2011 Ringgold–Apison Tornado
In the evening hours of April 27, 2011, a violent and long-tracked Multiple-vortex tornado, multi-vortex tornado impacted several communities along a path through northern Georgia (U.S. state), Georgia and southeast Tennessee, including Ringgold, Georgia, Apison, Tennessee and Cleveland, Tennessee. The tornado, which was on the ground for 52 minutes and became known as the Ringgold–Apison tornado or The Monster, killed over twenty people while having windspeeds that were estimated to have been as high as . The tornado was part of 2011 Super Outbreak, the largest outbreak of tornadoes in recorded history, and was the deadliest to hit Georgia during the outbreak. The tornado touched down in rural Catoosa County, Georgia near Rock Spring, Georgia, Rock Spring, where it slowly intensified and damaged trees before crossing Jackson Lake (Georgia), Jackson Lake and entering into Ringgold, where it damaged several commercial buildings and later residential homes. Nine people were killed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ringgold, Georgia
Ringgold is a city in and the county seat of Catoosa County, Georgia, United States. Its population was 3,414 at the 2020 census. It is part of the Chattanooga metropolitan area. History Ringgold was founded in 1846 and incorporated as a city in 1847. It was named after Samuel Ringgold, a hero of the Battle of Palo Alto in the Mexican–American War. Ringgold is where ''The General'' locomotive stopped during the Great Locomotive Chase on April 12, 1862. Ringgold is also home to the historic Ringgold Depot, which still contains bullet marks from the Civil War. The Battle of Ringgold Gap took place on November 27, 1863. Confederate Major General Patrick Cleburne with 4,100 men used the mountain pass known as the Ringgold Gap to stall the advance of Union Major General Joseph Hooker and his troops. Hooker's troops were over 12,000 strong. It was a Confederate victory because it allowed Confederate artillery and wagon trains to move safely through the Ringgold Gap unharmed whi ...

Jackson Lake (Georgia)
Jackson Lake is one of the oldest reservoirs in Georgia, United States, southeast of Atlanta in a rural area situated within parts of three counties (Jasper, Newton and Butts). The Lloyd Shoals Dam was built in 1910 by Central Georgia Power Company, and electricity was originally generated for the city of Macon. Relative to others in the state, it is a smaller lake (about with of shoreline), which still generates electricity and provides a location for water sports, boating, wakeboarding and fishing. Jackson Lake is formed by the confluence of the Yellow, Alcovy and South rivers. Tussahaw Creek is also a significant tributary. Below the Lloyd Shoals Dam, the lake's outlet is the Ocmulgee River. Lloyd Shoals Dam In 1907, Jordan Massee, Sr. and associates bought the Macon Railway and Light Company from Jacob Collins of Savannah. After acquiring it, Masse became the president. When he was 35, he put together the Bibb Power Company. Soon after the Bibb Power Company was orga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesoscale Convective System
A mesoscale convective system (MCS) is a complex of thunderstorms that becomes organized on a scale larger than the individual thunderstorms but smaller than extratropical cyclones, and normally persists for several hours or more. A mesoscale convective system's overall cloud and precipitation pattern may be round or linear in shape, and include weather systems such as tropical cyclones, squall lines, lake-effect snow events, polar lows, and mesoscale convective complexes (MCCs), and generally forms near weather fronts. The type that forms during the warm season over land has been noted across North and South America, Europe, and Asia, with a maximum in activity noted during the late afternoon and evening hours. Forms of MCS that develop within the tropics use either the Intertropical Convergence Zone (ITCZ) or monsoon troughs as a focus for their development, generally within the warm season between spring and fall. One exception is that of lake-effect snow bands, which form due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1974 Super Outbreak
The 1974 Super Outbreak was one of the most intense tornado outbreaks on record, occurring on April 3–4, 1974, across much of the United States. It was one of the deadliest tornado outbreaks in U.S. history. It was also the most violent tornado outbreak ever recorded, with 30 Fujita scale, violent (F4 or F5 rated) tornadoes confirmed. From April 3–4, there were 148 tornadoes confirmed in 13 U.S. states and the Canadian province of Ontario. In the United States, the tornadoes struck Illinois, Indiana, Michigan, Ohio, Kentucky, Tennessee, Alabama, Mississippi, Georgia (U.S. state), Georgia, North Carolina, Virginia, West Virginia, and New York (state), New York. The outbreak caused roughly $600 million USD (equivalent to $ in ) in damage. The outbreak extensively damaged approximately along a total combined path length of . At one point, as many as 15 separate tornadoes were occurring simultaneously. The 1974 Super Outbreak was the first tornado outbreak in reco ...

Low-pressure Area
In meteorology, a low-pressure area (LPA), low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. It is the opposite of a high-pressure area. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies. Winds circle anti-clockwise around lows in the northern hemisphere, and clockwise in the southern hemisphere, due to opposing Coriolis forces. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere (aloft). The formation process of a low-pressure area is known as cyclogenesis. In meteorology, atmospheric divergence aloft occurs in two kinds of places: * The first is in the area on the east side of upper troughs, which form half of a Rossby wave within the Westerlies (a trough with large wavelength that extends through the troposphere). * A ...

Tornado Outbreak
A tornado outbreak is the occurrence of multiple tornadoes spawned by the same Synoptic scale meteorology, synoptic scale weather system. The number of tornadoes required to qualify as an outbreak typically are at least six to ten, with at least two rotational locations (if squall line) or at least two supercells producing Tornado family, multiple tornadoes. The tornadoes usually occur within the same day or continue into the early morning hours of the succeeding day, and within the same region. Most definitions allow for a break in tornado activity (time elapsed from the end of the last tornado to the beginning of the next tornado) of six hours. If tornado activity indeed resumes after such a lull, many definitions consider the event to be a new outbreak. A series of continuous or nearly continuous tornado outbreak days is a tornado outbreak sequence. In the United States and Canada, tornado outbreaks usually occur from March through June in the Great Plains, the Midwestern Unit ...

Wind Shear
Wind shear (; also written windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shortwave (meteorology)
A shortwave or shortwave trough is an embedded kink in the trough / ridge pattern. Its length scale is much smaller than that of and is embedded within longwaves, which are responsible for the largest scale (synoptic scale) weather systems. Shortwaves may be contained within or found ahead of longwaves and range from the mesoscale to the synoptic scale. Shortwaves are most frequently caused by either a cold pool or an upper level front. Shortwaves are commonly referred to as a vorticity maximum. Corresponding weather and effects Shortwaves are often associated with warm air advection (WAA) or cold air advection (CAA), which influence temperature. Due to the way they move the air around them and the way air moves away from them, shortwaves produce positive curvature vorticity and positive shear vorticity, respectively. Ahead of a shortwave there is large-scale lift due to divergence from positive vorticity advection (PVA). This lift often causes precipitation. In a capp ...
