Available in PDF, EPUB and Kindle. Book excerpt: Detection of radar echoes from the optically clear atmosphere in the early 1950's led to vigorous debate within the weather radar community as to their origins. Members of this program later used the radars at Wallops Island, Va., to observe the clear atmosphere, detecting the tropopause by radar in 1966 and confirming that most of the clear air echoes were due to turbulence. Research through the 1950's and 1960's led to improved understanding of stratiform rain systems, hurricanes, and severe convective storms. The first rain parameter diagram was developed in 1957. Doppler radar was used in 1961 to produce the first wind profile from radar measurements and in 1968 to make the first radar observation of a mesocyclone. The research on severe storm dynamics, both at the Air Force radar site in Sudbury, Mass., and in collaboration with the National Severe Storms Laboratory in Oklahoma, laid much of the foundation for the Next Generation Weather Radar (NEXRAD) program. Field work at Wallops Island and at Kwajalein Atoll in the 1970's in support of Air Force reentry vehicle test programs included the first display of analysis products generated from radar data by a computer in real time. In recent years much effort has been devoted to the development of data analysis algorithms for NEXRAD. Other current work includes measurement of wind profiles by UHF Doppler radar and the development of polarization diversity techniques for documenting hydrometer microphysical parameters and processes.

Available in PDF, EPUB and Kindle. Book excerpt: The frequency and probability of radar echoes of convective clouds over the United States are presented. Analysis of three years of observations from a 31-station WSR-57 weather radar network indicates that at all altitudes, radar echo probabilities are greatest over Florida and the Gulf coast, generally decreasing northward over the United States. Also, largest probabilities for most layers and locations occur in summer. Echoes have been reported up to at least 70 kft in May, June, and July, and up to 60 kft in winter. Diurnal variations reveal greatest probabilities between 1600 and 2100 LST in all regions. Largest mean monthly 3-hour values are 85 percent, and the maximum mean daily range is roughly 65 percent in the southeast during the summer months. The probability of an echo-free horizontal view near the earth's surface for a 100-mile range is also presented. Tabulations of echo-free sectors, as percent of the 360-degree radar scope, show that the probability of obstructions to a horizontal view increases generally from northwest to southwest during all seasons. The probability of having no echoes is greater in winter than in summer except along the Pacific coastal region. Diurnal variability is larger in July than in January. (Author)

This book was released on 1989 with total page 1298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.

Available in PDF, EPUB and Kindle. Book excerpt: A review is made of the assumptions that must be made in using a weather radar set for quantitative measurements of weather echoes. A simplified derivation is provided showing the relationship between the purely meteorological 'radar reflectivity factor' Z and the radar received power for any weather radar set when the assumptions are fulfilled. A nomogram furnished for use with the AN/FPS-77 enables a simple conversion of receiver power to Z values. (Author).
