A satellite tornado is a tornado that revolves around a larger, primary tornado and interacts with the same mesocyclone. Satellite tornadoes occur apart from the primary tornado and are not considered subvortices; the primary tornado and satellite tornadoes are considered to be separate tornadoes. The cause of satellite tornadoes is not known. Such tornadoes are more often anticyclonic than are typical tornadoes and these pairs may be referred to as tornado couplets. [1] Satellite tornadoes commonly occur in association with very powerful, large, and destructive tornadoes, indicative also of the strength and severity of the parent supercell thunderstorm. [2]

Contents

Satellite tornadoes are relatively uncommon. When a satellite tornado does occur, there is often more than one orbiting satellite spawned during the life cycle of the tornado or with successive primary tornadoes spawned by the parent supercell (a process known as cyclic tornadogenesis and leading to a tornado family). On tornado outbreak days, if satellite tornadoes occur with one supercell, there is an elevated probability of their occurrence with other supercells.[ citation needed ]

Satellite tornadoes may merge into their companion tornado although the appearance of this occurring is often an illusion caused when an orbiting tornado revolves around the backside of a primary tornado obscuring view of the satellite. [3] During the March 1990 Central United States tornado outbreak, one member of a tornado family (rated F5) constricted and became a satellite tornado of the next tornado of the family before merging into the new primary tornado which soon also intensified to F5. [4]

Examples

Some examples of tornado couplets include the Tri-State Tornado, [5] multiple tornadoes during the 1999 Oklahoma tornado outbreak, [6] the 2007 Greensburg tornado, [7] and the 2013 El Reno tornado. [8] Satellite tornadoes are more likely to be recognized in recent decades than in the far past as eyewitness accounts as well as damage survey information are often available for later events. The advent of storm chasing, in particular, boosts the likelihood that satellite tornadoes are noticed visually and/or on mobile radar. [9] These tornadoes may remain over open country and thus cause less structural damage and consequently are less widely known. Such examples include near Beloit, Kansas on 15 May 1990 and during Project VORTEX near Allison, Texas on 8 June 1995, among other events. [3]

<span class="mw-page-title-main">Tornado outbreak sequence of May 5–10, 2015</span>

The tornado outbreak sequence of May 5–10, 2015 was a six-day outbreak of tornado activity that affected the Great Plains of the United States in early May 2015. On May 6, strong tornadoes impacted the Oklahoma City area, along with rural parts of Kansas, Texas, Arkansas, South Dakota, and Nebraska. The outbreak coincided with major flooding, with large amounts of rain falling in parts of Nebraska, Kansas, Oklahoma, and Texas. The National Weather Service forecast office in Norman, Oklahoma issued a "flash flood emergency" for Oklahoma City following record-breaking rainfall that occurred in the area that evening. The outbreak sequence resulted in five tornado-related deaths, along with two flood-related deaths. A total of 127 tornadoes were confirmed and rated as a result of this outbreak sequence. Damage from the outbreak was estimated at $1.5 billion.

<span class="mw-page-title-main">2015 Texas–Oklahoma flood and tornado outbreak</span> Wind and rainstorm in the south-central United States and Mexico

Preceded by more than a week of heavy rain, a slow-moving storm system dropped tremendous precipitation across much of Texas and Oklahoma during the nights of May 24–26, 2015, triggering record-breaking floods. Additionally, many areas reported tornado activity and lightning. Particularly hard hit were areas along the Blanco River in Hays County, Texas, where entire blocks of homes were leveled. On the morning of May 26, the National Weather Service issued a flash flood emergency for southwest Harris County and northeast Fort Bend County. The system also produced deadly tornadoes in parts of Mexico, Texas, and Oklahoma. This flood significantly contributed to the wettest month ever for Texas and Oklahoma.

<span class="mw-page-title-main">Tornado outbreak of November 16–18, 2015</span> 2015 tornado outbreak in Kansas and Texas

The Tornado outbreak of November 16–18, 2015 was a highly unusual nocturnal late-season tornado outbreak that significantly impacted the lower Great Plains on November 16 before producing additional weaker tornadoes across parts of the Southern United States the following two days. The first day of the outbreak spawned multiple strong, long-track tornadoes, including two consecutive EF3s that caused major damage near Pampa, Texas. Overall, the outbreak produced 61 tornadoes in all, and was described as by the National Weather Service office in Dodge City, Kansas as being "unprecedented in recorded history for southwest Kansas" given the magnitude and the late season. In addition, the tornado outbreak brought the first November tornadoes into northwest Kansas, and the first strong tornadoes in the Texas Panhandle in November, as well as the further west any F3/EF3 tornadoes touched down this late in the calendar year. Despite spawning multiple strong tornadoes after dark, no fatalities and only one minor injury occurred as a result of the outbreak.

<span class="mw-page-title-main">Tornado outbreak of February 28 – March 1, 2017</span>

The tornado outbreak of February 28 – March 1, 2017 was a widespread and significant outbreak of tornadoes and severe weather that affected the Midwestern United States at the end of February 2017 and beginning of March. Fueled by the combination of ample instability, strong wind shear, and rich low-level moisture, the event led to 71 confirmed tornadoes and thousands of other non-tornadic severe weather reports. The most notable aspect of the outbreak was a long-tracked EF4 tornado—the first violent tornado of 2017 and the first violent tornado during the month of February since the 2013 Hattiesburg, Mississippi tornado—that tracked from Perryville, Missouri to near Christopher, Illinois, killing one person. Three EF3 tornadoes were recorded during the event, including one that caused two fatalities in Ottawa, Illinois, one that caused a fatality near Crossville, and one that heavily damaged or destroyed homes in and around Washburn. In addition to the deaths, 38 people were injured by tornadoes and an additional 30 were injured by non-tornadic impacts, mainly by fallen trees.

A prolonged period of intense tornado activity affected the Great Plains, Great Lakes, and Ohio Valley during May 15–20, 2017. This outbreak sequence was the most prolific tornado event of 2017 in terms of number of tornadoes. It is also notable for producing the longest-tracked tornado in Wisconsin state history: an intense EF3 tornado that remained on the ground for over 82 miles (132 km) and killed one person while causing major damage near Chetek and Conrath. Overall, the outbreak sequence resulted in two deaths and several injuries.

This page documents notable tornadoes and tornado outbreaks worldwide in 2018. Strong and destructive tornadoes form most frequently in the United States, Brazil, Bangladesh 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, Argentina and Australia. Tornadic events are often accompanied with other forms of severe weather, including strong thunderstorms, strong winds, and hail.

<span class="mw-page-title-main">April 2018 North American storm complex</span>

The April 2018 North American storm complex brought a wide swath of severe and winter weather that affected much of Midwest across to the East Coast of the United States. This particular outbreak led to at least 73 confirmed tornadoes over a three-day period, most of which occurred across Arkansas and Louisiana during the evening hours of April 13. The most significant tornadoes were an EF1 that caused a fatality in Red Chute, Louisiana, early on April 14, an upper-end EF2 tornado that impacted eastern sections of Greensboro, North Carolina on April 15, causing 17 injuries, and a significant EF3 tornado that impacted areas from Lynchburg to Elon, Virginia, causing severe damage and at least 10 injuries.

<span class="mw-page-title-main">Tornado outbreak of November 30 – December 2, 2018</span> Weather event in the central US

The tornado outbreak of November 30 – December 2, 2018 was a late-season tornado outbreak that occurred across portions of the West South Central states and Midwestern United States. As a potent shortwave trough moved across the southern portions of the country, it was met with ample moisture return and destabilization, resulting in widespread severe thunderstorms that produced damaging winds, hail, and tornadoes. The event began late on November 30 in Oklahoma, spreading east and resulting in one fatality in Aurora, Missouri. Several tornadic supercells moved across portions of Illinois on December 1, and resulted in 29 confirmed tornadoes. This outbreak was the largest December tornado event on record in Illinois history, surpassing the December 1957 tornado outbreak sequence. The most significant tornado of the event was an EF3 that impacted Taylorville, Illinois, damaging or destroying hundreds of structures and injuring 22 people.

<span class="mw-page-title-main">Tornado outbreak of March 3, 2019</span> Severe weather effect in the Southeastern United States

A significant and deadly severe weather event that affected the Southeastern United States on March 3, 2019. Over the course of 6 hours, a total of 41 tornadoes touched down across portions of Alabama, Georgia, Florida, and South Carolina. The strongest of these was an EF4 tornado that devastated rural communities from Beauregard, Alabama, through Smiths Station, Alabama to Talbotton, Georgia, killing 23 people and injuring at least 100 others. Its death toll represented more than twice the number of tornado deaths in the United States in 2018 as well as the deadliest single tornado in the country since the 2013 Moore EF5 tornado. An EF3 tornado also destroyed residences to the east of Tallahassee in Leon County, Florida, and was only the second tornado of that strength in the county since 1945. Several other strong tornadoes occurred across the region throughout the evening of March 3 and caused significant damage. A large number of EF0 and EF1 tornadoes also touched down.

<span class="mw-page-title-main">Tornado outbreak of April 21–23, 2020</span>

On April 22, 2020, an outbreak of discrete supercell thunderstorms across portions of Oklahoma, Texas, and Louisiana led to widespread severe weather, including multiple strong tornadoes. Two people were killed by a high-end EF2 that struck the town of Madill, Oklahoma, and three more were killed by an EF3 wedge tornado that moved through Onalaska, Texas. Dozens of others were injured as well. The event came to fruition as a trough progressed eastward across the United States, interacting with a moist and unstable environment. Tornado activity continued into Arkansas, Louisiana, Mississippi, Alabama, Florida, and Georgia overnight into the day on April 23. Isolated tornado activity also occurred during the overnight hours on April 21.

A significant tornado outbreak sequence took place from March 24–28, 2021 in the Southern United States just one week after another outbreak affected similar regions. There were 43 tornadoes confirmed across 11 states, with the bulk of activity primarily on March 25, which resulted in the Storm Prediction Center (SPC) issuing its second high-risk outlook for the month of March, as well as the second high-risk outlook for 2021. Several intense tornadoes touched down on that day, including ones that prompted the issuance of rare tornado emergencies near Hoover, Alabama, Brent and Centreville, Alabama, and in the Newnan, Georgia area. March 27 also saw widespread tornado activity mainly across East Texas, Southern Arkansas, Louisiana, and Western Tennessee with several strong tornadoes touching down. Scattered to widespread wind and hail damage occurred throughout the outbreak sequence, and repeated rounds of heavy rain caused widespread severe flash and river flooding across much of Tennessee.

<span class="mw-page-title-main">Hurricane Ida tornado outbreak</span> 2021 tornado outbreak

Hurricane Ida generated a tornado outbreak as it traversed the Southeastern, Mid-Atlantic, and Northeastern United States. Thirty-five confirmed tornadoes touched down from Mississippi to Massachusetts; one person was killed in Upper Dublin Township, Pennsylvania, and several people were injured in Alabama, New Jersey, and Pennsylvania. The most active and destructive part of the outbreak occurred during the afternoon of September 1, when several strong tornadoes struck Maryland, New Jersey, and Pennsylvania, including an EF3 tornado which impacted Mullica Hill, New Jersey. The same storm later dropped an EF1 tornado that prompted a tornado emergency for Burlington, New Jersey and Croydon, and Bristol, Pennsylvania, the first of its kind in the Northeast, as well as the first such alert associated with a tropical cyclone or it's remnants. This outbreak severely impacted New Jersey and the Philadelphia Metropolitan Area, a region which had been significantly impacted by strong tornadoes from another outbreak that occurred just over a month prior, as well as several weak tornadoes from the remnants of Tropical Storm Fred two weeks earlier.
