Greenfield: One of the Most Extreme Tornadoes Ever Measured

Radar-derived winds topped 300 mph, yet Greenfield received an EF4 damage rating. How can both findings be right? On May 21, 2024, a tornado crossed southwestern Iowa and struck Greenfield. This documentary follows its damage track, the Doppler on Wheels observations, and the survey evidence used to rate it. We examine what the wind estimates describe, why construction and gust duration matter, and how researchers compare radar data with turbine failures. The investigation ends with emerging research into the debris the tornado carried above the town. More natural-disaster documentaries from NatureUnbound:    / @natureunboundony
