Book Synopsis Short Term Forecasting of Cloud and Precipitation Along Communication Paths by : Alan R. Bohne
Download or read book Short Term Forecasting of Cloud and Precipitation Along Communication Paths written by Alan R. Bohne and published by . This book was released on 1985 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: A methodology for real-time operations has been developed for the short-term forecasting of cloud and precipitation fields. Pattern recognition techniques are employed to extract useful features from the data field and extrapolation techniques are used to project these features into the future. To reduce computational load, contours defined by directional codes are used to delineate features. These contours are subdivided and attributes such as length, location, and location of each segment are determined. Segment matching is performed for successive observations and attribute changes are monitored over time. Several techniques for the forecasting of attributes have been explored, and an exponential smoothing filter and a linear trend adaptive smoothing filter have been chosen as most appropriate. Currently analysis is performed on a minicomputer and image processor system utilizing radar reflectivity data. Refinement of these techniques and extension into a more comprehensive short term forecasting program is planned. Keywords: Now casting, Pattern recognition, Extrapolation, Forecasting, Radar, Data filtering, Contour, Segmentation. (SDW)

Book Synopsis The Remote Atmospheric Probing Information Display (RAPID) System by : P. A. Sadoski
Download or read book The Remote Atmospheric Probing Information Display (RAPID) System written by P. A. Sadoski and published by . This book was released on 1988 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The RAPID system has been developed to support short term forecasting of cloud and precipitation. RAPID was developed with the philosophy that the system should be easily maintained, user-friendly, yet powerful enough to perform both the analysis or radar and satellite data and generation of forecasts in real-time. The two major hardware components are a VAX host computer and an ADAGE RDS-3000 image processor. The RAPID user environment is structured to encourage user participation. Numerous standardization procedures are employed: a functional disk organization, standardized data and source file headers, extensive file documentation, and use of user developed RAPID tools, libraries of often used routines. Data management has been designed to maximize the potential for real time capability. Radar and satellite data are preprocessed on other computers before ingestion into RAPID. The bulk of these data and derived products are stored, and analysis and display are performed entirely within, the image processor.

Download or read book Telecommunications Engineer's Reference Book written by Fraidoon Mazda and published by Butterworth-Heinemann. This book was released on 2014-06-28 with total page 1140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Telecommunications Engineer's Reference Book maintains a balance between developments and established technology in telecommunications. This book consists of four parts. Part 1 introduces mathematical techniques that are required for the analysis of telecommunication systems. The physical environment of telecommunications and basic principles such as the teletraffic theory, electromagnetic waves, optics and vision, ionosphere and troposphere, and signals and noise are described in Part 2. Part 3 covers the political and regulatory environment of the telecommunications industry, telecommunication standards, open system interconnect reference model, multiple access techniques, and network management. The last part deliberates telecommunication applications that includes synchronous digital hierarchy, asynchronous transfer mode, integrated services digital network, switching systems, centrex, and call management. This publication is intended for practicing engineers, and as a supplementary text for undergraduate courses in telecommunications.

Download or read book The Atmospheric Sciences written by Board on Atmospheric Sciences and Climate and published by National Academies Press. This book was released on 1998-11-05 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technology has propelled the atmospheric sciences from a fledgling discipline to a global enterprise. Findings in this field shape a broad spectrum of decisions--what to wear outdoors, whether aircraft should fly, how to deal with the issue of climate change, and more. This book presents a comprehensive assessment of the atmospheric sciences and offers a vision for the future and a range of recommendations for federal authorities, the scientific community, and education administrators. How does atmospheric science contribute to national well-being? In the context of this question, the panel identifies imperatives in scientific observation, recommends directions for modeling and forecasting research, and examines management issues, including the growing problem of weather data availability. Five subdisciplines--physics, chemistry, dynamics and weather forecasting, upper atmosphere and near-earth space physics, climate and climate change--and their status as the science enters the twenty-first century are examined in detail, including recommendations for research. This readable book will be of interest to public-sector policy framers and private-sector decisionmakers as well as researchers, educators, and students in the atmospheric sciences.

Download or read book Weather written by Gregory J. Hakim and published by Cambridge University Press. This book was released on 2021-10-28 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of this concise, affordable textbook is ideal for curious undergraduate majors and non-majors taking a first course in meteorology. The first two chapters introduce readers to the main concepts and tools used to analyze weather patterns. Chapters 3-8 provide a foundational understanding of the fundamental processes taking place in the atmosphere, and in Chapters 9-12 these physical concepts are applied to specific weather phenomena. Weather concepts are then used in Chapters 13-15 to explain weather forecasting, air pollution, and the impact of climate change on weather. Key concepts are illustrated through a running case study of a single mid-latitude cyclone, providing students with an opportunity to progressively develop their understanding of weather phenomena with a familiar example approached from multiple perspectives. This edition includes expanded and updated coverage of precipitation types and formation, satellite and radar technology, tornadoes, and more. It also features thought-provoking end-of-chapter review questions, new visual analysis exercises, an expanded test bank and nearly 100 new figures.

Download or read book Next Generation Earth System Prediction written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-08-22 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the nation's economic activities, security concerns, and stewardship of natural resources become increasingly complex and globally interrelated, they become ever more sensitive to adverse impacts from weather, climate, and other natural phenomena. For several decades, forecasts with lead times of a few days for weather and other environmental phenomena have yielded valuable information to improve decision-making across all sectors of society. Developing the capability to forecast environmental conditions and disruptive events several weeks and months in advance could dramatically increase the value and benefit of environmental predictions, saving lives, protecting property, increasing economic vitality, protecting the environment, and informing policy choices. Over the past decade, the ability to forecast weather and climate conditions on subseasonal to seasonal (S2S) timescales, i.e., two to fifty-two weeks in advance, has improved substantially. Although significant progress has been made, much work remains to make S2S predictions skillful enough, as well as optimally tailored and communicated, to enable widespread use. Next Generation Earth System Predictions presents a ten-year U.S. research agenda that increases the nation's S2S research and modeling capability, advances S2S forecasting, and aids in decision making at medium and extended lead times.
