km. Additional atmospheric models for arctic and subarctic regions are presented to describe the large variations that occur in the vertical distributions of atmospheric temperature, density, and pressure during typical warmings and coolings of the winter stratosphere and mesosphere.

Book excerpt: Sets of mean monthly reference atmospheres that describe seasonal changes in the vertical distributions of temperature, density, and pressure up to 90 km are presented for 15 intervals of latitude between the equator and pole. Specialized atmospheres are included that portray longitudinal variations in monthly median values of temperature, density, and pressure during winter months. Other models illustrate the magnitude of the changes in the vertical distributions of these atmospheric properties during winter warmings and coolings of the stratosphere and mesosphere in arctic and subarctic regions. Estimates of the day-to-day variations around the monthly median values of temperature and density are provided for each set of models. (Author).

Download or read book Variability of Atmospheric Density in the Middle Atmosphere written by Arthur J. Kantor and published by . This book was released on 1983 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of the time and space variability of density in the middle atmosphere has been developed in this report, affording a means to determine density changes that occur over distances out to 200 nmi and time periods of 1 to 72 hr. Spatial variations - The rms differences between densities at locations 50, 100, and 200 nmi apart are provided in Tables 4, 8 and 11 for low- and middle- latitude stations at altitudes from 20 through 60 km. These rms values are estimates of the day-to-day variability around the mean density gradients given in Table 5 for low latitudes and Tables 9 and 12 for middle latitudes. Time variations - The rms variability of density for time periods from 1 to 12 hr in tropical regions is given in Table 13 for altitudes up to 60 km. Estimates were derived using autocorrelation theory and an analysis of the diurnal variation of density, which is the dominant periodic cycle at low latitudes. Analyses of available density observations at several midlatitude locations for altitudes between 30 and 60 km provide reasonable estimates of the magnitude (and changes with season and latitude) of the variability of density with time for periods up to 72 hr. Variations of density at these latitudes are relatively small during summer and do not increase significantly with time. Rms variations remain between 1-1/2 and 4 percent for all periods up to 72 hr.

Download or read book Helicography written by Craig Dworkin and published by punctum books. This book was released on 2021-07-18 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part art history essay, part experimental fiction, part theoretical manifesto on the politics of equivalence, Helicography examines questions of scale in relation to Robert Smithson's iconic 1970 artwork Spiral Jetty. In an essay and film made to accompany the earthwork, Smithson invites us to imagine the stone helix of his structure at various orders of magnitude, from microscopic molecules to entire galaxies. Taking up this invitation with an unrelenting and literal enthusiasm, Helicography pursues the implications of such transformations all the way to the limits of logic. If other spirals, from the natural to the man-made, were expanded or condensed to the size of Spiral Jetty, what are the consequences of their physical metamorphoses? What other equivalences follow in turn, and where do their surprising historical, cultural, and mechanical connections lead? This book considers a number of forms in order to find out: the fluid vortices of whirlpools, hurricanes, and galaxies; the delicate shells of snails and the threatening pose of rattlesnakes; prehistoric ferns and the turns of the inner ear; the monstrous jaws of ancient sharks; a baroque finial scroll on a bass viol; a 19th-century watch spring; phonograph discs and spooled film; the largest open-pit mine on the planet. The result is a narrative laboratory for the "science of imaginary solutions" proposed by Alfred Jarry (whose King Ubu also plays a central role in the story told here), a work of fictocriticism blurring form and content, and the story of a single instant in time lost in the deserts of the intermountain west. Craig Dworkin is the author of four scholarly monographs - Reading the Illegible (Northwestern University Press), No Medium (MIT Press), Dictionary Poetics: Toward a Radical Lexicography (Fordham University Press), and Radium of the Word: a Poetics of Materiality (Chicago University Press) - as well as a half-dozen edited collections and a dozen books of experimental writing, including, most recently, The Pine-Woods Notebook (Kenning Editions). He teaches literary history and theory at the University of Utah.

Download or read book New Weather Sensing and Forecasting Capabilities for Ground to Space Operations written by Charles Schutz and published by . This book was released on 1987 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Certain weather variables exercise an important control over space operations, either by making a launch infeasible or by adversely affecting the space vehicle and its trajectory. Climatological studies and standard National Weather Service observations show that the normal range of variability with location and season, even from day to day, precludes the forecasting of these variables sufficiently accurately for precise trajectory control. Several new systems are now becoming available for measuring wind and density (or variables from which density can be computed) continuously and automatically: VAS, PROFILER, WINDSAT, and the nest generation of weather satellites. Together these systems offer the promise of continuous real-time monitoring of winds and air density throughout that part of the atmosphere that exercises the greatest influence on space operations.
