Debris Fallout
Debris fallout refers to debris lofted into the air by a tornado that falls back to the ground, and that can persist well after a tornado has lifted. Debris lofted by stronger tornadoes has been known to travel significant distances, upwards of on rare occasions. Debris fallout events can be detected on radar using dual polarization products, notably correlation coefficient. Most debris in excess of is not moved a great distance; however, lighter objects—especially paper goods—can be absorbed by the storm's updraft and moved into its Supercell#Forward-flank downdraft (FFD), forward-flank downdraft where they can be transported further by non-tornadic downdraft winds. Mechanism The basic mechanism of debris fallout is debris lofted by a tornado's updraft winds high into the atmosphere. Charles E. Anderson completed the first study focusing on debris fallout on the F5 Tornado outbreak of June 7–8, 1984#Barneveld–Black Earth, Wisconsin, 1984 Barneveld tornado, which produc ...

Tornadic Debris Lofted Over 30,000 Feet
A tornado is a violently rotating column of air that is in contact with the surface of Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is often referred to as a twister, whirlwind or cyclone, although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the Earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Tornadoes come in many shapes and sizes, and they are often (but not always) visible in the form of a funnel cloud, condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than , are about across, and travel several kilometers (a few miles) before dissipating. The Tornado records#Highest winds observed in a tornado, most extreme tornadoes can attain wind speeds of mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2011 Super Outbreak
The 2011 Super Outbreak was the largest, costliest, and one of the deadliest tornado outbreaks ever recorded, taking place in the Southern, Midwestern, and Northeastern United States from April 25 to 28, 2011, leaving catastrophic destruction in its wake. Over 175 tornadoes struck Alabama, Mississippi, and Tennessee, which were the most severely damaged states. Other destructive tornadoes occurred in Arkansas, Georgia, Kentucky, Louisiana, New York, and Virginia, with storms also affecting other states in the Southern and Eastern United States. In total, 368 tornadoes were confirmed by NOAA's National Weather Service (NWS) and Government of Canada's Environment Canada in 21 states from Texas to New York to southern Canada. Widespread and destructive tornadoes occurred on each day of the outbreak. April 27 was the most active day, with a record 224 tornadoes touching down that day from midnight to midnight CDT (05:00–05:00 UTC). Four of the tornadoes were rated EF5, wh ...
