2021Central U.S. Tornado Outbreak - ArcGIS StoryMaps
Dec 15, 2021 · On the night of December 10- 11, 2021, a string powerful tornadoes ripped through parts of the Midwest and South U.S. More than 30 tornadoes swept through six states (Kentucky, Illinois, Tennessee, Mississippi, Missouri, and Arkansas) killing at least 70 people, displacing thousands, and wrecking towns over hundreds of miles.

Mar 1, 2016 · Typical springtime tornado outbreaks in the United States (e.g., Carr 1952; Fujita et al. 1970; Galway 1975, 1977; Grazulis 1993) are associated with several synoptic features: extratropical cyclones (ECs), frontal systems, and upper-level troughs together with their associated jet stream.
Entraining CAPE for Better Assessment of Tornado Outbreak
Mar 1, 2019 · Our composite analysis of extratropical cyclones that caused tornado outbreaks (OCs) and those that did not (NOCs) has shown that CAPE including the effects of entrainment of environmental air (E-CAPE) is more useful in examining the differences between OCs from NOCs than is traditional CAPE.
List of North American tornadoes and tornado outbreaks - Wikipedia
These are some notable tornadoes, tornado outbreaks, and tornado outbreak sequences that have occurred in North America. The listing is U.S.-centric, with greater and more consistent information available for U.S. tornadoes.
tornado outbreaks remain poorly understood. In the present study, we use composite analyses of reanalysis data between April and May from 1995 to 2012 in the United States to investigate differences in the structure and environment between ECs that cause tornado outbreaks and those that do not, and we con-

Feb 16, 2016 · AbstractThe structural and environmental characteristics of extratropical cyclones that cause tornado outbreaks [outbreak cyclones (OCs)] and that do not [nonoutbreak cyclones (NOCs)] are examined using the Japanese 55-year Reanalysis dataset (JRA-55).

AbstractTo clarify the effects of the horizontal shear of the jet stream on the structure and environment of extratropical cyclones that are accompanied by tornado outbreaks (OCs) and those that are not (NOCs), two idealized numerical experiments are performed.
