Iowa Tornado Tears Through Town, Scientists Gather Rare Data on Destructive Twister

A devastating tornado tore through southern Iowa at a staggering speed of 45 mph, causing widespread destruction in its wake. The tornado, later classified as an EF4 by the National Weather Service, resulted in five fatalities and 35 injuries, making it one of the deadliest tornadoes of the year.

Scientific Pursuit Amidst Chaos

As more than a dozen tornadoes touched down in the state, a team of nine dedicated scientists, also known as storm chasers, fearlessly ventured closer to the twisters in an effort to gather crucial data. In the town of Greenfield, a community of about 2,000, the team strategically positioned their equipment and instruments, anticipating the tornado's path.

Close Encounter with Destruction

At nearly 3 p.m., the team seized a quick opportunity to position themselves within 10 miles west of Greenfield as a tornado formed. They courageously deployed scientific instruments directly in the twister's path, facing falling debris and the imminent danger of the approaching storm.

Calculated Risk and Unprecedented Data

Despite the inherent risks, the team successfully intercepted the tornado, collecting valuable data using advanced pod and radar devices. The data gathered is historic, as it marks only the third instance where wind speeds exceeding 300 mph within a tornado have been accurately calculated. The team's multi-angle readings during the tornado's assault on Greenfield provide a rare and detailed insight into the formidable winds and inner dynamics of such a powerful vortex, capable of devastating entire communities.
