Book Synopsis Weather Radar Technology Beyond NEXRAD by : National Research Council
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.

Available in PDF, EPUB and Kindle. Book excerpt: Meteorology is by nature a multidisciplinary and transnational subject and COST cooperation has proved to be a flexible and suitable framework at European level for meteorological activities such as the standardisation of observation techniques and harmonised transmission of meteorological data. Although meteorology is not covered by a specific Community programme as such, various Community actions dealing with meteorology are now included in the EEC research programme on climatology (the "EPOCH" programme - 1989-92) of mechanisms of extreme and sudden concerning particularly the study meteorological events, in order to predict catastrophies and consequently to reduce human and material losses. In the context of COST cooperation, which is supported by the Commission of the European Communities, the COST 73 project (1986-1991) associates 16 countries in Western Europe with the aim of setting up a weather radar network providing real-time measurements of rain, snow or hail precipitations. In this project, radar data are transmitted and combined if appropriate with satellite data - in one or more "compositing centres" of the participating countries, in order to improve weather forecasting. Together with the COST 73 Management Committee, the Commission of the European Communities organized a seminar on this matter, in Brussels on 5-8 September 1989, at the half-way stage of the project.

Book Synopsis Weather Radar Networking by : D.H. Newsome
Download or read book Weather Radar Networking written by D.H. Newsome and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past twenty years, there has been a rapid expansion in the number of opera tional, digital weather radars in Europe. Work within COST 73 stimulated the use of data from these radars and also demonstrated the potential of the international exchange of weather radar data in near real-time. The Management Committee of the COST 73 Project have laid the foun dations upon which future international operational radar networking may be built in Europe, and has indicated the directions that future weather radar technological developments might take. Throughout this five year Project, it has been possible to achieve success o~ through the goodwill of the participants. The considerable international co-operation is, in no smaIl measure, the underpinning reason why the Management Committee of COST 73 have been able to address such a wide range of topics within the general category of international weather radar networking. It has been an honour to have had the opportunity to act as Chairman of a group of meteorolo gists, engineers and managers possessing such a wide variety of talents and experience. I would like to take this opportunity to thank them all for their many and varied contributions.

Book excerpt: International Weather Radar Networking covers all aspects of the subject in a collection of contributions drawn from all over the world. Of particular interest are the papers describing work in Eastern Europe and papers reviewing of the achievements of the Commission of the European Communities COST-73 project. During the last twenty years there has been a rapid growth in the number of digital radars deployed for operational use in Western Europe. There are now around 100, of which about half have a Doppler capability, providing wind as well as reflectivity information. The international exchange of the data from these systems promises a great enhancement of the benefits to weather forecasting and commercial users. This volume reports work being undertaken to realize those benefits and points the way to future developments of radar technology.

Book Synopsis Flash Flood Forecasting Over Complex Terrain by : National Research Council
Download or read book Flash Flood Forecasting Over Complex Terrain written by National Research Council and published by National Academies Press. This book was released on 2005-01-28 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nation's network of more than 130 Next Generation Radars (NEXRADs) is used to detect wind and precipitation to help National Weather Service forecasters monitor and predict flash floods and other storms. This book assesses the performance of the Sulphur Mountain NEXRAD in Southern California, which has been scrutinized for its ability to detect precipitation in the atmosphere below 6000 feet. The book finds that the Sulphur Mountain NEXRAD provides crucial coverage of the lower atmosphere and is appropriately situated to assist the Los Angeles-Oxnard National Weather Service Forecast Office in successfully forecasting and warning of flash floods. The book concludes that, in general, NEXRAD technology is effective in mountainous terrain but can be improved.
Book Synopsis The Use of Digital Radar in Short-range Forecasting by : H. Stuart Muench
Download or read book The Use of Digital Radar in Short-range Forecasting written by H. Stuart Muench and published by . This book was released on 1976 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a program to improve short-range forecasts of weather conditions at aircraft terminals, a digital radar system was established at Air Force Geophysics Laboratory, Bedford Mass. The system, consisting of AN/FPS-77, digital interface, microwave transmitter-receiver, video integrator and computer, was installed in late 1972. Since that time the system has been used in conjunction with a network of 26 automated weather stations to make experimental forecasts of visibility and severe-weather conditions. The radar output of digital maps of radar intensity was found to be very convenient, but the inability of the radar to detect small water droplets limits the use in low visibility forecasting primarily to heavy rain storms and snow storms. In severe storms modest success was attained forecasting gusts, using digital maps. The large amounts of weather information from the network and radar frequently saturated the forecaster making forecasts at 15-min intervals, and relief was sought in the form of objective aids. Preliminary relationships between radar intensity, extinction coefficient (visibility) and rainfall rate have been formulated. In addition, a technique was developed using digital radar maps to obtain motion vectors and make probability forecasts of severe weather conditions. The calibration procedure relies on intensity of ground targets (hills and towers) for day-to-day relative calibration, and absolute calibration has been limited to Z-R relations. (Author).
