Download or read book Weather Radar Technology Beyond NEXRAD written by National Research Council and published by National Academies Press. This book was released on 2002-08-31 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weather radar is a vital instrument for observing the atmosphere to help provide weather forecasts and issue weather warnings to the public. The current Next Generation Weather Radar (NEXRAD) system provides Doppler radar coverage to most regions of the United States (NRC, 1995). This network was designed in the mid 1980s and deployed in the 1990s as part of the National Weather Service (NWS) modernization (NRC, 1999). Since the initial design phase of the NEXRAD program, considerable advances have been made in radar technologies and in the use of weather radar for monitoring and prediction. The development of new technologies provides the motivation for appraising the status of the current weather radar system and identifying the most promising approaches for the development of its eventual replacement. The charge to the committee was to determine the state of knowledge regarding ground-based weather surveillance radar technology and identify the most promising approaches for the design of the replacement for the present Doppler Weather Radar. This report presents a first look at potential approaches for future upgrades to or replacements of the current weather radar system. The need, and schedule, for replacing the current system has not been established, but the committee used the briefings and deliberations to assess how the current system satisfies the current and emerging needs of the operational and research communities and identified potential system upgrades for providing improved weather forecasts and warnings. The time scale for any total replacement of the system (20- to 30-year time horizon) precluded detailed investigation of the designs and cost structures associated with any new weather radar system. The committee instead noted technologies that could provide improvements over the capabilities of the evolving NEXRAD system and recommends more detailed investigation and evaluation of several of these technologies. In the course of its deliberations, the committee developed a sense that the processes by which the eventual replacement radar system is developed and deployed could be as significant as the specific technologies adopted. Consequently, some of the committee's recommendations deal with such procedural issues.
Download or read book Tornado Identification from Analyses of Digital Radar Data written by Donald Wayne Pittman and published by . This book was released on 1976 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted to determine whether tornadoes presented a unique signature in analyses of digital radar data from central Oklahoma during the Spring. The data were collected by the 10-cm-WSR-57 radar at the National Severe Storms Laboratory at Norman, Oklahoma. Three types of numerical analyses were used in this study: constant-altitude reflectivity maps (CAZM), total vertically-summed reflectivity maps (TVSZ), and partial vertically-summed reflectivity maps (PVSZ), with greatest emphasis placed on the PVSZ maps. Presentations covering a 100-km square were constructed at either 5 to 10 min intervals. From the analysis of three case studies during during 1974 and 1975, that contained five tornadoes, it was concluded that tornadoes did not produce a singular identifying signature in analyses of digital radar data, but rather produced a combination of features which indicated, with a high probability, the presnce of a tornado. Such features were the appearance of a small area of reduced reflectivity known as a Bounded Weak-Echo Region (BWER), a tilt of the core of the storm toward the BWER, and a rapid decrease in the upper-level mass of the storm as indicated by a rapid decrease in the reflectivity of the upper PVSZ.
Download or read book Operational Benefits of Meteorological Doppler Radar written by Ralph J. Donaldson and published by . This book was released on 1975 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comparison is made between Doppler and conventional radar as a tool in operational forecasting of hazardous weather. Estimates are given of the cost increment of Doppler capability above the basic radar cost. The advantages and limitations of dual-Doppler and multi-Doppler networks are also considered. The evidence leads to the firm conclusion that, for operations in areas subject to the threat of tornadoes, hurricanes, and other damaging windstorms, the cost increment of single-Doppler radar capability is more than justified by its advantages over conventional radar. On the other hand, dual-Doppler capability is not recommended for operational use, although it is an excellent research tool.

Download or read book Doppler Radar Investigation of Flow Patterns Within Severe Thunderstorms written by Michael J. Kraus and published by . This book was released on 1973 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four severe thunderstorms were observed on a single day by the AFCRL 5.4-cm Doppler radar at Sudbury, Massachusetts. Quasihorizontal radial velocity information was used to construct maps depicting the mean within-storm flow at different elevation angles over a period of about 20 minutes. Well organized patterns in the velocity field showed either persistence or slow evolution in time throughout an appreciable range of height. The merits of this single Doppler method for the investigation of future outbreaks are discussed. (Author).

Download or read book Joint Agency Doppler Technology Tests written by Ralph J. Donaldson and published by . This book was released on 1980 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Joint Doppler Operational Project was a cooperative inter-agency program directed toward the evaluation of recent advances in Doppler weather radar technology for operational applications by the participating agencies. The first two years of testing demonstrated the decisive superiority of Doppler techniques, in comparison with conventional methods, for reliable identification and early warning of tornadoes and other severe thunderstorm hazards. During the final year, the program evaluated the format and effectiveness of manually aided automatic display products transmitted in near-real time to operational agencies remotely located from the radar. Experiences of operating personnel utilizing these new techniques provide input toward system definition of NEXRAD, the Next Generation Weather Radar network now under development. One of the most encouraging examples of the enhanced warning capability realized by the remote transmission of the automated Doppler format was a successful forecast of severe weather for an Air Force Base which was a crucial factor in saving a fleet of aircraft from severe hail damage.
