This workshop report examines the capability of the forecast system to efficiently transfer weather and climate research findings into improved operational forecast capabilities. It looks in particular at the Environmental Modeling Center of the National Weather Service and environmental observational satellite programs. Using these examples, the report identifies several shortcomings in the capability to transition from research to operations. Successful transitions from R&D to operational implementation requires (1) understanding of the importance (and risks) of the transition, (2) development and maintenance of appropriate transition plans, (3) adequate resource provision, and (4) continuous feedback (in both directions) between the R&D and operational activities.
Following a series of natural disasters, including Hurricane Katrina, that revealed shortcomings in the nation's ability to effectively alert populations at risk, Congress passed the Warning, Alert, and Response Network (WARN) Act in 2006. Today, new technologies such as smart phones and social media platforms offer new ways to communicate with the public, and the information ecosystem is much broader, including additional official channels, such as government social media accounts, opt-in short message service (SMS)-based alerting systems, and reverse 911 systems; less official channels, such as main stream media outlets and weather applications on connected devices; and unofficial channels, such as first person reports via social media. Traditional media have also taken advantage of these new tools, including their own mobile applications to extend their reach of beyond broadcast radio, television, and cable. Furthermore, private companies have begun to take advantage of the large amounts of data about users they possess to detect events and provide alerts and warnings and other hazard-related information to their users. More than 60 years of research on the public response to alerts and warnings has yielded many insights about how people respond to information that they are at risk and the circumstances under which they are most likely to take appropriate protective action. Some, but not all, of these results have been used to inform the design and operation of alert and warning systems, and new insights continue to emerge. Emergency Alert and Warning Systems reviews the results of past research, considers new possibilities for realizing more effective alert and warning systems, explores how a more effective national alert and warning system might be created and some of the gaps in our present knowledge, and sets forth a research agenda to advance the nation's alert and warning capabilities.
From the heart of tornado alley, Smith takes us into the eye of America's most devastating storms and behind the scenes of some of the world's most renowned scientific institutions to uncover the relationship between mankind and the weather.
This illustrated guide showcases some facts about weather-related events and suggests life-saving actions you can take, if you find yourself in an unexpected situation resulting from a weather-related event. The goal of this booklet is to present you with details on how to recognize severe weather, be aware of your surroundings, and to encourage you to develop a plan to be ready to act when threatening weather approaches. Here is a bird's eye-view of the weather-related events that are covered in this guide with a few short facts about each that are also presented in the guide. Lightning... ¦ Causes an average of 55-60 fatalities and 400 injuries each year ¦ Occurs with all thunderstorms ¦ Costs more than $1 billion in insured losses each year Tornadoes... ¦ Cause an average of 60-65 fatalities and 1,500 injuries each year ¦ Can produce wind speeds in excess of 200 mph ¦ Can be 1 mile wide and stay on the ground over 50 miles Straight-line Winds... ¦ Can exceed 125 mph ¦ Can cause destruction equal to a tornado ¦ Are extremely dangerous to aviation Flash Floods and Floods... ¦ Are the #1 cause of deaths associated with thunderstorms, more than 90 fatalities each year Hail... ¦ Can be larger than a softball (5 inches in diameter) ¦ Causes more than $1 billion in crop and property damage each year Some helpful tips included in this guide include how quickly these weather-events can result to a devastating situation. Therefore, it emphasizes that by having a plan in place prior to the event that is practiced from time to time, will allow response actions to be positive rather than stressful. This resource also provides guidance on the type of items that should be included in an Emergency Supply Kit for use at home, office, school, or place of business. There is also a special section dedicated to schools and working with children during an unexpected weather emergency. This school section also includes proper inspections and maintenance of buildings, and recommends emergency drills to practice the school safety plans with children including handling of disabled personnel and/or children.
Since the dawn of medical science, people have recognized connections between a change in the weather and the appearance of epidemic disease. With today's technology, some hope that it will be possible to build models for predicting the emergence and spread of many infectious diseases based on climate and weather forecasts. However, separating the effects of climate from other effects presents a tremendous scientific challenge. Can we use climate and weather forecasts to predict infectious disease outbreaks? Can the field of public health advance from "surveillance and response" to "prediction and prevention?" And perhaps the most important question of all: Can we predict how global warming will affect the emergence and transmission of infectious disease agents around the world? Under the Weather evaluates our current understanding of the linkages among climate, ecosystems, and infectious disease; it then goes a step further and outlines the research needed to improve our understanding of these linkages. The book also examines the potential for using climate forecasts and ecological observations to help predict infectious disease outbreaks, identifies the necessary components for an epidemic early warning system, and reviews lessons learned from the use of climate forecasts in other realms of human activity.
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.
This book presents a summary of the Workshop on Public Response to Alerts and Warnings on Mobile Devices: Current Knowledge and Research Gaps, held April 13 and 14, 2010, in Washington, D.C., under the auspices of the National Research Council's Committee on Public Response to Alerts and Warnings on Mobile Devices: Current Knowledge and Research Needs. The workshop was structured to gather inputs and insights from social science researchers, technologists, emergency management professionals, and other experts knowledgeable about how the public responds to alerts and warnings, focusing specifically on how the public responds to mobile alerting.
