This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Severe thunderstorm warnings issued by the National Weather Service and severe thunderstorm weather reports dating from January 1, 1986 to December 31, 2005 were analyzed to find a potential county bias in the issuance of severe thunderstorm warnings. Choropleth maps and statistical analysis of the data reveal a population density bias for both severe weather reports and severe thunderstorm warnings issued as well as a likely distance bias. Additional non-meteorological county warning and severe weather report biases were found for several counties in the study area that may relate to socioeconomic factors, physiographic influences and county size and directional orientation. Proximity to interstate highways also appears to have an effect on the reporting of severe weather events and the issuance of severe thunderstorm warnings.

Download or read book Severe Thunderstorms and Tornadoes in the United States written by Peter Folger and published by DIANE Publishing. This book was released on 2011-04-10 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Severe thunderstorms and tornadoes affect communities across the U.S. every year, causing fatalities, destroying property and crops, and disrupting businesses. Tornadoes are the most destructive products of severe thunderstorms. Damages from violent tornadoes seem to be increasing, similar to the trend for other natural hazards in part due to changing population, demographics, and more weather-sensitive infrastructure and some analysts indicate that losses of $1 billion or more from single tornado events are becoming more frequent. Insurance industry analysts state that tornadoes, severe thunderstorms, and related weather events have caused nearly 57%, on average, of all insured catastrophe losses in the U.S. in any given year since 1953.

Download or read book Scanning the Skies written by Marlene Bradford and published by University of Oklahoma Press. This book was released on 2001 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tornadoes, nature's most violent and unpredictable storms, descend from the clouds nearly one thousand times yearly and have claimed eighteen thousand American lives since 1880. However, the U.S. Weather Bureau--fearing public panic and believing tornadoes were too fleeting for meteorologists to predict--forbade the use of the word "tornado" in forecasts until 1938. Scanning the Skies traces the history of today's tornado warning system, a unique program that integrates federal, state, and local governments, privately controlled broadcast media, and individuals. Bradford examines the ways in which the tornado warning system has grown from meager beginnings into a program that protects millions of Americans each year. Although no tornado forecasting program existed before WWII, the needs of the military prompted the development of a severe weather warning system in tornado prone areas. Bradford traces the post-war creation of the Air Force centralized tornado forecasting program and its civilian counterpart at the Weather Bureau. Improvements in communication, especially the increasing popularity of television, allowed the Bureau to expand its warning system further. This book highlights the modern tornado watch system and explains how advancements during the latter half of the twentieth-century--such as computerized data collection and processing systems, Doppler radar, state-of-the-art television weather centers, and an extensive public education program--have resulted in the drastic reduction of tornado fatalities.

This book was released on 2012 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research is to define the spatial distribution of short-fuse severe weather warnings as they relate to population density within the Contiguous United States (CONUS). Using Geographic Information Science and statistical techniques, the overall spatial pattern of National Weather Service (NWS) warning issuance was determined along with correlations to population distribution. Four basic short-fuse warning types were studied; severe thunderstorm county-based warnings, severe thunderstorm storm (polygon) based warnings, tornado county-based warnings, and tornado storm-based warnings. Severe weather warning and ambient population data were obtained from United States Government sources and were spatially joined to the United States Geological Survey's 7.5 minute, 1:24,000 (1:25,000 metric) Quadrangle Series. Counts of the number of warnings issued and population density for each Quadrangle in the CONUS were statistically compared to find correlations between the two data types. The direction of the center of mean warning distribution was compared to the geographic center of National Weather Service County Warning Areas to determine if a directional bias exists. This study finds that a spatial relationship to population exists for three warnings types: severe thunderstorm storm-based warnings, tornado county-based warnings and tornado storm-based warnings. Population bias statistical evidence is most prevalent for severe storm-based warnings. This study also finds that the spatial distribution of warnings has shifted with the transition to storm-based warnings from the central part of the Nation to the southeastern United States. The annual frequency of county-based severe and tornado warnings was highest for the Central Plains, where severe storm-based warnings were issued for distinctly defined county warning areas mainly in the south and southeastern United States. Tornado storm-based warnings were issued more frequently in the Deep South, southeast, and Gulf Coast areas. Several National Weather Service Weather Forecast Offices showed a tendency to have a high frequency of warnings when compared to neighboring NWS offices. Directional distribution varied drastically between weather forecast offices, but the overall tendency was for warnings to be issued to the south of the geographic center of National Weather Service County Warning Areas. Several weather forecast offices showed a tendency to issue more warnings in the up-range direction associated with climatological storm movement. Results from this study indicated that human influence is the main factor that contributes to warning frequency and spatial distribution.

This book was released on 1977 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: An operational test of Doppler radar as a real-time forecasting tool took place during Spring 1977 in Oklahoma. Participating groups included National Severe Storms Laboratory, National Weather Service, Air Weather Service and Air Force Geophysics Laboratory. The AFGL color display, mated to the NSSL 10-cm Cimarron Doppler radar, provided back-up capability to the center of operations at Norman. Also, the authors provided additional interpretation of the velocity patterns depicted on the color display for the benefit of the operational meteorologists participating in the test. Experiences in real-time identification of velocity patterns characteristic of hazardous weather are summarized in this paper. (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.
