The largest and most damaging tornadoes occur from Supercells, which are thunderstorms characterized by a mesocyclone: a vortex of rapidly rotating air that has a persistent updraft. Since high frequencies of in-cloud lightning can be a warning sign a tornado has formed or could form, meteorologists and everyday users who rely on total lightning detection systems can keep an eye on in-cloud lightning frequencies to help predict. Tornadoes that originate from a supercell thunderstorm are usually the strongest and most significant types of tornadoes. If you have ever seen the movie Twister, you will surely remember Dorothy and DOT3 which were the sensor packs used to place in front of a tornado. Forecasters and city planners may need to pay closer attention to these "transition zones" to better understand tornado risks, said Olivia Kellner, doctoral student in the Department of Earth, Atmospheric and Planetary Sciences and first author of the study. The NWS website lists a tornado observed and photographed by a hiker at 12,000 feet in Sequoia National Park, California, on July 7, 2004, as the likely candidate for highest elevation tornado known.
