"Tornadoes have struck every U.S. state, including Alaska and Hawaii. But
most tornadoes form in a belt from Nebraska southward through central
Texas known as "Tornado Alley" and in the Southeast. Wind speeds in
tornadoes can vary from 72 to almost 300 mph." From: USA

- American Association for
- The American Association for Wind Engineering has promoted and
disseminated research results in the field of wind engineering since 1970.
The multi-disciplinary field of wind engineering encompasses problems
related to wind loads on buildings and structures, societal impacts of
hurricanes and tornadoes, risk assessment and cost-benefit, codes and
standards, dispersion of urban and industrial pollution, wind engineering
and urban aerodynamics.

improving the nation's severe weather warnings and forecasts.
- Storm Chaser Homepage
- October 5, 2000 marks the first official day of the new Storm Track
Storm Chaser Homepage. This new site is an official merger of the old

- Storm Prediction Center
- The Storm Prediction Center (SPC) is part of the National Weather
Service (NWS) and the National Centers for Environmental Prediction
(NCEP). Its mission is to provide timely and accurate forecasts and
watches for severe
thunderstorms and tornadoes over the contiguous United States. It uses the
most advanced technology
and scientific methods available to achieve this goal.

Overpasses as Tornado Shelters:
Fallout From the 3 May 1999 Oklahoma/Kansas Violent Tornado
- This National Severe Storms Laboratory and National Weather Service
report on the effectiveness
of using the undersides of highway overpasses as shelters from tornadoes
and other severe storms concludes that the
public has wrongly identified such areas as appropriate shelters. In
fact, they are extremely dangerous places in which to hide, and the public
should be educated about the danger of such shelters.

- The mission of the "Why Files" is to "explore the issues of science,
math, and technology that lurk behind the headlines of the day." Founded
in 1996 as a project of the National Institute for Science Education with
support from the National Science Foundation and produced by the Graduate
School of the University of Wisconsin, the files include this section
which provides background information on tornadoes. Included are an
explanation of these phenomena and
information on prediction, personal protection, and tornado effects on the
