Tornadoes are ‘small-scale circulations’ which most often form in association with severe thunderstorms. They can cause great destruction on the ground, but they have limited lifespans of around 10 minutes and travel short distances. Tennessee Event Report: EF1 Tornado (Report).

One of the most extensive tornado outbreaks on record was the 1974 Super Outbreak, which affected a large area of the central United States and extreme southern Ontario on April 3 and 4, 1974. The outbreak featured 148 tornadoes in 18 hours, many of which were violent; six were of F5 intensity, and twenty-four peaked at F4 strength. Sixteen tornadoes were on the ground at the same time during its peak. More than 300people, possibly as many as 330, were killed. [116] See section on this tornado – This was a satellite tornado to the EF3 Bowling Green tornado above. [68]

Tornadoes occur most frequently in North America (particularly in central and southeastern regions of the United States colloquially known as Tornado Alley; the United States and Canada have by far the most tornadoes of any countries in the world). [7] Tornadoes also occur in South Africa, much of Europe (except Spain, most of the Alps, Balkans, and northern Scandinavia), western and eastern Australia, New Zealand, Bangladesh and adjacent eastern India, Japan, the Philippines, and southeastern South America (Uruguay and Argentina). [8] [9] Tornadoes can be detected before or as they occur through the use of pulse-Doppler radar by recognizing patterns in velocity and reflectivity data, such as hook echoes or debris balls, as well as through the efforts of storm spotters. [ citation needed] Tornado rating scales For comparison, the Fujita scale of tornado intensity goes as high as F5, which is applied to any tornado that brings in winds of 261–318 mph and causes “incredible damage”. In Indiana, damage was mostly limited to power outages from the storms and trees falling into houses and onto vehicles, with only one person being hospitalized. [206] [207] At least 17,000 Duke Energy customers, 12,500 AES Indiana customers, 12,500 Indiana Michigan Power Co. customers, [208] and 1,300 South Central Indiana REMC customers lost power due to the storms. [209] This strong tornado was spawned by an embedded supercell within a QLCS complex moving through central and eastern Arkansas. Numerous homes, mobile homes, and businesses were damaged or destroyed in Trumann, with the most intense damage occurring in the northeastern part of town. A small vacant grocery store building was completely destroyed. The Trumann fire department building had its roof torn off, and a nursing home was significantly damaged, though no injuries occurred there, as the building had been evacuated prior to the tornado. Many large trees were snapped or uprooted throughout the town, and an RV camper was overturned as well. [56]Apartment buildings were damaged in Diaz, as were structures at a nearby park. Several trees were also uprooted. [42] Evan Beebe (December 11, 2021). "3 deaths confirmed following tornadoes in northwest Tennessee". WPSD-TV. Archived from the original on December 11, 2021 .

A house and a tobacco barn sustained major roof damage, a second house sustained minor roof and gutter damage, and several trees were downed. [90] The initial winter storm, unofficially referred to by The Weather Channel (TWC) as Winter Storm Atticus, [171] [172] entered the Western United States on December 9. The storm brought the first measurable snowfall of the rainy season to Utah. In southern Wyoming and Colorado, the storm dropped a maximum total of 3 feet (0.91m) of snow in the mountains. [1] The storm led to Denver seeing 0.3 inches (0.76cm), which became their first snowfall of the winter, the latest date on record for this occurrence. [173] On December 10, Las Vegas dipped to 32°F (0°C) for the first time since February 5, 2020. [174] Missouri Event Report: EF2 Tornado (Report). National Centers for Environmental Information.

Some evidence does suggest that the Southern Oscillation is weakly correlated with changes in tornado activity, which vary by season and region, as well as whether the ENSO phase is that of El Niño or La Niña. [99] Research has found that fewer tornadoes and hailstorms occur in winter and spring in the U.S. central and southern plains during El Niño, and more occur during La Niña, than in years when temperatures in the Pacific are relatively stable. Ocean conditions could be used to forecast extreme spring storm events several months in advance. [100] Tennessee Event Report: EF2 Tornado (Report). National Centers for Environmental Information.

Unlike audible signatures, tornadic signatures have been isolated; due to the long-distance propagation of low-frequency sound, efforts are ongoing to develop tornado prediction and detection devices with additional value in understanding tornado morphology, dynamics, and creation. [47] Tornadoes also produce a detectable seismic signature, and research continues on isolating it and understanding the process.
