Evansville Tornado Of November 2005
A destructive outbreak of nine tornadoes struck the Mississippi Valley and the Midwest during the overnight hours of November 5–6, 2005. The worst event was an F3 tornado that formed early in the morning of November 6, 2005, outside of Evansville, Indiana, United States. It was the first of several tornado events that November. The tornado resulted in 24 confirmed fatalities across the region, making it the deadliest and most destructive November tornado in Indiana's history. Meteorological analysis The system formed on a warm front that tracked across the Midwestern United States, Midwest and stretched from the northern Great Lakes to Tennessee. The front was enhanced by a strong jet stream and warm, humid air ahead of it, allowing thunderstorms to develop. A severe thunderstorm watch was issued for the region just west of Evansville as the main threat appeared to be straight-line winds. The system had formed into a squall line but at about 1:30 am CST (0730 UTC), the squall lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tornadoes Of 2005
This page documents notable tornadoes and tornado outbreaks worldwide in 2005. Strong and destructive tornadoes form most frequently in the United States, Bangladesh, Argentina, Brazil and Eastern India, but they can occur almost anywhere under the right conditions. Tornadoes also develop occasionally in southern Canada during the Northern Hemisphere's summer and somewhat regularly at other times of the year across Europe, Asia, and Australia. Tornadic events are often accompanied with other forms of severe weather, including strong thunderstorms, strong winds, and hail. Synopsis The first half of 2005 was fairly slow when it comes to tornadoes. There were no major outbreaks in the first half of 2005, which is rather unusual. The inactivity in what is normally the peak months can be related to a stable low-pressure system that blocked the parade of storms from moving eastward. The third quarter of 2005 was dominated by the tropics, and many of the tornadoes were related to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Civil War Battle of Clark's Mill took place near Vera Cruz on November 7, 1862, and resulted in a Confederate victory. After the American Civil War, during a period of general chaos, a group from the western part of the county broke into the Arno courthouse and removed the records back to Vera Cruz. Later in 1871, a new town site was selected, present-day Ava, near the location of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fujita Scale
The Fujita scale (F-Scale; ), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation. The official Fujita scale category is determined by meteorologists and engineers after a ground or aerial damage survey, or both; and depending on the circumstances, ground-swirl patterns ( cycloidal marks), weather radar data, witness testimonies, media reports and damage imagery, as well as photogrammetry or videogrammetry if motion picture recording is available. The Fujita scale was replaced with the Enhanced Fujita scale (EF-Scale) in the United States in February 2007. In April 2013, Canada adopted the EF-Scale over the Fujita scale along with 31 "Specific Damage Indicators" used by Environment Canada (EC) in their ratings. Background The scale was introduced in 1971 by Ted Fujita of the University of Chicago, in collaboration with Allen Pearson, head of the Nationa ...

Supercell
A supercell is a thunderstorm characterized by the presence of a mesocyclone: a deep, persistently rotating updraft. Due to this, these storms are sometimes referred to as rotating thunderstorms. Of the four classifications of thunderstorms (supercell, squall line, multi-cell, and single-cell), supercells are the overall least common and have the potential to be the most severe. Supercells are often isolated from other thunderstorms, and can dominate the local weather up to away. They tend to last 2–4 hours. Supercells are often put into three classification types: classic (Normal precipitation level), low-precipitation (LP), and high-precipitation (HP). LP supercells are usually found in climates that are more arid, such as the high plains of the United States, and HP supercells are most often found in moist climates. Supercells can occur anywhere in the world under the right pre-existing weather conditions, but they are most common in the Great Plains of the United Stat ...

Ohio Valley
The Ohio River is a long river in the United States. It is located at the boundary of the Midwestern and Southern United States, flowing southwesterly from western Pennsylvania to its mouth on the Mississippi River at the southern tip of Illinois. It is the third largest river by discharge volume in the United States and the largest tributary by volume of the north-south flowing Mississippi River that divides the eastern from western United States. It is also the 6th oldest river on the North American continent. The river flows through or along the border of six states, and its drainage basin includes parts of 14 states. Through its largest tributary, the Tennessee River, the basin includes several states of the southeastern U.S. It is the source of drinking water for five million people. The lower Ohio River just below Louisville is obstructed by rapids known as the Falls of the Ohio where the elevation falls in restricting larger commercial navigation, although in the 1 ...

Squall Line
A squall line, or more accurately a quasi-linear convective system (QLCS), is a line of thunderstorms, often forming along or ahead of a cold front. In the early 20th century, the term was used as a synonym for cold front (which often are accompanied by abrupt and gusty wind shifts). Linear thunderstorm structures often contain heavy precipitation, hail, frequent lightning, strong straight-line winds, and occasionally tornadoes or waterspouts. Particularly strong straight-line winds can occur where the linear structure forms into the shape of a bow echo. Tornadoes can occur along waves within a line echo wave pattern (LEWP), where mesoscale low-pressure areas are present. Some bow echoes can grow to become derechos as they move swiftly across a large area. On the back edge of the rainband associated with mature squall lines, a wake low can be present, on very rare occasions associated with a heat burst. Theory Polar front theory was developed by Jacob Bjerknes, derived from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storm Prediction Center
The Storm Prediction Center (SPC) is a US government agency that is part of the National Centers for Environmental Prediction (NCEP), operating under the control of the National Weather Service (NWS), which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the United States Department of Commerce (DoC). Headquartered at the National Weather Center in Norman, Oklahoma, the Storm Prediction Center is tasked with forecasting the risk of severe thunderstorms and tornadoes in the contiguous United States. It issues convective outlooks, mesoscale discussions, and watches as a part of this process. Convective outlooks are issued for the following eight days (issued separately for Day 1, Day 2, Day 3, and Days 4–8), and detail the risk of severe thunderstorms and tornadoes during the given forecast period, although tornado, hail and wind details are only available for Days 1 and 2. Day 3, as well as 4–8 use a probabilistic scale, dete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
