Elston received his PhD from the University of Colorado Boulder in 2011, developing a system and algorithms for UAS sampling of tornadic supercell thunderstorms
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
Several supercell thunderstorms
developed to my northwest later in the afternoon, all lined up in a row and headed my way.
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.
WORCESTER - About 75 weather enthusiasts got the lowdown on squall lines, shelf clouds, wall clouds and supercell thunderstorms
