TWISTEX
Tactical Weather Instrumented Sampling in/near Tornadoes EXperiment
Founded by engineer Tim Samaras to deploy his HITPR "turtle" probes and mesonet vehicles directly in tornadoes' paths, combining hard engineering with field science rather than theory alone.
Founder
Tim Samaras
Signature Moment
100-millibar pressure drop, Manchester, SD, 2003
Legacy
Samaras, his son Paul, and teammate Carl Young were killed in the record-width El Reno, OK tornado on May 31, 2013 — reshaping storm-chasing safety norms industry-wide.

Tornado Intercept Vehicle (TIV1/TIV2), IMAX films Tornado Alley & Forces of Nature, Discovery's Storm Chasers
Reed Timmer
Meteorologist, "extreme" storm chaser
