The Summer Season , from June until September has the highest frequencies with usual intensities of or on the Fujita Scale . This includes those tornadoes that form from landfalling Tropical Cyclones. The Deadly Spring Season , from February through April is characterized by more powerful tornadoes because of the presence of the jet stream. When the jet stream digs south into Florida and is accompanied by a strong cold front and a strong squall line of thunderstorms, the jet stream's high level winds of 100 to 200 mph often strengthen a thunderstorm into what meteorologists call a supercell or mesocyclone. These powerful storms can move at speeds of 30 to 50 mph, produce dangerous downburst winds, large hail and the most deadly tornadoes. What Time Are Florida's Tornadoes Likely to Strike?

There were no reports of injuries. Two tornadoes struck Scott County south of Minneapolis and one hit Rice County, skipping over the campus of Carleton College in Northfield and hitting a turkey farm. Another was reported in Carver County, as well as one in Goodhue County along the Wisconsin border. Emergency official John Elder said storms intensified after an otherwise nice, spring Minnesota day. "This stuff just whipped up basically out of nowhere," he said. The storm tore the roof off this rural home In Northfield, Eric Sieger, a spokesman for Carleton College, said sirens echoed across campus as a tornado hopped over them. He said the school suffered only minor damage, such as downed tree limbs.

FUNDAMENTALS OF PHYSICAL GEOGRAPHY HOME FUNDAMENTALS ONLINE TEXTBOOK GLOSSARY ... ABOUT CHAPTER 7: Introduction to the Atmosphere (t). Thunderstorms and Tornadoes Thunderstorms Thunderstorms form when moist, unstable air is lifted vertically into the atmosphere. Lifting of this air results in condensation and the release of latent heat . The process to initiate vertical lifting can be caused by: (1). Unequal warming of the surface of the Earth. Orographic lifting due to topographic obstruction of air flow. (3). Dynamic lifting because of the presence of a frontal zone Immediately after lifting begins, the rising parcel of warm moist air begins to cool because of adiabatic expansion. At a certain elevation the dew point is reached resulting in condensation and the formation of a cumulus cloud. For the cumulus cloud to form into a thunderstorm, continued uplift must occur in an unstable atmosphere. With the vertical extension of the air parcel, the cumulus cloud grows into a cumulonimbus cloud.

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. All thunderstorms are characterized by updrafts , rising air currents which supply the warm, humid air that fuels thunderstorms; sometimes, however, the column of rising air becomes a vortex a funnel cloud, or, if it reaches the ground, a tornado. 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.)

98. Tornadoes And Ball Lightning - Paper By Edward Lewis A Edward Lewis paper, with the discussion of ball lightning as plasmoids. http://www.padrak.com/ine/ELEWIS3.html

Return to the INE Main Page Tornadoes and Ball Lightning Edward Lewis P. O. Box 13050 Chicago, Illinois 60613 September 7, 1995; Revised July 22, 1996 and August 20, 1996 [Received via email to INE, June 1996. Revised Oct. 1996.] [Reposted Nov. 15, 1996.] 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).

THORNTON, Texas (CNN) At least five people were injured when tornadoes swept through central Texas Saturday evening, ripping roofs off homes and downing trees and power lines, officials said. The National Weather Service said at least three tornadoes hit the area south of Fort Worth, part of a fast-moving storm system that was already gone hours later. "The threat hasn't ended for the Gulf Coast states," said meteorologist Mike Vescio. "It's just winding down for North Texas." In the small town of Thornton, about 35 miles east of Waco, 20 homes were totaled and other farm-related structures were destroyed, said Limestone County Sheriff Dennis D. Wilson. The twister took down six towers of a high-line power line, causing at least $1 million in damage and knocking out power to a number of homes, he said. Elsewhere, tractors and cattle trailers were turned over, he said.
