Extractions: What is a tornado? How do tornadoes form? Before thunderstorms develop, a change in wind direction along with an increase of wind speed with increasing height creates an invisible, horizontal spinning effect in the lower atmosphere. Rising air within the thunderstorm updraft tilts the rotating air from horizontal to vertical. The area of rotation, 2-6 miles wide, now extends through much of the storm. This rotating column of air, known as a funnel extends from the cloud and grows downward toward the ground. Once the funnel touches the ground is becomes a tornado. Since the center of the funnel is a low pressure area, air rushes into the column and rises. The air is cooled as it rises and water vapor condenses to form the familiar funnel shaped cloud. As the rotating winds begin to pick up dirt and debris from the ground, the funnel will darken. The strongest tornadoes occur in supercell thunderstorms which can also produce large hail and strong downbursts.

tornadoes. Q How are tornadoes formed? A tornadoes are generallyformed in a thunderstorm. (Al Peterlin). Q How do tornadoes end?
http://teacher.scholastic.com/researchtools/articlearchives/weather/tornado.htm

Extractions: A: Tornadoes are generally formed in a thunderstorm. Thundershowers this violent require a complex mix of environmental conditions but usually include: a) very warm, humid air, b) very cool, dry air to the west and south, c) air to the west trying to replace the warm, moist air (a front moving in), c) upper level (high in the sky) conditions that first hold down warmer air from rising and then later, a complete reverse in conditions that let the warm air rise very fast and very far, and d) an upper level wind stream to move the air away from the rising column. This sounds complicated, but it really boils down to warm, wet air driven east by a strong cold front and what we call instability. (Al Peterlin) Q: What does the funnel of a tornado look like? A: A tornado is a rotating column of air that reaches from a thunderstorm cloud to the ground. If it doesn't reach the ground, it's called a funnel cloud because it's shaped like a funnel. The color is dark because of dust and dirt pulled up into it from the ground. (Al Peterlin) Q: How do tornadoes end?

Extractions: The Red River Valley Tornadoes of April 10, 1979 The following text comes from Chapter I of the NOAA Natural Disaster Report 80-1, "The Red River Valley Tornadoes of April 10, 1979." "To the people of the Red River Valley in Texas and Oklahoma, nothing about the weather appeared unusual during the early hours of April 10, 1979: it was business as usual. But before the day's end, three very large, devastating tornadoes swept across the area leaving scores dead and hundreds injured. Most of the deaths were in Wichita Falls and Vernon, Texas, and Lawton, Oklahoma." "Early on April 10, NWS forecasters became aware of the threat of severe weather. During the morning, closely monitored air mass movements, temperatures, dew points, and winds had all been shifting towards critical values indicative of severe thunderstorms and potential tornadoes. By noon, all doubt was gone. Forecasters at the National Severe Storms Forecast Center in Kansas City had to decide only how soon tornadoes would develop and how large an area would be threatened.

http://www.padrak.com/ine/ELEWIS3.html

Extractions: Tornadoes and Ball Lightning Abstract Tornadoes and ball lightning are identified, and described as plasmoid phenomena. Certain anomalous characteristics of tornadoes and ball lightning are described and shown to be similar to the behavior of the plasmoid phenomena produced by electrolysis and discharge apparatus; in part, as evidenced by certain kinds of micrometer sized traces in nuclear emulsions and marks in materials. Atmospheric Plasmoid Phenomena A weather observer for the U. S. Weather Service named F. Montgomery(10) who was stationed in Blackwell, Oklahoma in May of 1955 reported a tornado that passed by in the evening at 9:27 P.M. that had a deep blue section that was near the top near the cloud layer and that was "very much brighter" than an arc welder and too bright for him to look at, though the tornado was 9 blocks or 3600 feet away from him. I suspect that the bright section may have been toroid shaped. He reported that the air from the tornado felt hot and that the temperature as recorded by a thermometer at his instrument shelter rose from 74 degrees Fahrenheit to 80 degrees Fahrenheit when the storm struck. This is evidence of a spectacular rate of radiation. And he reported: There were rapidly rotating clouds passing in front of the top of the funnel. These clouds were illuminated only by the luminous band of light. The light would grow dim when these clouds were in front, and then it would grow bright again as I could see between the clouds. As near as I can explain, I would say that the light was the same color as an electric arc welder but very much brighter. The light was so intense that I had to look away when there were no clouds in front. The light and the clouds seemed to be turning to the right like a beacon in a lighthouse(11).

Extractions: May 3rd 1999 Central OK Tornadoes 3 May 2000 Tornado Sketch by Cheryl-Ann Tan If you want to put this pic on your site, please send e-mail It's one year since the devastating outbreak. The Weather Signposts presents a collection of links on the web with a touch of humanity on the tragic outbreak. The outbreak, the lessons learned, the victims... will not be forgotten. This outbreak was, in a way, one that has left the deepest impression on me. It was the first "really big one" that I had ever heard of while I existed on this planet. I read everything on the event that I could get my hands on for almost a year. Never did I realize that there was so much to a single outbreak. Like many, I tend to see such events as tests and lessons for people. There is a recent song which contained a line, "lessons learned and they sure run deep... don't come easy and they don't come cheap." This one wasn't cheap. In case you're new to the weather world, the Oklahoma City/Moore tornado in the May 3rd outbreak was the USA's first billion-dollar tornado. Shoddy building structures, forecasts and forecasters, warnings, precautions taken by the public... were all put to the test. Chase accounts Lets start here with chase logs... after all, they are the war stories from the front lines. If you haven't start looking over the links, I suggest you do that now. There isn't much else for me to say since I wasn't there myself... so I shall only make this more of compilation of links and my thoughts.

Extractions: Contact Us Hurricanes can also produce tornadoes that add to the storm's destructive power. Tornadoes are most likely to occur in the right-front quadrant of the hurricane. However, they are also often found elsewhere embedded in the rainbands , well away from the center of the hurricane. Some hurricanes seem to produce no tornadoes, while others develop multiple ones. Studies have shown that more than half of the landfalling hurricanes produce at least one tornado; Hurricane Buelah (1967) spawned 141 according to one study. In general, tornadoes associated with hurricanes are less intense than those that occur in the Great Plains (see the Fujita Intensity Scale below). Nonetheless, the effects of tornadoes, added to the larger area of hurricane-force winds, can produce substantial damage. We have no way at present to predict exactly which storms will spawn tornadoes or where they will touch down. The new Doppler radar systems have greatly improved the forecaster's warning capability, but the technology usually provides lead times from only a few minutes up to about 30 minutes. Consequently, preparedness is critical Tornado Facts When associated with hurricanes, tornadoes are not usually accompanied by hail or a lot of lightning, clues that citizens in other parts of the country watch for.
