Excerpt from History of Tornado Observations and Data Sources The updraft within the funnel cloud may have a speed of 100 or 200 miles an hour. (d) The speed of the storm itself in trav elling over the earth is comparatively slow-25 to 40 miles an hour; its path is short, averaging about 300 miles. 2. Name given in West Africa to the squall which accompanies a thunder storm. The 300 miles for the average length of the tornado path obviously is a mis print. The definition is interesting in that it states that the funnel-shaped cloud which marks the vortex as the storm moves along, may or may not touch the earth The Glossary also defines a funnel cloud stating that its small end reaches down toward the earth. The definition of the waterspout recognizes two classes of these one class being similar to a tornado in function and aspect.

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 is about weather extremes in the United Kingdom. It presents fascinating and detailed insights into tornadoes (supercell and non-supercell tornadoes, historical and contemporary case studies, frequency and spatial distributions, and unique data on extreme events); thunderstorms (epic event analysis and observing); hailstorms (intensity, distributions and frequency of high magnitude events); lightning (lightning as a hazard, impacts and injuries); ball lightning (definitions, impacts and case studies); flooding (historical and contemporary analysis, extreme rainfall and flash flooding); snowfalls (heavy snowfall days and events). It also looks at researching weather extremes, provides guidance on performing post-storm site investigations and details what is involved in severe weather forecasting. It is written by members, directors and past and present Heads of the research group the Tornado and Storm Research Organisation (TORRO). With fifteen chapters thematically arranged, and data appendix including a new tornado map of the U.K., this book presents a wealth of information on meteorological extremes. This volume is aimed primarily at researchers in the field of meteorology and climatology, but will also be of interest to advanced undergraduate students taking relevant courses in this area.
