Why Tornadoes Take the Weekends Off in Summer

Here’s a really interesting bit of reasearch from the National Oceanic and Atmospheric Administration’s Storm Prediction Center. As National Geographic reported, it turns out that tornados occur more mid-week and incidents drop drastically over weekends.

The reason for this apparent anomaly is that during the week all the commuters get in their cars and drive to work, pumping pollutants into the atmosphere. Those pollutants serve as a perfect seed-bed for storm fronts, because moisture gathers around specks of pollutants, which leads to more cloud droplets, which leads to storms. Full story, here.
