This revision of the first edition of Technical Paper No. 20 extends the data to included the years 1951 through 1958 and contains additional textual material, tabulations, and charts.
With 16 pages of black-and-white illustrations In Storm Kings, Lee Sandlin retraces America's fascination and unique relationship to tornadoes and the weather. From Ben Franklin's early experiments, to "the great storm debates" of the nineteenth century, to heartland life in the early twentieth century, Sandlin shows how tornado chasing helped foster the birth of meteorology, recreating with vivid descriptions some of the most devastating storms in America's history. Drawing on memoirs, letters, eyewitness testimonies, and numerous archives, Sandlin brings to life the forgotten characters and scientists that changed a nation and how successive generations came to understand and finally coexist with the spiraling menace that could erase lives and whole towns in an instant.
For almost a decade, economists Kevin M. Simmons and Daniel Sutter have been studying the economic effects and social consequences of the approximately 1,200 tornadoes that touch down across the United States annually. During this time, they have compiled information from sources such as NOAA and the U.S. Census Bureau to examine the casualties caused by tornadoes and to evaluate the National Weather Service (NWS)’s efforts to reduce these casualties. Their unique database has enabled this fascinating and game-changing study for meteorologists, social scientists, emergency managers, and everyone studying severe weather, policy, disaster management, or applied economics.
This highly illustrated book is a collection of 13 review papers focusing on convective storms and the weather they produce. It discusses severe convective storms, mesoscale processes, tornadoes and tornadic storms, severe local storms, flash flood forecast and the electrification of severe storms.
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.
As climate has warmed over recent years, a new pattern of more frequent and more intense weather events has unfolded across the globe. Climate models simulate such changes in extreme events, and some of the reasons for the changes are well understood. Warming increases the likelihood of extremely hot days and nights, favors increased atmospheric moisture that may result in more frequent heavy rainfall and snowfall, and leads to evaporation that can exacerbate droughts. Even with evidence of these broad trends, scientists cautioned in the past that individual weather events couldn't be attributed to climate change. Now, with advances in understanding the climate science behind extreme events and the science of extreme event attribution, such blanket statements may not be accurate. The relatively young science of extreme event attribution seeks to tease out the influence of human-cause climate change from other factors, such as natural sources of variability like El Niño, as contributors to individual extreme events. Event attribution can answer questions about how much climate change influenced the probability or intensity of a specific type of weather event. As event attribution capabilities improve, they could help inform choices about assessing and managing risk, and in guiding climate adaptation strategies. This report examines the current state of science of extreme weather attribution, and identifies ways to move the science forward to improve attribution capabilities.
A guide to tornado formation and lifecycle also covers such topics as forecasting, wind speeds, tornado myths, tornado safety, risks, and records, along with accounts of the deadliest tornadoes in the United States.
