=== Supercell relationship ===
{{See also|Supercell}}
Tornadoes often develop from a class of thunderstorms known as supercells. Supercells contain [[mesocyclone]]s, an area of organized rotation a few kilometers/miles up in the atmosphere, usually {{convert|1|–|6|mi|km|abbr=in|order=flip}} across. Most intense tornadoes (EF3 to EF5 on the [[Enhanced Fujita Scale]]) develop from supercells. In addition to tornadoes, very heavy rain, frequent lightning, strong wind gusts, and hail are common in such storms.<ref>{{Cite web |title=Radar Signatures for Severe Convective Weather: Low-Level Mesocyclone, Print Version |url=http://www.faculty.luther.edu/~bernatzr/Courses/Sci123/comet/radar/severe_signatures/print_low_level_meso.htm |access-date=2022-06-03 |website=www.faculty.luther.edu}}</ref><ref>{{Cite web |last=US Department of Commerce |first=NOAA |title=Supercell Structure and Dynamics |url=https://www.weather.gov/lmk/supercell/dynamics |access-date=2022-06-03 |website=www.weather.gov |language=EN-US |archive-date=2022-05-26 |archive-url=https://web.archive.org/web/20220526012804/https://www.weather.gov/lmk/supercell/dynamics |url-status=live }}</ref>

Most tornadoes from supercells follow a recognizable life cycle which begins when increasing rainfall drags with it an area of quickly descending air known as the [[rear flank downdraft]] (RFD). This downdraft accelerates as it approaches the ground, and drags the supercell's rotating mesocyclone towards the ground with it.<ref name="Advanced Spotter Guide" />
