As one of the most powerful naturally occurring phenomena, tornados cause significant damage to people and property each year. Although twisters cause such destruction, or perhaps because of this, people's fascination with them continues.

The Web reflects this by offering very good and interesting sites about tornados, the first of which is offered by Roger Edwards of the Storm Prediction Center of NOAA (1). This site offers basic information about tornados, describing what they are, how they form, how meteorologists forecast them, tornado damage information, and a lot more. Another site from NOAA is the National Severe Storms Laboratory Photo Album (2), which contains breathtaking photos of twisters in action, organized into an easy-to-use photo album format. The next site is Tornado Project Online (3), which describes itself as "a small company that gathers, compiles, and makes tornado information available to weather enthusiasts, the meteorological community and emergency management officials." The site has information about tornados that have occurred all over the world, as well as unique things such as Tornado Myths and Oddities links. From the University of Utah's Department of Meteorology Web site entitled Numerical Forecasts (4) comes a collection of forecasting model links. They are grouped into three categories: NCEP Models, MM5 Models, and Others. The site offers over thirty sites maintained by organizations conducting research. The next two sites are from the Federal Emergency Management Agency (FEMA). The first is entitled Tornado Safety Tips Brochure (5), which offers advice for people, such as what supplies you should have in case of a tornado and what to do if there is a tornado watch or warning. The next FEMA site is for kids and is entitled Tornadoes (6). This site is a fun and interactive way for kids to learn all about tornadoes and tornado safety. The next site, from the National Center for Atmospheric Research's Web site, Web Weather for Kids, is entitled Make a Tornado! (7). This hands-on experiment explains how to make your own tornado out of simple objects from around the house. The last site, from the Department of Atmospheric Sciences at the University of Illinois at Urbana-Champaign (8), offers a gallery of animations and movies of tornado activity. The page called Gallery of the Atmospheric Modeling Group at NCSA and the Convective Modeling Group at DAS/UIUC (9) has very cool animations and video clips of tornados doing their thing.
