Dirty air supercharges storms

but only in the Eastern part of the United States.

Scientists at NOAA’s Storm Prediction Center analyzed data from 1995 to 2009 and discovered that tornados and hailstorms occurred 20 percent above average in the middle of the week and 20 percent below average on the weekend.

They then investigated EPA air quality data and discovered that air pollution peaks midweek, mainly due to commuting traffic.

To find out how why air pollution can supercharge a storm and why it only happens in the Eastern part of the U.S. and not out West, check out this short article in National Geographic Daily News.

Another reason why we should look for ways to reduce our auto emissions.
