Brice, a meteorologist with the National Weather Service in El Paso, Texas, crunched the number of tornado touchdowns between 1950 and 2013. Then he plotted the Storm Prediction Center's data on two separate maps to show the latitudes and longitudes that have seen the most twisters during that time span.
Shortly after posting the two maps Monday on social media, they were rapidly distributed by meteorologists and weather geeks alike because they show a fascinating, fresh take on old statistics.
In the first map that filters tornado touchdowns by longitude, a line just east of 98 degrees west appears to have the most twisters in the 63-year span studied – a line of longitude that has seen more than 2,000 tornadoes during the time frame. This line cuts right through the middle of the Great Plains, and Brice's map shows the surrounding lines have also seen more than 1,500 tornadoes each.
