The world's most violent cyclones; unpredictable columns of wind rotating at speeds exceeding 300miles per hour forming from specific atmospheric conditions. These conditions are a southerly flow of warm, moist air and a high-level westerly flow of cool, dry air. This combination produces an unstable atmosphere capable of strong updrafts and heavy precipitation. Tornadoes can develop on any type of terrain like mountains, valleys, deserts and swamps. They are common in spring and summer, but regardless of the time, if the conditions are right, a tornado will result. The cyclone forms when the air in the updraft of a severe thunderstorm begins to rotate owing to the formation of a low-pressure center. If the rotation reaches the ground, the funnel cloud sucks up air like a vacuum cleaner known to physicists as the conservation of angular momentum. The phenomenon allows the funnel cloud of a tornado to form a tight circle in which wind blows speeds greater than 500km/h. From the time they begin to the time they decipitate, they usually travel 10km, however, and some have been known to travel around 200-

With over 1,000 tornadoes recorded annually nationwide, it is no wonder that this severe natural disaster has a great effect on humans. Harsh tornadoes can devastate entire countries and literally brings a cities productivity to a halt. Many people are injured and killed from the tornado path, while others die from grief, or shock of the whole ordeal of having their life ripped apart and family members lost. Tornadoes do not only damage families, houses, buildings and the history of a city, but the economic structure suffers greatly. The damage and grief caused by tornadoes is never forgotten as the after-math of re-building the city structure and re-establishing business takes a while. The debris and wreckage alone takes a numerous amount of effort by firemen and wreckage crews to clean up. A plain example of the damage tornadoes can cause is what happened on April 21,1967, Chicago,IL. The intense storm system of 19 tornadoes that moved through the Midwest on that day produced tornadoes with winds speeds reaching between 207-260 mph and destruction and damages near $50 million. The worst part is that it took the lives of 58 people and injured hundreds more, many which could have been saved with more awareness and preparation in times of disaster. This is disaster that will be remembered for a long time. Hopefully in the near future the damage that tornadoes have caused annually will be reduced
