Tornado Outbreak Of December 12–15, 2022
A four-day tornado outbreak affected the Central and Southern United States in mid-December 2022. The outbreak produced strong tornadoes in Oklahoma, Texas, Louisiana, Mississippi, and Georgia, resulting in severe damage and three fatalities. On December 13, a high-end EF1 tornado was caught on video from multiple angles as it caused considerable damage in Grapevine, Texas, where five people were injured, and multiple EF2 tornadoes caused significant damage in other parts of Texas and Oklahoma that morning. Two large EF2 tornadoes occurred near DeBerry, Texas and Keachi, Louisiana to the southwest of Shreveport, Louisiana, with the second one causing severe damage and two fatalities. An EF3 tornado struck the northern fringes of Farmerville, causing major structural damage and 14 injuries. Multiple strong tornadoes occurred across parts of the Gulf Coast region on December 14, and another fatality was confirmed in St. Charles Parish, Louisiana as a result of an EF2 tornado t ...

Tornado Outbreak
__NOTOC__ A tornado outbreak is the occurrence of multiple tornadoes spawned by the same 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 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 United States, and the Southeastern ...

Shreveport, Louisiana
Shreveport ( ) is a city in the U.S. state of Louisiana. It is the third most populous city in Louisiana after New Orleans and Baton Rouge, respectively. The Shreveport–Bossier City metropolitan area, with a population of 393,406 in 2020, is the fourth largest in Louisiana, though 2020 census estimates placed its population at 397,590. The bulk of Shreveport is in Caddo Parish, of which it is the parish seat. It extends along the west bank of the Red River (most notably at Wright Island, the Charles and Marie Hamel Memorial Park, and Bagley Island) into neighboring Bossier Parish. The United States Census Bureau's 2020 census tabulation for the city's population was 187,593, though the American Community Survey's census estimates determined 189,890 residents. Shreveport was founded in 1836 by the Shreve Town Company, a corporation established to develop a town at the juncture of the newly navigable Red River and the Texas Trail, an overland route into the newly independent R ...

Wind Shear
Wind shear (or 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 the control of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dallas–Fort Worth Metroplex
The Dallas–Fort Worth metroplex, officially designated Dallas–Fort Worth–Arlington by the U.S. Office of Management and Budget, is a conurbated metropolitan statistical area in the U.S. state of Texas encompassing 11 counties and anchored by the major cities of Dallas and Fort Worth. It is the economic and cultural hub of North Texas. Residents of the area also refer to it as DFW (airport code), or the Metroplex.

South Plains
The South Plains is a region in northwest Texas, consisting of 24 counties. The main crop is cotton. Counties The South Plains region includes 24 counties: The northernmost four (Parmer, Castro, Swisher, and Briscoe) are also considered to be part of the Texas Panhandle region. The region consists of a portion of the Texas side of the geographical Llano Estacado and the western portion of the lower part of the Southwestern Tablelands ecological region. South Plains extends south of the Texas Panhandle, centered at Lubbock. While prominent in the area of petroleum production, the South Plains is mainly an agricultural region, producing a great percentage of the nation's cotton and possessing numerous large cattle ranches. The South Plains is also home to several colleges and universities, the largest being Texas Tech University in Lubbock. Major cities and towns Cotton Cotton is the most common crop grown in South Plains region. In 2004 and again in 2005, records were broke ...

Enhanced Fujita Scale
The Enhanced Fujita scale (abbreviated as EF-Scale) rates tornado intensity based on the severity of the damage they cause. It is used in some countries, including the United States, Canada, China, and Mongolia. The Enhanced Fujita scale replaced the decommissioned Fujita scale that was introduced in 1971 by Ted Fujita. Operational use began in the United States on February 1, 2007, followed by Canada on April 1, 2013. It has also been proposed for use in France. The scale has the same basic design as the original Fujita scale—six intensity categories from zero to five, representing increasing degrees of damage. It was revised to reflect better examinations of tornado damage surveys, in order to align wind speeds more closely with associated storm damage. Better standardizing and elucidating what was previously subjective and ambiguous, it also adds more types of structures and vegetation, expands degrees of damage, and better accounts for variables such as differences in con ...

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 State ...

Storm Prediction Center Severe Weather Outlook For December 14, 2022
A storm is any disturbed state of the natural environment or the atmosphere of an astronomical body. It may be marked by significant disruptions to normal conditions such as strong wind, tornadoes, hail, thunder and lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain (ice storm), strong winds (tropical cyclone, windstorm), wind transporting some substance through the atmosphere such as in a dust storm, among other forms of severe weather. Storms have the potential to harm lives and property via storm surge, heavy rain or snow causing flooding or road impassibility, lightning, wildfires, and vertical and horizontal wind shear. Systems with significant rainfall and duration help alleviate drought in places they move through. Heavy snowfall can allow special recreational activities to take place which would not be possible otherwise, such as skiing and snowmobiling. The English word comes from Proto-Germanic ''*sturmaz'' meaning "noise, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tornadoes Of 2021
This page documents notable tornadoes and tornado outbreaks worldwide in 2021. Strong and destructive tornadoes form most frequently in the United States, Argentina, Brazil, Bangladesh, and Eastern India, but 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, Argentina, Australia and New Zealand.

December 2021 Midwest Derecho And Tornado Outbreak
On December 15, a rapidly-deepening low-pressure area contributed to a historic expanse of inclement weather across the Great Plains and Midwestern United States, resulting in an unprecedented December derecho and tornado outbreak across portions of the Northern United States, a region normally affected by snow and cold weather during this time of year. Non-thunderstorm winds spurred the formation of rapidly-moving fires across Colorado and western Kansas, with attendant dust and debris spreading eastward. From central Kansas northeastward into eastern Wisconsin, the powerful derecho led to hundreds of damaging wind reports. At least 57 hurricane-force wind reports were received by the National Weather Service, signaling the most prolific wind event in the United States dating back to at least 2004. Numerous embedded circulations within this rapidly-progressing derecho produced dozens of tornadoes, including 33 that were rated EF2. The culmination of non-thunderstorm, th ...

Tornado Outbreak Of March 21–23, 2022
A large tornado outbreak struck the Southern region of the United States on March 21–22, 2022, before transitioning to the Eastern United States on March 23. The outbreak started with numerous supercell thunderstorms and severe squall lines developing in central Texas and southern Oklahoma, prompting the issuance of numerous tornado warnings, including multiple PDS tornado warnings. An EF3 tornado caused considerable damage in Jacksboro, Texas while an EF2 tornado from the same storm caused a fatality in Sherwood Shores. Other strong tornadoes caused damage near College Station and in the Austin and Houston metropolitan areas. Severe and tornadic activity continued into the next day as the system moved eastward with numerous tornadoes reported in Mississippi and Alabama. On the evening of March 22, a supercell moved through the New Orleans metropolitan area, with an EF3 tornado producing severe damage in Arabi, resulting in one death and at least two injuries.
