Joplin, Missouri
Each June, Joplin hosts the Boomtown Run, a half marathon, 5K, and children's run. The event attracts runners from across the country, and features USTA certified courses which start and end in the historic downtown area. Celebrity runners featured at the prerace banquet have included Bart Yasso, Sarah Reinerston, Suzy Favor-Hamilton, and Jeff Galloway. In 2011, due to the devastating EF5 tornado that struck Joplin on May 22, just three weeks before the run, the event was transformed in the Boomtown Run Day of Service. About 270 individuals registered for the race after the tornado struck, knowing their proceeds would benefit tornado recovery. On June 11, about 270 registered runners and volunteers turned out to help clean debris and sort donations, contributing more than 1,200 hours of service. On August 7, 2012, the Village of Silver Creek and the City of Joplin voted to have Silver Creek annexed into Joplin City limits.
Tornadoes of 1973
Notable scientific milestones toward understanding the life cycle of tornadoes occurred in Oklahoma on May 24, 1973, when researchers exploited primitive Doppler weather radar, then under development by the National Severe Storms Laboratory (NSSL), to examine a tornado vortex signature, or TVS, for the first time in history. The scientists, in one of the earliest successful cases of storm chasing, were able to study the evolution of a violent tornado near Union City, and to generate clear visual photography of its entire life cycle, from birth to decay. The successful deployment of Doppler radar to detect tornado formation also pointed the way to the development of a nationwide Doppler radar system, and helped precipitate funding for studies on tornadogenesis.
At the beginning of the year, one of the strongest El Niño episodes since 1950, as defined by sea surface temperatures, was in progress but gradually diminishing, according to the Oceanic Niño Index (ONI). Peak trimonthly anomalies, measured in moving averages, were +1.7 °C above normal for the period December–February 1972 – 1973. The month of January featured clusters of tornado activity along the Gulf Coast, primarily in Texas and Louisiana, as well as part of the Florida peninsula—a pattern not inconsistent with that of El Niño winters in general. The deadliest and strongest tornado of the month was an F3 that struck Caldwell Parish, Louisiana, on January 18, killing one person and injuring two others. It was part of a larger outbreak on the same date that spawned five other significant tornadoes near the Gulf Coast, with 20 total injuries. A smaller outbreak affected Central Florida ten days later, causing damaging F2 tornadoes in the Campbell–Orlando area, with 24 injuries. February featured much less activity, with 10 confirmed tornadoes compared to 33 in January, and no destructive or deadly tornadoes occurred. Outside the U.S., a catastrophic tornado, believed to be an F5, ravaged a small town in Argentina on January 10, causing more than 50 deaths.
