Extractions: Tornadoes form from severe thunderstorms . They have a very high energy density which means that they affect a small area but are very destructive to that area. They also don't last very long which makes it hard to learn about them. Since they're hard to study, they're also hard to forecast . People know even less about tornadoes, which is why there are a lot of different myths that aren't true. Tornadoes can occur anywhere in the world. About 75% of them happen in the United States, most in an area know as Tornado Alley . There are also some other interesting facts about tornadoes. People who are interested in tornadoes sometimes become spotters for their community. Sometime people go out to Tornado Alley to chase tornadoes! After a tornado touches down, scientists try and figure out how strong it was by using the

http://www.msnbc.msn.com/id/22547648/

Extractions: REMINGTON, Ind. - Flooded rivers began withdrawing Wednesday across a swath of northern Indiana where three people were killed and hundreds of homes were damaged as melting snow and heavy rain swelled rivers during an unusual January warm streak. Six deaths were blamed on flooding and tornadoes across the Midwest on Monday and Tuesday, with the severe weather fueled by unseasonable temperatures. Tornadoes also blew through several states Monday and Tuesday. Two of the victims were young siblings. Water had started receding along Indiana's Tippecanoe River, which had risen to record levels along a 20-mile stretch, but numerous roads were still blocked by water in the Monticello area, said White County emergency management director Gordon Cochran. He had no immediate estimate for how many homes were damaged.

Extractions: Home About Us Contacts Help ... Feedback SEARCH Global Australia NSW Vic. ... Registered User Services Tornadoes occur more commonly in NSW than most people would expect. The Bureau of Meteorology's database records 364 tornadoes across NSW from 1795 to June 2003. Most tornadoes in NSW occur in late Spring and Summer but they have been known to occur at all times of the year. Tornadoes range in size from a few tens of metres across, up to around one kilometre in diameter. Because of this, damage is normally restricted to a small area, but is very intense. Tornadoes are thought to be formed by the interaction between regions of strong updrafts and downdrafts of air within severe thunderstorm clouds. Two views of the same tornado near Gilgandra, NSW on 29 September 1996. Tornadoes are ranked using the Fujita F-scale which estimates wind speed based on the extent and severity of damage. Below is the Fujita scale with respective approximate wind speeds. F-Scale rating Wind speed (km/h) Tornadoes seldom exceed F2 in Australia, but these are still quite damaging and dangerous. One of the highest wind speeds ever actually recorded in a tornado (using Doppler radar) was over 450 km/h in Oklahoma, USA in 1999. Stronger winds are evident from the examination of the impact of many tornadoes, particularly in the USA.
Introduction To Tornadoes

http://movies.warnerbros.com/twister/cmp/tornadointro.html

Extractions: A tornado (from the Spanish "tronada", meaning thunderstorm) is a violently rotating column of air rising up into a cloud. A thunderstorm is the first step in the creation of a tornado. A thunderstorm happens when there is moisture in the atmosphere, a lifting force causing air to begin rising, and unstable air that will continue to rise once it starts. Then, if other conditions are right, the thunderstorm may spin out one or more tornadoes. A tornado is often located at the edge of an updraft, next to air coming down from the thunderstorm with falling rain or hail. (This explains why a burst of heavy rain or hail sometimes announces a tornado's arrival.) As air rises from the ground in the tornado's vortex, a low pressure area is created near the ground. Air rushes to fill this area, causing additional damage to areas not directly hit by the tornado. As air rushes into the vortex, its pressure lowers, cooling the air. This cooling condenses water vapor in the air into the tornado's familiar funnel-shaped cloud. As the swirling winds pick up dust, dirt, and debris from the ground, the funnel turns even darker. (Twisters that pick up little dirt can retain their white, cloud coloration, and some have taken on a red hue by picking up red dirt.)

The strongest tornadoes may sweep houses from their foundations, destroy brick buildings, toss cars and school buses through the air, and even lift railroad cars from their tracks. Tornadoes vary in diameter from tens of meters to nearly 2 km (1 mi), with an average diameter of about 50 m (160 ft). Most tornadoes in the northern hemisphere create winds that blow counterclockwise around a center of extremely low atmospheric pressure . In the southern hemisphere the winds generally blow clockwise. Peak wind speeds can range from near 120 km/h (75 mph) to almost 500 km/h (300 mph). The forward motion of a tornado can range from a near standstill to almost 110 km/h (70 mph).

Extractions: With the amount of media coverage dedicated to American storm-chasers, you'd think the US had the monopoly on these twisters. It doesn't. It might come as a shock, but the United Kingdom is actually the world's most tornado-prone nation. This fact was calculated by the late Dr Fujita of Chicago University. He devised the standard method of measuring tornado intensity. Fujita figured that since Britain has an average of 33 tornadoes every year in an area 38 times smaller than the USA, you're twice as likely to witness a tornado here. How tornadoes happen

Extractions: This feature requires Flash, a free software plug-in, and JavaScript. Install Flash or see this feature's Non-interactive version Forecasters and researchers following a developing hurricane can accurately measure and rate its strength soon after it begins by collecting data from storm-hunting airplanes, radars, and satellites. But experts have no similar way to judge a tornado's force before or during its touchdown, as tornadoes arise too quickly and are too dangerous to approach by airplane. Instead, after a tornado hits, the U.S. National Weather Service uses a rating system it adopted in 1973 called the Fujita Scale. Devised by meteorologist Theodore Fujita in 1970, the F-scale enables experts to estimate a tornado's maximum wind speed in relation to the single most destructive thing it did. In this interactive, use the F-scale to examine and rate the destruction caused by several recent tornadoes. To launch the interactive Lexi Krock

Extractions: A tornado is a dark funnel-shaped cloud made up of violently rotating winds that can reach speeds of up to 300 m.p.h. The diameter of a tornado can vary between a few feet and a mile, and its track can extend from less than a mile to several hundred miles. Tornadoes generally travel in a northeast direction (depending on the prevailing winds) at speeds ranging from 20-60 m.p.h.

Extractions: Photographer Carsten Peter hangs halfway out the window of the other speeding car, which is driven by veteran storm chaser Gene Rhoden. With them is another kind of probe, a pyramid-shaped aluminum casing loaded with a video and three 35-mm still cameras. Tinman, the team calls it, based on the character from The Wizard of Oz. The chasers can hear the tornado's jet engine roar and see it snapping power poles as they veer east onto a paved road, past the Geyers' farm and directly into the path of the funnel. Tim skids to a halt to make a drop. "We don't have time! We don't have time!" Pat yells. The monster is plowing up ground only a hundred yards away, and the inflow wind is revving up as Tim leaps out just long enough to deposit a probe before scrambling back in. As the chasers speed away, they can see debris roaring in above them: Nails, wire, two-by-fours whip by in winds that will soon reach 200 miles (300 kilometers) an hour.
