41. The Cause Of Tornadoes.
    tornadoes are caused by clouds rising and creating a vacuum below them.  
    http://www.nov55.com/tor.html
    
    Extractions: The Cause of Tornadoes Vortexes are created by a fluid rushing in a horizontal direction. This effect is readily observable with whirlpools in a river. Such a horizontal rush of air is consistent with the characteristics of tornadoes. Tornadoes are caused when a cloud of the right size precipitates rapidly releasing heat, which causes it to rise, and creates a vacuum under it. Air rushing under it creates the vortex. It is known that a sudden drop in air pressure precedes tornadoes. The pressure drop is caused by a cloud near the ground rising rapidly creating a partial vacuum below it. The vacuum seems to be quite noticeable, as persons who were near tornadoes often mention it. Precipitation releases as much heat as evaporation absorbs. But precipitation tends to be much faster than evaporation. So a very large amount of heat is released when a cloud precipitates. Heat of course causes air to rise. When a cloud near the ground rises, it creates a partial vacuum under it. The cloud must be the right size for a tornado to occur. A very large cloud would not precipitate uniformly, so the whole cloud would not rise at once. A very small cloud would not produce enough precipitation or heat to create a large enough vacuum for a tornado to form.

    Extractions: © Greg Stumpf 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 Enhanced Fujita Tornado Scale

    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.)

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

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.

    Extractions: TORNADOES OF THE 20TH CENTURY NOAA's Storm Prediction Center in Norman, Okla., have prepared a list of some of the more notable tornado outbreaks that occurred in the United States during the 20th century. The summary lists the tornadoes by decade and notes the technological and policy improvements that resulted. "For meteorologists who study tornadic storms either through forecasting or research or storm chasing, there are a number of memorable tornadoes or tornado outbreaks during the 1900s," said Dan McCarthy, warning coordination meteorologist for the Storm Prediction Center. "Many meteorologists are in the profession because of a certain outbreak or tornado that spurred their curiosity, driving them to the science." Technological advancements in the second half of the century have contributed to better, more accurate severe weather watches and warnings from the National Weather Service, ultimately saving countless lives. The biggest advancement for severe weather (forecasting was the development of Doppler radar. NOAA scientists and other researchers took the airborne radar developed by the U.S. military during World War II and applied it to weather forecasting and severe storm identification. The ultimate result was the Next Generation Radar (NEXRAD) Doppler weather radar system currently in use.

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.
