Supercell thunderstorms are terrifying, natural marvels that carry high risks of lethality and devastation.

Common in America, supercell thunderstorms are much more severe.
Elston received his PhD from the University of Colorado Boulder in 2011, developing a system and algorithms for UAS sampling of tornadic supercell thunderstorms. This work culminated in the design of a UAS used to conduct the first-ever intercept of a tornadic supercell thunderstorm by an unmanned aircraft as part of the NSF and NOAA funded VORTEX2 project.
Giammanco's paper, "Observations of Hailstone Characteristics in Multi-cell and Supercell Thunderstorms," details the data collected during hail field research studies IBHS conducted in 2012 and 2013, which show that the hardness property of hailstones can be quantified through in-situ measurements.
Tornadoes that form from supercell thunderstorms are the most
TWISTEX has been collecting observations in and near tornadoes associated with supercell thunderstorms for six years.
Two ingredients are necessary to form the supercell thunderstorms that spawn tornadoes: A source of buoyant energy, namely warm and moist air near the ground, and a rotational force generated by winds at the surface blowing at a different speed or direction than winds high in the atmosphere.
A highly unstable air mass that developed on April 13 led to a large number of hailstorms in a relatively small region, and several supercell thunderstorms formed and produced large hailswaths across portions of Illinois, Indiana, Iowa, and Wisconsin during a 30-hour period.
