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.
Read Sushmita's full article on tornadoes that she wrote for the publication Eos.
