The Windy Wonders' question regarding cyclones vs. tornadoes vs. hurricanes from 2/14/2000 is answered below. Hope this helps! -C. Duvall Rutgers Univ. Meteorologist 2/15/2000 A. Wind and Hurricanes: Please see the message I posted called " **Wind and Hurricanes Explained** " from 2/14/2000 B. Cyclones: A cyclone is any area where the winds are turning counter-clockwise, or in a circle to the left. This includes hurricanes, tornadoes, some thunderstorms, and other areas of Low pressure. Cyclones tend to produce stormy weather of some kind. People often use the word "cyclone" to describe one of the examples above, which is why you sometimes hear someone call a tornado a "cyclone". C. Tornadoes: Tornadoes are believed to be miniature cyclones, but scientists are still trying to gather evidence to figure them out. Dr. Howie Bluestein, a storm-chasing professor from the University of Oklahoma, has collected special radar images of tornadoes that show an eye inside of them, just like a hurricane! On the outside, some tornadoes look like thin ropes of spaghetti, others look like the one they drew for the end of the movie Twister. Some are invisible until they begin swirling up stuff from the ground. Tornadoes can produce the fastest, natural winds on Earth. Right before I left Oklahoma to come back to New Jersey, I saw my first tornado ever. It was the Moore, OK F5 tornado with the fastest recorded winds ever: 318 miles per hour ! 319 mph would be an F6, which has not officially been recorded yet. That was the first of about six or so that I happened to see the afternoon of May 3, 1999. One of the other Weather Specialists in our group- Andrew Wood- is also from the University of Oklahoma. I am pretty sure he saw the Moore, OK tornado, too. Students and scientists chase storms to study them, so we can figure out why they are created. The more we know, the better we will be at guessing when and where they will happen, next. That way, people will have more time to get out of the way. The same applies to the scientists who fly planes through hurricanes. A lot of people try to chase storms, especially after seeing Twister, but it is EXTREMELY dangerous! Even the scientists are very careful, and they are usually guided by special instruments and their own experiences with storms. By the way, you cannot survive an F5 tornado by belting yourself to a pipe like in Twister. The wind is bad, but it is the stuff flying around in the wind that does most of the actual damage. It was a cool movie, not real life. Just like the example I gave in my previous message, trees and hills help to slow down windy weather, which is one reason why tornadoes are more rare in hilly areas. Trees won't slow down a tornado very much- if that were true, people would turn Oklahoma into a forest! I saw whole neighborhoods in Moore where nothing higher than 3 feet existed after the tornado came through- this is why you have to get to the lowest floor, underground, or out of the way entirely when a tornado is coming. Finally, tornadoes and hurricanes are rare. They are not something you have to look out for every day. But when they do decide to visit, pay attention and stay safe. This was another good question... keep 'em coming! ---------------------------------------------
