Tornado Alley: Home Of Extreme Winds
Apr 02, 2025•11 min•Ep. 1249
Summary
This episode explores the science behind Tornado Alley's high tornado frequency compared to similar geographic regions like South America. It discusses research highlighting the impact of land surface roughness on wind patterns and tornado formation. The conversation also touches on the complexities of linking climate change to tornado activity and the importance of considering terrain changes in understanding severe weather.Episode description
Each year, the United States has about 1,200 tornadoes. Many of them happen in tornado alley, a very broad swath of the U.S. that shifts seasonally. This area gets at least ten times more tornadoes than the rest of the world. Science writer Sushmita Pathak says that huge difference can be chalked up to one word: geography. But there's a slice of South America with similar geographical features that gets comparatively fewer tornadoes, so what gives? Sushmita wades into the research weeds with guest host Berly McCoy, one of Short Wave's producers.
