Uncommon card · No. 90321

TWISTEX (an acronym for Tactical Weather-Instrumented Sampling in/near Tornadoes EXperiment) were tornado research field experiments founded and led by Tim Samaras in 2007. The research objectives were to better understand tornado features, tornado maintenance, tornadogenesis and tornado longetivity using in-situ probes that gathered thermodynamic and kinematic datasets at close proximity to tornadoes, and mobile mesonet stations that were mounted on participating vehicles. The experiment originated in 2003 as Project ANSWERS (an acronym for Analysis of the Near-Surface Wind and Environment Along the Rear Flank of Supercells), a field experiment founded by Cathy Finley and Dr. Bruce Lee, with an objective of gathering Rear Flank Downdraft (RFD) datasets to determine its contribution towards mesocyclogenesis, tornadogenesis, and tornado maintenance. Project ANSWERS operated 4 years before founders Cathy and Bruce helped Tim Samaras to merge their work into TWISTEX in 2007. TWISTEX was one...
