This book was released on 2012 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: For decades, the National Weather Service (NWS) issued tornado warnings on a county-level. As a result, an entire county would be warned, even if only a small portion of the population was in danger. Over-warning for tornado threats can lead to a very dangerous sense of complacency amongst the public. On October 1, 2007, the agency converted to issuing storm-based warnings, through which meteorologists would design a unique warning area (shaped as a polygon) that projects the general path they expect a tornado or potentially tornadic storm cell to take. In theory, this approach limits the warning audience to the part of a county that could be directly impacted by a tornado. Narrowing the warning should reduce the impact of false alarms, as well as enable individuals to better assess the risk of harm and the value of taking shelter, thereby reducing the number of expected tornado casualties. Using regression analysis, this thesis tests to see if the way in which the NWS uses geography to communicate proximity to tornado risk has an effect on expected casualties. The effect of reducing the warning area size is controlled for by incorporating into the model the average county area reduction score for each county tornado event. This variable failed to achieve significance. Consequently, the thesis cannot conclude that the switch to storm-based warnings has had a statistically significant effect on reducing or increasing expected casualties. The lack of significance could be attributed to insufficient data, although the dataset contains nearly all county tornado events since the policy took effect. An alternative explanation is that most of the current warning dissemination systems are incapable of only alerting individuals located within the unique boundaries of the polygon.

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.

This book was released on 2024-01-16 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preparedness takes action! Learn more about hazards which can affect your community and ways you can take action to prepare and participate: Earthquakes can occur suddenly and be deadly. Most earthquake-related casualties result from collapsing walls, flying glass, and falling objects. Flooding is the most common natural disaster in the United States and can happen anywhere. Hurricanes have the power to cause widespread devastation, and can affect both coastal and inland areas. Tornadoes are one of nature's most violent storms, and can cause death, injury, and destruction within seconds. Wildfires can occur anywhere and can destroy homes, businesses, infrastructure, natural resources, and agriculture. Winter storms can occur anywhere and bring freezing rain, ice, snow, high winds or a combination of all these conditions. They can cause power outages that last for days or weeks; making it hard to keep warm and making travel very dangerous. Recent national tragedies remind us that the risk is real: an active shooter incident can happen in any place at any time. The best way to make sure you and your loved ones stay safe is to prepare ahead of time.

Download or read book Verification and Analysis of Impact based Tornado Warnings in the Central Region of the National Weather Service written by Holly B. Obermeier and published by . This book was released on 2014 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tornado warnings are one of the most critical products issued by the National Weather Service (NWS), and favorable verification statistics are desirable. The 2011 NWS statistics for traditional tornado warnings indicate that the probability of detection (POD) is 70%, while the false alarm rate (FAR) is 76%. The recent Joplin, Missouri EF5 tornado event on 22 May 2011, which resulted in massive devastation and loss of life, prompted the NWS to re-evaluate the current tornado warning format. After the Joplin, MO event, the Central Region of the NWS implemented the impact-based tornado warning (IBTW) experiment in 2013. IBTWs consist of tiers including damage tags and impact wording which convey increasing levels of damage. The damage wording within an IBTW is shown to relate to the Enhanced Fujita (EF) Scale. Wording included in non-tagged IBTWs corresponds to EF0-EF2 tornado damage, while the damage wording for tagged IBTWs corresponds to EF3-EF5 tornado damage. This study investigates the accuracy of IBTWs by examining if a tornado occurs during the warning time frame, and whether the resulting damage matches the damage wording in the IBTW. All IBTWs from 1 April 2013 through 30 November 2013 are collected, as well as tornado survey information, including EF Scale intensity, for every tornado which occurred in the Central Region during the same time period. Using these survey data, IBTWs are verified by the intensity of the tornado, if one occurs. POD and FAR statistics are calculated through 2x2 contingency tables for both non-tagged and tagged IBTWs. Results indicate that the majority of both non-tagged and tagged IBTWs are false alarms, and tagged IBTWs have a very low POD. Case studies of several events explore successful and unsuccessful implementation of damage tags, revealing that limitations in current technology and scientific knowledge may contribute to false alarms and missed detections. These findings suggest that more advances in technology and the understanding of tornadogenesis are necessary for more successful implementation of IBTWs.

Download or read book Natural Hazards written by Edward A. Keller and published by Routledge. This book was released on 2019-03-29 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new revised fifth edition of Natural Hazards remains the go-to introductory-level survey intended for university and college courses that are concerned with earth processes that have direct, and often sudden and violent, impacts on human society. The text integrates principles of geology, hydrology, meteorology, climatology, oceanography, soil science, ecology, and solar system astronomy. The textbook explains the earth processes that drive hazardous events in an understandable way, illustrates how these processes interact with our civilization, and describes how we can better adjust to their effects. Written by leading scholars in the area, the new edition of this book takes advantage of the greatly expanding amount of information regarding natural hazards, disasters, and catastrophes. The text is designed for learning, with chapters broken into small consumable chunks of content for students. Each chapter opens with a list of learning objectives and ends with revision as well as high-level critical thinking questions. A Concepts in Review feature provides an innovative end-of-chapter section that breaks down the chapter content by parts: reviewing the learning objectives, summary points, important visuals, and key terms. New case studies of hazardous events have been integrated into the text, and students are invited to actively apply their understanding of the five fundamental concepts that serve as a conceptual framework for the text. Figures, illustrations, and photos have been updated throughout. The book is designed for a course in natural hazards for nonscience majors, and a primary goal of the text is to assist instructors in guiding students who may have little background in science to understand physical earth processes as natural hazards and their consequences to society.
